BACKGROUND OF THE DISCLOSURE

1. Field of the Invention

[0006] The current disclosure generally relates to wireless data communication, and in particular to systems and methods for power conservation in wireless networks using frame aggregation.

2. Description of Related Art

[0007] Global internet traffic is growing at an unprecedented rate. There has been a corresponding reduction in cell sizes in order to eliminate coverage holes and deliver high data transfer rates to cell- edge devices.

[0008] IEEE 802.11 is part of the IEEE 802 set of local area network (LAN) technical standards and specifies the set of medium access control (MAC) layer and physical (PHY) layer protocols for implementing wireless LAN (WLAN) computer communication. IEEE 802.1 lad defines a PHY for 802.11 networks to operate in the 60 GHz millimeter wave spectrum. This frequency band has significantly different propagation characteristics than the 2.4 GHz and 5 GHz bands where Wi-Fi networks operate. The peak transmission rate of 802.11 ad is 7 Gbit/s. IEEE 802.11 ad is a protocol used for very high data rates and for relatively short range communication (about 1-10 meters). [0009] As just a specific example, wireless networks for environmental monitoring and surveying are experiencing tremendous growth in size and data quality as well. For instance, in oil and gas exploration, a total of 10,000 to 30,000 sensor nodes are deployed across an area of 100-300 square kilometers. Given that each sensor node typically generates data at a rate of 144 Kbps, the aggregate data rate at the sink node can be on the order of several Gigabits per second. Real-time acquisition at the sink node can enable the survey crew to increase productivity and drastically reduce carbon footprint.

[0010] The IEEE 802.11 protocol suite is an attractive option for wireless technologies that deliver high data rates and could deliver benefits when used for environmental monitoring and surveying given its unlicensed nature, low cost, and widespread availability of off-the-shelf hardware.

[0011] Frame aggregation is a technique utilized by the IEEE 802.11 standard to combine several individual data frames into a single aggregate frame for improved efficiency by eliminating recurring occurrences of control information (overhead). A reduction in the overhead can drastically enhance the overall throughput that can be achieved over a communication link, thereby making high-rate applications feasible.

[0012] However, there is a lack of technology that can provide considerable power savings in a wireless network employing the frame aggregation technique. A reduction of the power consumption is of paramount importance in both cellular networks and wireless LANs, particularly in high-rate applications that are known to be more power-hungry.

[0013] Conventional wireless networks employing frame aggregation include those disclosed in US Patent Nos. 10,206,168, 8,730,878 and 7,590,118, where a station that is receiving an aggregate frame can infer from some embedded schedule information whether the frame is intended for it or not. The station can accordingly suspend the reception of the remainder of the aggregate frame and enter low-power operation. Similar extensions are made to the multi-rate multi-user scenario in US Patent No. 7,983,203 and US Patent Publication No. 2006/0078001. In US Patent No. 7,733,835, the schedule information is sent as a separate control frame, prior to the aggregate frame. In US Patent Publication No. 2007/0191052, extensions are made to the automatic power save delivery (APSD) scheme in IEEE 802.1 In through frame aggregation. However, the size of the aggregate frame and duration of low-power operation (at the transmitting node) are not considered in these systems.

[0014] US Patent Publication No. 2018/0109463 and EP Patent No. 2451114 disclose that the buffer size at the receiving node is considered while preparing an aggregate frame for transmission. Additional factors such as congestion in the wireless network (US Patent No. 8,873,393) and interference (US Patent Nos. 9,319,926, 9,826,429 and 9,420,600) have been considered while determining the frame aggregation policy, albeit ignoring the aspect of power conservation. In CN Unexamined Patent Application No. 106455021A, an aggregate frame is created after a certain threshold is reached, the threshold either being a certain number of data frames or a certain time threshold. After the transmission of the aggregate frame, the system switches to low-power operation. However, CN 106455021 A is silent on a duration for such a low-power operation, and what parameters such a duration would be based on.

[0015] Thus, technological innovation is needed to provide power savings in a wireless network employing the frame aggregation technique and/or a low-power mode. Thus, one focus of the present invention concerns the use of frame aggregation as a means to minimize the power consumption in large-scale wireless mesh networks. Another focus of the present invention concerns the use of a low-power sleep mode as a means to minimize the power consumption in large-scale wireless mesh networks. Power saving performance can be from an approximately 78% drop (and more) in total power consumption under such improvement(s) as compared to the classical scenario (where there is no use of frame aggregation and/or a sleep duration imposed on sub-links).

[0172] A WLAN is a popular type of a wireless network technology. A WLAN may be used to interconnect various devices together, either in an indoor or outdoor setting. The IEEE 802.11 protocol is a highly popular technology employed in such scenarios. In indoor scenarios, the primary objective may be to deliver reliable data for the purposes of connectivity and entertainment. In outdoor scenarios, point-to-point links can be established in the form of a mesh network for cellular backhaul. Backhaul links may also be deployed across long distances in large-scale environmental surveying/monitoring applications such as oil and gas exploration.

[0173] With the proliferation of wireless devices and an ever-growing demand for high-quality data, there is a strong need for wireless technology that can support very high data rates on the order of several Gigabytes per second. Frame aggregation (FA) and frame bursting are two techniques that have been incorporated into the IEEE 802.11 standard that can help improve the overall throughput. As per the working of the IEEE 802.11 standard, each data frame is associated with some inherent overhead in the form of metadata. The metadata may be control signals at the PHY, that deals with the process of automatic gain control, channel estimation, error detection and correction, time synchronization, and frequency carrier offset correction. Additionally, the metadata may indicate MAC layer information such as identification information, the type of data being contained in the payload, the modulation and coding scheme (MCS) being employed, and various other parameters.

[0174] With the use of frame bursting and FA, a plurality of such data frames is combined into a single “block” frame such that the overhead is significantly reduced. For instance, the payload duration for a packet of 1500 bytes is around 3 microseconds, considering a 4 Gbps link using the IEEE 802.1 lad standard. However, the MAC layer overhead can amount to nearly 60 microseconds, which drastically brings down the effective data rate to just around 0.2 Gbps. Hence, the use of larger data blocks is imperative to achieving a high throughput by diminishing the effect of the overhead.

[0175] Those of skill in the art appreciate the MAC layer improvements introduced in the IEEE 802.1 In amendment by the IEEE 802.11 working group. Frame bursting and FA were proposed as a part of this amendment, and further enhancements were made in later amendments, such as more efficient integration with the block acknowledgment protocol.

[0176] Referring to FIG. 2, the MAC layer organizes data in the form of individual data frames 200, 201, 202 known as MAC service data units (MSDUs). An MSDU comprises a payload portion (containing data from the upper layers of the protocol stack) and a header portion that contains metadata. Typically, after each MSDU is transmitted, an acknowledgement (ACK) frame is expected by the transmitter as per the IEEE 802.11 standard specifications.

[0177] A sequence of MSDU-ACK exchanges is highly inefficient, particularly in the case of high- rate protocols such as 802.1 lad. In frame bursting, several MSDUs are transferred back-to-back, with adjacent MSDUs being separated in time by the reduced interframe spacing (RIFS). At the end of the burst, a block ACK (BA) is sent back to the transmitter containing information about which of the MSDUs were not received successfully and require retransmission.

[0178] The efficiency of data transfer can be further improved through FA, wherein the RIFS period is eliminated and the header fields combined to reduce the impact of the overhead. The resultant frame may be referred to as an aggregate frame. As shown in FIG. 2, several MSDUs may be aggregated to form an Aggregate MSDU (A-MSDU) frame 203. A MAC protocol data unit (MPDU) is formed by attaching additional header and frame check sequence (FCS) fields to an A- MSDU. Several MPDUs may in turn be aggregated to form an Aggregate MAC Protocol Data Unit (A-MPDU) frame 204. The A-MPDU frame is then passed in the egress direction to the PHY layer to form the final payload frame for transmission.

[0179] A combination of both A-MSDU and A-MPDU aggregation can be employed as per the IEEE 802.11 standard specifications. The overall effect is a significant reduction of the overhead, and the ability to boost the data rate by forming very large data blocks.

[0180] An example wireless network shown in FIG. 3 is a frequent occurrence in modern-day networks. Stations (STAs) 300, 301, 302, 303, 304 exchange data with access points (APs) 305, 306 through bidirectional communication links 308. The APs in turn exchange data with a central data unit (CDU) 307. The CDU may also serve as a gateway node to a larger backbone network.

[0181] The bidirectional communication links may be operated as per the IEEE 802.11 standard and may frequently invoke the frame bursting or FA mechanisms. In an exemplary embodiment, the STAs are devices such as smart phones, laptops, smart televisions etc. The APs may be controlled by a CDU that governs the operation of the WLAN(s). In another exemplary embodiment, the APs serve as radio units for small cell coverage and can establish backhaul links to the core network in cellular systems. In another exemplary embodiment, the STAs serve as sensors in an environmental surveying/monitoring system that can find application in oil and gas exploration, weather monitoring, agricultural monitoring, earthquake detection, and other meteorological studies. The APs would serve as relay nodes that transfer data towards the CDU, which in turn governs the operation of the entire monitoring system. In another exemplary embodiment, all the devices in the shown network can exchange data with one another in a mesh topology. Hence, the example wireless network shown in FIG. 3 can be applied to a variety of scenarios.

[0182] In addition to sustaining high data rates, there is an equally important need for power conservation to extend the operating time of wireless devices. In particular, achieving the optimal trade-off between latency and power conservation with the use of frame bursting or FA remains an open problem.

[0183] The present invention provides power-conserving systems and methods in, for example, a wireless network as shown in FIG. 3. Provided that the achievable rate of communication is greater than the arrival rate of data, a low-power sleep duration can be imposed at each of the devices in the network.

[0184] An shown in FIG. 4, primary aspects of the present invention include a method 400, where a wireless device can determine the arrival rate of data at step 401 along with the amount of data to be scheduled for transmission or reception at step 402. This amount of data can be divided across a number of data frames, which in turn are scheduled for transmission.

[0185] At step 403, the value for the sleep duration t can be determined as a function of various parameters in addition to the arrival rate of data and the amount of data that is scheduled for transmission or reception. The wireless device at step 404 may then operate in low-power sleep mode for the prescribed duration t, followed by a frame bursting transmission or a FA transmission step 405. In the case of a receiving device, the sleep duration may be followed by a frame bursting reception or a FA reception. A transmitting device may also operate in unison with another receiving device under a common period of low-power sleep mode and data transfer.

[0186] Data may “arrive” at a device as a result of data generation (such as a sensor), and/or through a receiver that decodes incoming transmissions and buffers the data, and/or through a combination of both the aforementioned factors. The arrival rate of data may be computed or estimated through a variety of means. Those of skill in the art can appreciate the use of mathematical models based on queuing theory for determining the arrival rate of data. The model may be deterministic or statistical in nature, based on the type of traffic encountered. In applications such as oil and gas exploration, the traffic pattern is deterministic and suitable models may be applied. In applications such as cellular backhaul, the traffic pattern may be modeled using statistical distributions such as the Poisson model. Alternatively, a custom empirical model may be applied by the wireless device to determine the arrival rate of data. The value of the computed arrival rate may also be modified as per any data compression algorithms that are applied by the device.

[0187] The amount of data to be scheduled for transmission (or reception) may be computed as a function of various parameters in the wireless device and the wireless network. Such parameters include, but are not limited, to the latency, power consumption, uniformity of power consumption, quality-of-service (or traffic category of the data), buffer size, communication rate (or MCS index), and transmission power at each of the wireless devices in the wireless network. The amount of data may then be divided across a number of data frames, which in turn are scheduled for transmission (or reception) as per the predefined PHY/MAC layer protocol. The data frames may in turn be transmitted using a frame bursting or a FA mechanism.

[0188] Above described aspects of the present invention pertain to individual wireless devices that determine the operating parameters independently of another. Each of these devices operates in a distributed manner that is agnostic to the latency and power consumption requirements that may be desired by the wireless network (or a backbone network) as a whole. In some cases, a central entity may wish to dictate the operation of a larger part of the network under certain constraints.

[0189] Further aspects of the disclosure are described with reference to FIG. 5 where a mesh network for backhaul application is shown with the arrival rates of data at each of the devices. APs 500, 501, 502 form a mesh network with the objective of relaying or “backhauling” data towards the CDU 403. AP 500 perceives an arrival rate of Ri, AP 501 perceives an arrival rate of (R₂ + Ri). AP 502 perceives an arrival rate of ( R4 + Rs), and AP 503 perceives an arrival rate of Re. Those of skill in the art appreciate that in order to maintain a stable queue without introducing exponential delays, the conditions ( R2 > Ri), ( R4 > R2+R3), and (Re > R4+R5) would have to be satisfied. Furthermore, there may be latency requirements at the CDU 503 in addition to a power consumption requirement at all the APs. In such a scenario, the number of data frames that are scheduled for transmission and reception at the various APs would have to be jointly solved (on the basis of all the arrival rate values) to obtain the optimal power conservation performance under a latency constraint. APs 500 and 501 may operate in low-power sleep mode in unison, and wake-up at the same time instance such that the transmitter in AP 500 transmits an amount of data towards the receiver in AP 501. A similar approach may be taken by APs 501 and 502, and AP 502 and CDU 503.

[0190] Those of skill in the art can appreciate the use of convex approximation methods to capture the effect of the amount of data (that is scheduled for transmission/reception at each of the APs) on the power consumption and the latency. This in turn can yield a convex optimization problem which can be rapidly solved for the globally power-optimal solution using standard techniques. The aforementioned optimization problem can be extended to solve for the optimal MCS index and transmission power for all the APs, under the impact of CCI as well.

[0191] Another aspect of the invention pertains to coexistence between various STAs in a wireless network while applying the aforementioned techniques for power conservation. As shown in FIG. 6, two separate communication links between the STAs may operate concurrently by multiplexing the transmissions either in time or frequency. For instance, the communication links AP 600 - AP 601 and AP 602 - AP 603 can operate simultaneously on unique frequency channels Fi and F2 respectively. Alternatively, transmissions over the communication link AP 604 - AP 605 can be performed during the low-power sleep mode duration of the communication link AP 606 - AP 607, in order to prevent interference on a common channel F3. In another embodiment, an external AP 510 can transmit time-sensitive data, over a common channel F4, during the low-power sleep mode duration imposed at APs 608 and 609. In such a scenario, AP 609 would have to alter its low-power sleep mode duration (that was scheduled in conjunction with AP 608) and wake-up to receive the transmissions from AP 610. In applications such as environmental monitoring and oil and gas exploration, the external AP 610 may be a mobile device such as an unmanned aerial vehicle (UAV) or an autonomous underwater vehicle (AUV) that periodically joins the network to transfer time- sensitive information.

[0192] Energy-Efficient mm -Wave Backhauling via FA in Wide Area Geophone Networks

[0193] As previously discussed, the present systems and methods afford innovation advances in specific situations, for example, in wide area geophone networks. Recent advances in exploration geophysics can generate subsurface images of the Earth with great depth and quality, albeit requiring a large amount of seismic data to be transferred in real-time. While cables are able to meet these requirements, they account for a majority of the equipment weight, maintenance, and labor costs.

[0194] In an exemplary embodiment of the present invention, an innovative wireless network architecture compliant with the IEEE 802.1 lad standard is disclosed for establishing scalable, energy-efficient, and gigabit-rate backhaul across very large areas. Statistical path-loss and line-of- sight (LoS) models are derived using real-world topographic data in well-known seismic regions. Additionally, a cross-layer analytical model is derived for 802.11 systems that can characterize the overall latency and power consumption under the impact of CCI.

[0195] On the basis of these models, an FA-PSB scheme is disclosed for near-optimal power conservation under a latency constraint, through a duty-cycled approach. A performance evaluation with respect to the survey size and data generation rate reveals that the innovative architecture and the FA-PSB scheme can support real-time acquisition in large-scale high-density scenarios, while operating with minimal power consumption, thereby enhancing the lifetime of wireless seismic surveys. The FA-PSB scheme can be applied to cellular backhaul and sensor networks as well.

[0196] Wide area data acquisition systems for surveying applications continue to grow in area, node density, and data traffic. In particular, one such challenging application is the operation of seismic surveys for imaging the subsurface layers of the Earth to determine the location and size of oil, gas, and other mineral deposits. Seismic waves are generated by an energy source that are reflected by the subsurface layers, and in turn recorded by devices called geophones that are deployed across the survey area. The data is then accumulated at a data collection center (DCC) and processed to generate a visual image of the Earth’s subsurface.

[0197] The subject of 2-D and 3-D seismic survey design has been studied. As noted above, a typical survey can deploy 10,000 to 30,000 geophones over an area of 100-300 square kilometers. Given the sheer size of a seismic survey, the use of cable to connect all the geophones accounts for a majority of the equipment weight and cost. Although cable can offer high data rates in a reliable manner, a significant amount of time is spent in troubleshooting problems pertaining to the cables and connectors. Deploying cable in undulated terrain is a challenging task and can pose safety hazards to the crew. Cables can also directly impact the ecosystem of the region. For instance, it has been reported that some length of the cables is chewed upon by animals overnight leading to unmonitored ecological effects in addition to maintenance setbacks in the surveying process.

[0198] While wireless systems offer an excellent alternative to cable, they come with the challenging task of achieving high data rates and relaying time-sensitive information over several nodes deployed across a widespread area. Real-time acquisition at the DCC is of vital importance as it enables field engineers to adaptively modify the acquisition parameters and minimize logistical costs. Given a seismic wavefield sampling time of 0.5 ms, a three-component (3-C) geophone with a 24-bit analog-to-digital converter would generate data at a rate of 144 Kbps. For a mid-sized survey comprising 3-C 14,400 geophones, the data rate requirement at the DCC can reach up to 1 Gbps. Larger surveys with higher sampling rates at the geophones would mandate a requirement of nearly 5 Gbps at the DCC. In this regard, geophone networks vary vastly from typical sensor networks where the peak data rate is on the order of a few Kbps. Additionally, power saving schemes must be incorporated since seismic acquisition can be conducted for durations lasting up to thirty days.

[0199] The present invention embodied as a wireless geophone network architecture provides high- rate energy-efficient data transfer between the gateway nodes and the DCC, which is a crucial aspect that has not been studied. The IEEE 802.1 lad standard is a suitable choice that can sustain data rates of up to 6 Gbps in the 60 GHz unlicensed bands and achieve real-time acquisition at the DCC even for large-scale surveys that impose an acquisition rate requirement of up to 5 Gbps. [0200] A complete latency and power consumption analysis is conducted for gateway nodes that are spread across the entire survey area. Furthermore, an analytical model is extended to include the impact of the transmit power and MCS index at the PFIY layer, FA at the MAC layer, and the use of transmission control protocol (TCP) at the transport layer. Multiple source nodes are considered, as opposed to a single source. The present invention uses an FA-PSB scheme for near-optimal power conservation across a large-scale mesh network of gateway nodes, while ensuring real-time data delivery at the sink node. A duty-cycled approach is taken wherein the aforementioned analytical models are applied in determining near-optimal values for the sleep duration and data transmission parameters across the entire network.

[0201] Although primarily focused on the use of IEEE 802.1 lad in seismic acquisition, the present invention extends to various other applications, such as 5G small-cell mm-wave backhaul, wireless backhaul in heterogeneous networks (HetNets), and sensor networks based on IEEE 802.11 systems for agricultural, environmental, and industrial monitoring purposes.

[0202] The present invention incorporates, among other features:

[0203] - the design of a wireless network architecture for real-time, scalable, standards-compliant, and energy-efficient backhauling across large areas. The architecture is augmented with the inventive FA-PSB scheme that relies on a duty-cycled approach for near-optimal power conservation;

[0204] - the derivation of a cross-layer analytical model, based on semi-Markov processes and queuing theory, that characterizes the data transfer time and power consumption as a function of the transmit power, MCS index, FA parameters in 802.11, along with the use of TCP; and

[0205] - the derivation of an optimization framework that yields the parameters for operation under the FA-PSB scheme. A convex mixed-integer non-linear program (MINLP) is formulated and solved to achieve minimum power consumption across the network under the impact of CCI and a latency constraint.

[0206] An overview of the seismic survey process is shown in FIG. 7. The geophones can be considered the STAs of FIG. 3. The wireless gateway nodes (WGNs) can be considered the APs of FIG. 3, and the DCC analogous to the CDU.

[0207] The geophones are positioned 5-30 meters apart, along a straight line to form a Receiver Line (RL). Vibroseis trucks move along a Source Line (SL) and generate seismic waves, called a “sweep,” for a duration of 8-12 seconds, known as the “sweep length.” Following the sweep length, data is recorded by all the geophones for a duration of 6-8 seconds, known as the “listen interval.” During a “move-up interval” of 8-10 seconds, the vibroseis trucks shift to the next point where a sweep will be conducted. The three operations are repeated periodically across the survey area. A “flip-flop” operation is where two vibroseis trucks that are sufficiently separated in distance can conduct overlapping sweeps to improve the overall productivity. Typically, there is no rigid latency requirement at the DCC. However, a good benchmark would be to acquire all the data from the previous sweep prior to the start of the listen interval of the current sweep, thereby enabling the field engineers to modify the recording parameters at the geophones. Hence, the latency threshold at the DCC can be set to the duration of the sweep length.

[0208] An orthogonal geometry is a commonly employed topology in seismic acquisition, wherein the RLs and SLs are perpendicular to one another. FIG. 7 provides an illustration of an exemplary embodiment of the present invention as a network architecture that specifies an inter-geophone distance of 25 meters along the RL, and an inter- RL distance of 200 meters. The bottommost layer of the architecture, Li, includes the links between WGNs and the geophones. As shown in FIG. 7, the WGNs are laid out in a hexagonal tessellating pattern to minimize CCI, where R is the WGN cell radius defined as the distance from the center to the comer of the hexagon. A variety of communication schemes can be used for operation at the Li layer.

[0209] The upper L2 and L3 layers are organized as a mesh network of WGNs with the DCC being the final sink node. Although both upper layers are part of the same mesh network, the notations L2 and L3 serve to demarcate the overall mesh into smaller subnets having either a vertical (L2) or a horizontal ( L3 ) orientation. Note that the peak data transfer rates at the L2 and L3 layers are significantly higher (0.15-2.5 Gbps) as compared to the Li layer (1.5-150 Mbps). Hence, the IEEE 802.11 ad standard can be employed at the L2 and L3 layers in order to provide a real-time acquisition capability.

[0210] To improve the robustness of the architecture, additional relay nodes (RNs) can be deployed uniformly between adjacent WGNs, so as to counter large path losses in the 60 GHz bands or non- line-of-sight (NLoS) conditions.

[0211] At the L2 layer, obstructions to diagonal communication links between the WGNs are inevitably created by the vibroseis trucks, thus inhibiting direct data transfer along the shortest path from the WGNs to the DCC. Tall antennas can be deployed to counter this problem, albeit requiring several such setups across the entire survey area that are robust enough to tackle high wind speeds. Hence, a more tractable solution is to employ a directional radiation pattern at the L2 layer, so as to relay data in a direction parallel to the SLs as shown in FIG. 7.

[0212] The topmost L3 layer, comprising the DCC, forms the bottleneck of the entire network. Since the entire network topology is fixed for long durations of time, single-hop static routing can be applied. Considering a maximum antenna height of 1 meter at the WGNs and RNs, CCI between neighboring cells is effectively subdued by a larger path loss and a lower LoS probability at longer distances, implying that concurrent transmissions can occur between pairwise nodes.

[0213] As illustrated in FIG. 7, a “path” is defined as a set of WGNs and RNs, beginning from any outer WGN at the L2 layer and leading up to the DCC. Each path comprises various “links” between adjacent WGNs. Each link is further divided into “sub-links” between adjacent RNs.

[0214] In addition to achieving real-time acquisition, power conservation is of vital importance not only in seismic survey applications, but many others. In the case of IEEE 802.1 lad, the payload transmission time is significantly lesser as compared to the overhead time associated with the PHY header, inter- frame spaces, and MAC-layer backoff. For each data packet transmission, the overhead inadvertently leads to an increase in the power consumption.

[0215] In order to counter the impact of this overhead, FA techniques can be employed. As disclosed, multiple data packets can be aggregated into a single frame for transmission, thereby eliminating the recurrence of the overhead. The degree up to which FA is applied, i.e., the number of individual data packets that are aggregated, can be termed as the aggregation length. At the MAC layer, data is encapsulated into separate MSDUs, which can be aggregated to form the A-MSDU frame.

[0216] As shown in FIG. 2, the incoming MSDUs may be sequentially aggregated until a maximum size threshold is attained. An A-MSDU is then appended with a header and an FCS to form a MPDU. As per the chosen aggregation length, the requisite number of MPDUs are in turn aggregated into the A-MPDU frame. The A-MPDU frame is then passed in the egress direction to the PHY layer to form the final payload frame for transmission. A combination of both A-MSDU and A-MPDU frames has been shown to perform best.

[0217] The performance of FA can be further improved with block acknowledgements (BAs), where the acknowledgements for each of the MPDUs can be combined into a single frame. A block acknowledgement request (BAR) is sent by the transmitter after the A-MPDU frame, following which a BA is sent back by the receiver, which contains a bitmap corresponding to the MPDUs that have failed reception. Since each MPDU is associated with its own unique FCS for error detection, only those MPDUs that were not delivered successfully are required to be retransmitted. The overall effect is a substantial reduction in the amount of overhead that would otherwise be amplified in the case of individual data-acknowledgement exchanges.

[0218] The present invention provides effective power conservation. In addition to reducing the overhead with respect to time, FA can be exploited to achieve relatively large power savings. For instance, a geophone can abstain from transmitting data for a duration of sleep in order to buffer a requisite number of packets while conserving power, after which real-time acquisition can still be perceived through a burst transmission of the buffered data using FA. The FA-PSB scheme relies on a cross-layer analytical model and optimization framework to determine the sleep duration and other parameters for data transmission, such as the transmit power, MCS index, and the aggregation length. Overall, highly effective power conservation is achieved across the backhaul network while adhering to any latency constraints at the DCC.

[0219] IEEE 802.11 devices typically require a minimum duration of 250 ps to “wake-up” from sleep mode operation. Additionally, time synchronization should be maintained between adjacent nodes, where a timing synchronization function can provide an accuracy of 4 ps, which is negligible in comparison to the value of the minimum duration. Thus, the minimum duration can implicitly serve as a guard time for countering the possible effects of incorrect synchronization.

[0220] The present invention further provides robustness against CCI. CCI can lead to a decrease in the SINR at the receiver, which in turn can lead to a higher packet error rate. In general, the impact of CCI in the present inventive network is not severe, owing to a lower LoS probability and a higher path loss (due to atmospheric absorption) at larger distances. However, the FA-PSB scheme can operate in the presence of CCI as well.

[0221] Given that the arrival rate of data at a node is deterministic, the resultant durations for operating in sleep mode and data transfer can be computed, following which the duty cycle for the corresponding sub-link can be found. As shown in FIG. 8, interference would occur between two co-channel cells when the data transmission periods (represented by the “on” state of the duty cycles) overlap. Since the occurrence of such overlapping transmissions can be found in a deterministic manner, the robustness of the sub-links can be ensured by altering the operating parameters such as the transmit power or the MCS index. These parameters can be obtained a-priori through a heuristic algorithm based on a combination of power and rate control that maintains a low outage probability. Hence, the deterministic nature of traffic in geophone networks can be exploited to compute the time instances when CCI would be present, following which the operating parameters are preemptively modified to ensure robustness against CCI.

[0222] The present invention further provides TCP over mesh networks with large hop-count. TCP is not well-suited for mesh networks with a large number of hops since an acknowledgement from the receiver that is delayed extensively would be interpreted as packet loss by the transmitter. This problem can be overcome by maintaining single-hop TCP links between adjacent RNs (and WGNs), rather than having a dedicated TCP connection between each of the WGNs and the DCC.

[0223] The present invention further provides standards-compliance: The present FA-PSB scheme is designed to be compliant with the TCP/IP protocol suite at the transport and network layers, along with the IEEE 802.11 protocol at the MAC and PHY layers. The functionality of the present FA- PSB scheme can be implemented by making appropriate changes to the device drivers or firmware, without requiring modifications to the specifications dictated by the relevant standards.

[0224] Modeling two surveys generally related to the architecture of FIG. 7 using the present invention illustrate the beneficial results. Considering a 4-cell reuse pattern and a sweep length of 8 seconds, the performance with respect to the latency and power consumption (at the L2 and L2 layers) is evaluated for a SA and a TX survey terrain.

[0225] The SA survey represents a mid-sized survey comprising 14,400 geophones over an area of 72 square kilometers, while the TX survey represents a large survey comprising 57,600 geophones over an area of 288 square kilometers. The resultant values are averaged over 1000 Monte Carlo trials, wherein the geophone network is deployed over a random section (as per a uniform distribution) of the seismic survey region in each trial.

[0226] Simulations are conducted using ns-3 for the IEEE 802.1 lad standard. The simulation parameters are shown in Table I:

Table I - Simulation Parameters

[0227] Standards-compliant values of a contention window size ( CW) of CW_min = 16 and CW_max 1024 are considered, such that M- 6 (where the TCP payload segment or TCP acknowledgement would have to be resent after M retransmissions at the MAC layer). The latency and the total power consumption for the SA and TX surveys operating under the FA-PSB scheme is shown in FIGS. 9A, 9B, 10A, and 10B as a function of the WGN cell radius R, for a geophone data generation rate of 144 Kbps. While the latency ranges between 0.5 - 2.2 seconds, which is well within the value of the sweep length, the power saving performance is abundantly clear, with a 78-87% drop in the total power consumption under the FA-PSB scheme as compared to the classical scenario (where there is no sleep duration imposed on the sub-links).

[0228] The number of WGNs decreases with increasing values of R, which explains the descending trend in the latency and power consumption. However, certain non-linearities are introduced in the trend since the total number of RNs does not monotonically decrease with R. For instance, an abrupt increase in the latency and the power consumption is seen in both surveys around R - 570 meters. This is due to the fact that the outage probability threshold can only be met by the introduction of additional RNs. Hence, although it may seem counter-intuitive that the power consumption would increase despite a drop in the number of WGNs, it is important to consider the number of RNs that are required to sustain reliable and real-time acquisition for larger values of R.

[0229] FIGS. 10A, 10B illustrate that the overall latency and power consumption in the TX survey is larger as compared to the SA survey, which arises due to two factors. First, the TX survey area mandates a larger number of WGNs and RNs as it is four times larger in size. Second, the TX survey terrain is characterized by a lower LoS probability, which in turn would require a larger number of RNs to be deployed.

[0230] Furthermore, the effectiveness of the present analytical technique can be seen in FIGS. 9A, 9B, 10A, and 10B. The impact of the data generation rate at each of the geophones (multiples of 48 Kbps) is studied for R - 400 meters. As seen in FIGS. 11A, 11B, a maximum rate of 768 Kbps can be sustained by the present 802.1 lad-based architecture for the SA survey. The latency observes a decreasing trend in FIGS. 11 A, 12 A, since the sleep duration is reduced in order to maintain queue stability at higher values of the packet arrival rate. A corresponding increase is seen in the power consumption, where the WGNs and RNs are required to operate in transmit and receive modes for a greater fraction of time.

[0231] In the case of the TX survey, a maximum data generation rate of 192 Kbps can be applied at the geophones. Note that the analysis deals with the transfer of raw data from the geophones to the DCC. However, data compression techniques can be utilized to reduce the effective packet arrival rate, which in turn can substantially enhance the power conservation performance of the FA- PSB scheme.

[0232] FIGS. 13A, 13B, 14A and 14B illustrates a performance comparison between the use of the IEEE 802. l lad and IEEE 802.1 lac standards under a latency-constrained scenario for the SA survey. When low-rate alternative applications such as seismic quality control or earthquake detection are considered, where the data generation rate can be as low as 1 Kbps, a latency of several minutes may be introduced by the FA-PSB scheme. Thus, a latency constraint would be deemed necessary in such scenarios, at the cost of a marginal increase in the power consumption. The tradeoff between the latency and the power consumption is shown in FIGS. 13A, 13B, 14A and 14B for the SA survey and for R - 400 meters. Considering a data generation rate of 48 Kbps in FIGS. 13A and 13B, it can be seen that the 802.1 lad standard is able to achieve a much lower power consumption as compared to 802.1 lac, by exploiting its gigabit-rate capability to increase the sleep duration while maintaining queue stability. [0233] In the case of a data generation rate of 1 Kbps in FIGS. 14A and 14B, the power conservation benefit that is provided by the 802.1 lad standard is only marginal as compared to the 802.1 lac standard. Hence, the 802.1 lac standard may be deemed a feasible choice in low-rate applications but fails to provide satisfactory results in the case of data-intensive seismic acquisition.

[0234] For instance, the maximum data generation rates that can be sustained by the 802.1 lac standard are only 1 and 48 Kbps in the case of the SA survey, and just 1 Kbps in the case of the TX survey. Since the maximum PHY-layer rate is only around 440 Mbps for the standard 80 MHz channels, higher data generation rates at the geophones would lead to queue instability and an exponential latency at the DCC.

[0235] Seismic acquisition at the DCC, the final sink node for the entire geophone network, mandates data transfer rates on the order of several gigabits per second in order to have real-time data delivery, in addition to the acquisition process being energy-efficient. A wireless geophone network architecture based on the IEEE 802.11 ad standard has been evaluated as disclosed under the impact of CCI for a combination of the seismic survey size, number of geophones, data generation rate, and survey terrain in Saudi Arabia and Texas, USA.

[0236] On the basis of statistical models for the path loss and LoS probability, and a cross-layer analytical model for the latency and power consumption, an optimization framework is developed to achieve near-optimal power conservation performance through the FA-PSB scheme. A performance evaluation at a data generation rate of 144 Kbps reveals that the power consumption can be reduced by up to 87% with a maximum latency of around 2 seconds at the DCC, as compared to classical operation prescribed by the 802.11 ad standard. Although approaches based on the IEEE 802.1 lac standard are feasible for low -rate applications such as earthquake detection and seismic quality control, the present invention’s use of the IEEE 802.1 lad standard is far more suitable for data-intensive real-time environments, like seismic acquisition.

[0237] The power conservation performance of the FA-PSB scheme can be further enhanced by utilizing a higher value for an upper bound on the aggregation length, which could be tweaked in vendor-specific implementations to support larger A-MPDU frame sizes. Additionally, data compression techniques can be incorporated to reduce the overall packet arrival rate at the WGNs, which in turn would enable the FA-PSB scheme to conserve more power. A reduction in the power consumption translates to a reduced cost in terms of the equipment weight, transportation, and manpower. The present architecture also offers a low-cost alternative to current seismic data acquisition systems by eliminating cable and reducing the overall power consumption. Furthermore, the FA-PSB scheme can find application in cellular backhaul and large-scale sensor networks for effective power conservation.
