Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.
In the description of the present invention, unless explicitly defined otherwise, terms such as arrangement, installation, connection, etc. should be construed broadly and the specific meaning of the terms in the present invention can be reasonably determined by a person skilled in the art in combination with the specific contents of the technical scheme.
Referring to fig. 1, a data identification method according to an embodiment of the first aspect of the present invention includes:
step S100, data to be identified is obtained.
The data to be identified may be air interface data received by the network node from the receiving channel. For example, in a wireless ad hoc network CSMA/TDMA unicast or multicast long frame reception scenario, in a network of N (neighbor) nodes, each node may receive unicast and multicast data from a reception channel of the node, so the node may receive the data to be identified. Alternatively, the data to be identified may be set according to the requirement, and the frame structure of the data to be identified may include a frame start portion and a frame body portion, wherein the length of the frame body portion is variable.
Step S110, analyzing the data to be identified, and extracting to obtain target identification information and receiving duration.
Wherein the target identification information may be information for identifying a network node receiving the data to be identified, for example, the target identification information may include a receiving address (unicast or multicast address) or a receiving node identification; the reception duration may be a duration required for receiving/transmitting the data to be identified, and the reception duration may include a reception duration and a transmission duration. Optionally, the data to be identified may include target identification information and a receiving duration, for example, the target identification information and the receiving duration may be set in a frame beginning portion (or a frame header) of the data to be identified, and then the node may preferentially analyze the frame beginning portion of the data to be identified, so as to obtain the target identification information and the receiving duration.
And step S120, carrying out identification processing based on the target identification information, and if the target identification information does not meet the identification requirement, carrying out node power consumption reduction processing according to the receiving duration.
The identifying process may be identifying and judging whether the data to be identified is the data to be sent to the node or the data to be forwarded by the node; the identification requirement may be a specific condition for judging whether the target identification information meets the requirement; the power consumption reduction processing of the node can be to control the signal of the node so as to achieve the operation of reducing the power consumption. Optionally, the identifying and judging can be performed according to the target identification information, so as to determine whether the data to be identified is the data to be sent to the node or the data to be forwarded by the node: if the data to be identified is not the data sent to the node or the data which does not need the node to forward is identified, the target identification information can be determined to be not in accordance with the identification requirement. Under the condition that the target identification information does not meet the identification requirement, the node can terminate receiving the data to be identified in advance without forwarding, and further can perform power consumption reduction processing on the node, such as frequency reduction, voltage reduction, clock closing, power supply closing and the like, so that the power consumption of the node can be reduced.
According to the data identification method, the data to be identified is obtained, then the data to be identified is analyzed to obtain the target identification information and the receiving duration, finally the identification processing is carried out based on the target identification information, if the target identification information does not meet the identification requirement, the node power consumption reduction processing is carried out according to the receiving duration, the identification data can be analyzed rapidly, and the power consumption of node receiving and sending is reduced.
In some embodiments of the present invention, if the target identification information does not meet the identification requirement, the method includes:
local identification information is acquired. The local identification information may be characteristic information of the node, and the local identification information may include an address of the node or an identity of the node. Optionally, different network nodes correspond to different local identification information, so that the local identification information corresponding to the node can be obtained, and the target identification information can be identified according to the local identification information.
And comparing the target identification information with the local identification information, wherein if the target identification information is different from the local identification information, the target identification information does not meet the identification requirement. Optionally, assuming that the target identification information may include a target receiving address or a target receiving node identification, and assuming that the local identification information may include an address of the node or the node identification, the target identification information and the local identification information may be compared, for example, the receiving address may be compared with the address of the node, and the receiving node identification may be compared with the node identification, to determine whether the received data to be identified is data addressed to the node, thereby implementing the identification processing of the target identification information. Specifically, for example, in TDMA networks, if the received address or received node identification field is different from the address or identification of the node and is not a broadcast address, then early termination of reception is triggered. In another example, in the CSMA network, the receiving node receives and analyzes the duplex and RA fields in the RTS/CTS frame, and if it is identified that RA is not the address of the node and RA is not the broadcast address (i.e. the target label information is compared with the local label information), the receiving node triggers early termination of the receiving. If the target identification information is different from the local identification information, it can be determined that the received data to be identified is not the data sent to the node, or the received data to be identified does not need to be forwarded by the node, and further it can be determined that the target identification information of the data to be identified does not meet the identification requirement, so that the receiving or forwarding of the data to be identified is stopped. By comparing the obtained local identification information with the target identification information, if the target identification information is different from the target identification information, the received data to be identified can be accurately judged not to be the data sent to the node, the target identification information can be determined not to meet the identification requirement, and the data to be identified can be quickly identified.
In some embodiments of the present invention, the identifying process based on the target identification information includes:
if the target identification information is the same as the local identification information, the target identification information meets the identification requirement. Alternatively, the target identification information may include a target receiving address or a target receiving node identification, and the local identification information may include an address of the local node or the local node identification. The receiving address can be compared with the address of the node, the receiving node identification is compared with the node identification, whether the received data to be identified is the data sent to the node is judged, if the target identification information is the same as the local identification information, the received data to be identified is the data sent to the node, or the received data to be identified needs to be forwarded by the node, and further the target identification information of the data to be identified can be determined to meet the identification requirement.
And receiving the data to be identified. Optionally, if the target identification information of the data to be identified meets the identification requirement, the node can normally receive the data to be identified, namely, continue to receive the data to be identified, or normally forward the data to be identified, so as to implement the receiving process of the data to be identified. Under the condition that the target identification information is the same as the local identification information, the received data to be identified can be determined to be the data sent to the node, or the received data to be identified needs to be forwarded by the node, and the target identification information meets the identification requirement, so that the data to be identified can be received and processed, and the data to be identified can be quickly identified.
In some embodiments of the present invention, performing node power down processing according to a reception duration includes:
and acquiring a preset threshold value. The preset threshold may be a critical value corresponding to the duration of reception. Optionally, the preset threshold may be set according to requirements, and the preset threshold may also be multiple. The threshold value of the receiving duration time can be set to judge whether the receiving duration time meets the requirement of a preset threshold value.
And if the duration of the receiving is longer than a preset threshold, controlling to carry out the power consumption reduction processing of the node. The power consumption reduction process may be an operation of reducing power consumption of the receiving node. If the duration of the reception is longer than the preset threshold, it can be determined that the duration of the power reduction is long enough, or the duration of the reception is longer than the power reduction threshold, so that the triggering of the power reduction processing can be controlled. For example, in a TDMA network, a receiving node may calculate a reception duration, may align the expiration of the reception duration with the slot boundaries of the TDMA, and may compare the size relationship between the reception duration and a preset threshold. Optionally, the duration of the reception is assumed to be 30ms, and the preset threshold is assumed to be 20ms, so that the duration of the reception is longer than the preset threshold, and the operation of power consumption reduction processing of the node can be triggered, thereby reducing the power consumption of the node. Specifically, it is assumed that the preset thresholds are respectively: presetting an electrical threshold, presetting an off clock threshold and presetting a step-down (frequency-down) threshold, wherein the power consumption reduction processing can be as follows: when the continuous time length of the receiving is longer than a preset power-off threshold value, turning off a power supply of hardware on a receiving channel, and turning off an electrode to save electricity; when the continuous time length of the receiving is longer than a preset clock closing threshold value, closing a clock of hardware on a receiving channel, and performing clock gating power saving; when the continuous time length of the receiving is longer than a preset voltage-reducing (frequency-reducing) threshold value, the clock frequency of hardware on a receiving channel is reduced, and clock frequency-reducing and power-saving are performed. The hardware on the receiving channel and the hardware on the transmitting channel respectively belong to an independent power domain and a clock domain, and the power consumption reduction processing can be independently carried out when the receiving and the transmitting are terminated.
In some embodiments, after the control node power down process ends, the hardware on the receive channel may be restored to an idle state, ready for the next round of data reception and transmission. For example, for TDMA/CSMA half duplex systems, if power consumption is reduced for both the hardware on the receive channel and the hardware on the transmit channel, the receive-transmit control module restores both the hardware on the receive channel and the hardware on the transmit channel to an idle state, ready for the next round of data reception and transmission.
The critical value of the duration of the receiving can be determined through the preset threshold value, and the power consumption reduction processing of the node can be controlled when the duration of the receiving is longer than the preset threshold value, so that the power consumption of the receiving and transmitting of the node can be accurately reduced.
In some embodiments of the present invention, analyzing data to be identified, extracting to obtain target identification information and a receiving duration, including:
the start of frame field of the data to be identified is extracted. Wherein the frame start field may be a frame header start portion of the data to be identified. Optionally, the frame structure of the data to be identified is an L1/L2 protocol frame structure, and the receiving duration and the target identification information may be stored in a designated position of a frame header start portion (i.e., a frame start field) of the L1 or L2 frame, so that the receiving duration and the target identification information may be received in preference to other fields, and thus may be identified and parsed by the receiving node in preference to other fields.
And analyzing the frame start field, and extracting target identification information and receiving duration according to the analysis result. And the receiving node which can analyze the analysis result can analyze the frame start field to obtain the result. Optionally, the receiving duration and the target identification information may be stored in the frame start field, so that when the receiving node receives the data to be identified, the frame start field may be rapidly parsed, and thus a parsing result may be obtained, that is, the target identification information and the receiving duration may be obtained. By analyzing the frame start field of the data to be identified, the data to be identified can be analyzed rapidly, and the identification efficiency is improved.
In some embodiments of the present invention, the extracting the receiving duration according to the parsing result includes:
and extracting the frame length in the frame start field according to the analysis result. The frame length may be the length of each frame when the data to be identified is compressed. Alternatively, the parsing result may include a frame length or a frame transmission duration, and if a field in the frame header is a frame length instead of the frame transmission duration, the frame length may be extracted, and the reception duration may be calculated according to the frame length.
Transmitter performance information, receiver performance information, and index information are obtained. Wherein the transmitter performance information may be information indicating the performance of the transmitter; the receiver performance information may be information indicating the performance of the receiver; the index information may be an MCS (Modulation and Coding Scheme ) index value. Alternatively, the transmitter performance information, receiver performance information, and index information may be used to calculate the receive duration.
The frame length is converted to a reception duration based on the transmitter performance information, the receiver performance information, and the index information. Alternatively, assuming that the index information may be an MCS index value, the frame length may be converted into a reception duration according to information such as a transmitter performance, a receiver performance, an MCS index value, etc., for example, into a reception duration and a transmission duration, thereby obtaining the reception duration. The frame length is converted into the receiving duration according to the transmitter performance information, the receiver performance information and the index information, so that the data to be identified can be identified efficiently.
In some embodiments of the invention, prior to the data to be identified, comprising:
a local synchronization sequence is acquired. The local synchronization sequence may be a synchronization sequence corresponding to a node. Alternatively, since different nodes correspond to different local synchronization sequences, the local synchronization sequence corresponding to the receiving node may be acquired.
And acquiring a preamble field of the data to be identified, and extracting according to the preamble field to obtain a receiving synchronization sequence. The preamble field may be preamble information in a frame structure of the data to be identified; the received synchronization sequence may be a synchronization sequence in a frame structure of the received data to be identified, which may be stored in a preamble field. Optionally, the preamble field of the data to be identified may be parsed, and the receiving synchronization sequence may be extracted.
And controlling to receive the data to be identified based on the receiving synchronous sequence, and acquiring the data to be identified if the receiving synchronous sequence is the same as the local synchronous sequence. Optionally, the receiving synchronization sequence and the local synchronization sequence may be compared, that is, whether the data to be identified to be received is the data sent to the node is judged, and if the receiving synchronization sequence is consistent with the local synchronization sequence, the data to be identified may be the data sent to the node, so that the data to be identified may be obtained. Optionally, if the receiving synchronization sequence is inconsistent with the local synchronization sequence, it may be determined that the data to be identified is not data sent to the node, and the receiving of the data to be identified may be stopped, so that hardware on the receiving channel is restored to an idle state, so that the next round of data receiving and sending is performed. By comparing the local synchronous sequence with the receiving synchronous sequence and judging whether the data to be identified is the data which needs to be received by the node, the data identification efficiency can be improved.
