Description

METHOD AND SYSTEM FOR PROVIDING ADAPTIVE CREDIT IN WIRELESS COMMUNICATION NETWORK}

The present invention relates to a method and system for providing adaptive credit in a wireless communication network for adaptively providing credit to a mobile node relaying a signal of a wireless AP constituting a mobile adhook network.

Mobile ad hoc networks primarily use IEEE 802.11 wireless networks, which are now widely used in a variety of mobile devices, including notebooks and cell phones. In particular, since mobile devices such as mobile phones have a flexible distance from the currently communicating wireless access point (AP), the signal strength is easily weakened, so communication with the wireless AP is easily broken. At this time, if there are no other wireless APs available nearby or no mobile device relays the wireless AP signal, the wireless network cannot be used.
In addition, the range of communication with the wireless AP varies depending on the manufacturer, but it supports stable communication within an average maximum distance of 50m for general use and 200m for outdoor use for corporate use. In such an environment, it is impossible to travel with a mobile device outdoors and use a wireless network, unless the wireless APs are arranged at narrow intervals.

In order to overcome the limitations of the mobile wireless network environment between the mobile device and the wireless AP, a lot of research has been conducted and actual technologies are being developed. The technologies developed in this way are divided into focusing on improving the transmission / reception distance of the wireless AP and focusing on the relay technology of the mobile device. Among the former, there is a problem that many users cannot easily access and benefit from the subscription fee to use the service providing the technology, and the latter technology is mostly included in the mobile ad hoc network.

       The mobile ad hoc network is an ad hoc method in which mobile devices are directly connected without going through a wireless AP. The mobile ad hoc network uses a Bluetooth standard or a Wi-Fi standard as a network of mobile devices. In addition, Wi-Fi chipsets are included in most devices, making them very versatile.

       The basic relay operation of the mobile ad hoc network is shown in FIG.

If the mobile device 104 is located outside the transmit / receive range of the wireless AP 100 and cannot use the wireless network, and the mobile device 102 close to the mobile device 102 is located within the wireless AP 100 range, the mobile device 102 is the wireless AP 100. By relaying the signal, the mobile device 104 can use the wireless network.

       This relay operation is limited to a specific situation in which a mobile device within a radio AP's transmit / receive range needs to relay a signal to another mobile device. Also, the dual use of Wi-Fi resources reduces bandwidth and increases the power consumption, which is the main point of the mobile device. It means giving a signal to other devices while taking the risk. These points are accentuated as the mobility of mobile ad hoc networks increases.

      Therefore, as long as the above problems exist, users mean that they have no reason to use the mobile ad hoc network while wasting resources of their mobile devices.

Accordingly, an aspect of the present invention is to provide an adaptive credit providing method and system in a wireless communication network for inducing a user to voluntarily perform a relay operation using credit in a mobile ad-hook network.

According to an aspect of the present invention, in a method for providing adaptive credit in a wireless communication network, a neighboring access point (AP) in the wireless communication network is searched to form a communication link with an AP corresponding to an optimal signal strength. Forming a relay node network by forming a transmission path between the linked AP and neighboring mobile nodes, performing a signal relay between at least one neighboring mobile node and the AP, and performing a wireless communication network And searching for a relay mobile node that transmits and receives a frame through a wireless channel to the AP and at least one mobile node, and provides credit to the found relay mobile node.

According to another aspect of the present invention, in an adaptive credit providing system in a wireless communication network, a neighboring access point (AP) in the wireless communication network is searched to form a communication link with an AP corresponding to an optimal signal strength. And a host mobile node for forming a relay node network by forming a transmission path between the linked AP and neighboring mobile nodes, and performing signal relay between at least one neighboring mobile node and the AP, within the wireless communication network. First and second slave mobile nodes which select a mobile node other than themselves as their AP signal relay mobile node, and transmit and receive data frames with the AP through the relay mobile node; Search for relay mobile nodes that transmit and receive frames over a wireless channel to one or more mobile nodes, and A retrieved relay mobile node, characterized in that it comprises a service server that provides credit (Credit).

According to the present invention, a user using a wireless ad hoc network voluntarily participates in a communication network based on a credit policy for overcoming a waste of radio resources due to a relay. It is effective in overcoming the limitations of relaying.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It will be appreciated that those skilled in the art will readily observe that certain changes in form and detail may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims. To those of ordinary skill in the art.

The present invention relates to a wireless personal area network (WPAN) wireless ad hoc network including a plurality of piconet zones in which at least one mobile node is present. If the transmission speed is too slow or communication is impossible, the relay mobile node can be used to improve the transmission speed and expand the area, and in this process, credit can be used to allow the user to voluntarily act as the relay mobile node. By inducing the user to use the wireless ad hoc network, the user voluntarily participates in the communication network based on the credit policy of overcoming the waste of radio resources due to the relay, thereby allowing the distance problem and the spontaneous relay of the wireless AP within the wireless ad hoc network. To provide a technique to overcome the limitations.

In addition, examples of the mobile node digital broadcasting terminal, a personal digital assistant (PDA), a smart phone, a tablet PC, an iPad, and a 3G terminal according to an embodiment of the present invention. For example, all information communication devices such as International Mobile Telecommunication 2000 (IMT-2000) terminals, Wideband Code Division Multiple Access (WCDMA) terminals, Global System For Mobile Communication Packet Radio Service (GSM / GPRS), and Universal Mobile Telecommunication Service (UMTS) terminals. And multimedia devices. However, it will be readily apparent to those skilled in the art that the configuration according to the embodiments described herein may also be applied to fixed terminals, such as digital TVs, desktop computers, and the like, except where applicable only to portable terminals.

In addition, IEEE 802.11 is a standard that defines a medium access control (MAC) layer protocol and a physical layer standard for implementing WLAN. Products are widely used.

The standard is limited to the LAN, and although the maximum communication distance is not specifically specified, it is generally recognized to cover a short distance of about 100 meters. It uses a common frequency in the 2.4 GHz band, called the Industrial Scientific Medical (ISM) band, or the 5 GHz band, called the Unlicensed National Information Infrastructure (U-NII) band in the unlicensed band, so that the maximum transmit power in these bands varies from country to country. Restrict.

On the other hand, the data transmission rate defined by the IEEE 802.11 standard is divided into several stages from 1Mbps to 54Mbps according to the modulation and demodulation method, and a plurality of data rates are used simultaneously. This means that each data packet can be sent at a different rate. In general, the transmission speed and distance are inversely proportional, so when the destination is near, the transmission speed is high and the distance is low speed.

Therefore, in case of a mobile node that is far from the AP or an obstacle exists in a radio path, data is always transmitted and received at a slow speed, and a mobile node in close proximity can exchange data at a high speed so that an unfair situation occurs. Done. In addition, while transmitting and receiving data between any two mobile nodes or APs, other mobile nodes in the service area must also be rested. Therefore, if there are many mobile nodes with slow transmission speeds, the transmission efficiency of the entire network is deteriorated.

Hereinafter, in an embodiment of the present invention, one of the mobile nodes that communicate by forming a direct one-to-one communication link with an AP in a wireless communication network is set as a host mobile node, and is located in the periphery of the host mobile node. Note that the mobile node relaying the AP signal from the mobile station is configured as a first or second slave mobile node.

Hereinafter, an adaptive credit providing method in a wireless communication network according to an embodiment of the present invention will be described in detail with reference to FIG. 2.

2 is a schematic flowchart of an adaptive credit providing method in a wireless communication network according to an embodiment of the present invention. Referring to FIG. 2, in step 210, the host mobile node 202 searches for APs around the wireless communication network and forms a communication link with an AP corresponding to an optimal signal strength.

In this case, the wireless communication network uses a multi-hop transmission technology using a repeater, and based on the maximum transmit power, signal-to-noise ratio, etc. Based on the Status Factor, the host mobile node 202 provides the AP search corresponding to the optimal signal strength.

Therefore, in step 212, the AP is searched based on the maximum transmission power and the signal-to-noise ratio among the APs located in the wireless communication network, and if it is satisfied, the process moves to step 214, and if it is not satisfied, the process is repeated repeatedly. .

In step 214, the host mobile node 202 establishes a link with the discovered AP 200, and in step 216, forms a transmission path between the linked AP 200 and the neighboring mobile nodes 204 and 206 to relay. Form a node network.

Here, the host mobile node 202 and the surrounding mobile nodes 204 and 206 of the host mobile node use a low-modulation modulation and demodulation scheme without a separate external power source, and have a single antenna or a simple scheme in which the radiation pattern is not freely changed. Antenna arrays can be used.

In addition, the relay node network is formed in the wireless communication network in which the host mobile node 202 has a one-to-one link with the AP 200 and neighboring mobile nodes, that is, the first slave mobile node 204 and the second slave mobile node 206. ) To establish a relay node network by forming a transmission path between neighboring mobile nodes 204 and 206 in a predetermined network structure in order to perform layer division and to perform a signal relay role therebetween.

The radio wave transmission area between the mobile nodes included in the relay node network includes an operation area of the entire wireless communication network, and a mobile node requesting a link formation within 1-hop with the one AP is set as a host node. A mobile node that is slaved to a host node and directly or via an AP signal is configured as a slave node of the host node.

In this case, the radio wave transmission area of the relay node network is preferably arranged to cover the entire operating area of the entire wireless communication network.

Subsequently, in step 218, the host mobile node 202 performs routing from the routing table to the AP 200 and the neighboring mobile nodes 204 and 206 when a signal is relayed between the AP 200 and the neighboring mobile nodes 204 and 206. Distinguish.

Here, the routing table may include a mask, a destination address, a next-hop address, a flag, a reference count, a use, and an interface. The mask is used to verify the destination network address and the sub network address. The network address is calculated using the mask address.

The destination address indicates a destination host address in the case of host-specific routing, and a destination network address in the case of network-directed routing.

The next hop address indicates only the address of the next path of the packet transmission path.

The host mobile node 202 in the wireless communication network searches for an optimal path using the routing table as the destination address of the received packet.

In operation 220, a virtual interface architecture (VIA) is formed for each of the AP 200 and the neighboring mobile nodes 204 and 206. The VIA is a lightweight communication interface standardized by US computer companies such as Microsoft, Compaq, and Intel, and can transmit and receive messages at the user level without the help of a kernel.

Here, referring to FIG. 3, FIG. 3 shows host mobile nodes 306 and 314 around APs 312 and 304 located in a wireless communication network and peripheral mobile nodes 308 and 310 linked to the respective host mobile nodes. , 316, the relay node network 302, 311, wherein the 311 relay node network includes a host mobile node 306 linked with the AP 304 in a 1-hop peripheral mobile node 308, 310; In the 302 relay node network, a host mobile node 314 linked with an AP 312 is connected to peripheral mobile nodes 310 and 316 in one-hop to form the wireless communication network.

Each of the mobile nodes 306, 308, 310, 314, and 316 included in each of the relay node networks 302 and 311 includes a WiFi chipset and is configured to perform STA (AP-Station) method for wireless AP signal relay. After being connected to the wireless AP by the STA method, a virtual interface adopting the AD-HOC method is generated to communicate with neighboring mobile nodes.

2, the host mobile node 202 performs signal relay between the AP 200 and the neighboring mobile nodes 204 and 206.

In this case, the first slave mobile node 204 and the host mobile node 202 that are slaved by directly receiving an AP signal from the host mobile node 202 relaying the AP 200 signal from the host mobile node 202. And a second slave that receives and receives a data frame of the AP signal sequentially through the neighboring mobile nodes of the slave.

One of the first slave mobile node 204 and the second slave mobile node 206 relays the AP 200 signal from a neighboring mobile node or relays the relayed signal to another neighboring mobile node. .

The relay function node is selected by calculating the transmission efficiency according to the relay signal transmission through the peripheral mobile node, that is, the first slave mobile node 204 and the second slave mobile node 206.

In step 224, the service server 208 searches for a relay mobile node that transmits and receives a frame through a wireless channel to the AP 200 and the at least one mobile node in the wireless communication network.

At this time, the relay server search in the wireless communication network in the service server 208 is performed by detecting the source address and the destination address from the header of the packet for each mobile node in the wireless communication network.

That is, in step 226, the source address and the destination address are extracted from the header of each packet formed for each mobile node in the wireless communication network. In step 228, the transfer path for each address of the extracted mobile node is the MAC address of the mobile node. And if the destination address corresponds to the AP, and if not, go to step 224 to continuously perform the relay mobile node search, and if so, go to step 230 to perform the search. Credits are provided to mobile nodes 202 and 204.

Here, referring to FIG. 4, FIG. 4 includes a host mobile node 402 centered around an AP 400 located in a wireless communication network and peripheral mobile nodes 404 and 406 linked to each of the host mobile nodes. In the relay node network, a credit provision target mobile node and a packet from a service server are shown together with a table, and the credit provision target mobile node in the wireless communication network corresponds to 402 and 404 from the service server in the relay node network. Among them, packets 2, 3, and 4 of the 402 mobile node and packets 2 and 4 of the 404 mobile node correspond to this.

In the credit providing packet, a packet and a source address (SRC) whose forwarding path source address (SRC) is different from its MAC address, or whose destination address (DST) is an AP, extracted from the header for each packet of the tables shown in 402 and 404, respectively. Is an AP and the destination address (DST) is different from its MAC address.

At this time, when the credit is provided by the service server, a predetermined mobile node randomly selects a mobile node that performs signal relay with the same MAC address to the same MAC address in excess of a communication amount set within a predetermined period or time for credit acquisition, and provides credit. Control over is performed.

More specifically, referring to FIG. 5, FIG. 5 illustrates a host mobile node 502 centered around an AP 500 located in a wireless communication network and peripheral mobile nodes 504, 506, and 508 linked to each host mobile node. In a predetermined relay node network constituted by), a credit provision target mobile node and a packet from a service server are shown together with a table.

Any mobile node may acquire multiple credits by continuously relaying wireless AP signals to the same mobile node, and use the MAC address, which is a unique number of the wireless network card, to block these unintended credit attempts. This can prevent abuse by placing an upper limit on the credit provision for relaying signals to the same MAC address within a certain period or time, such as a day or a week.

FIG. 5 illustrates such a credit capping technique. In the respective tables 503, 505, 507, and 508 of each mobile node 502, 504, 506, and 508, the MAC address of the source node and the number of packets are shown in parentheses. The number within indicates the credit received. In FIG. 5, the upper limit of credit provision for each node is 300, and the 508 mobile node is present in the relay node network of the wireless communication network, and relays signals through the 506 and 504 mobile nodes before moving. The number of packets relayed by the 506 mobile node is 250, the number of packets relayed by the 504 node is 10, the number of packets relayed by the 508 mobile node is 460, and the number of packets relayed through the 506 and 504 nodes is 460. At this time, credits are provided from the service server by the number in parentheses.

In this way, an upper limit of credit provision for each relay node is set in advance, and the provided credit is stored in a predetermined mobile node and a service server to set a user access authority level.

The stored credit requests and relays the AP signal from the neighboring mobile node when it is impossible to establish a link within 1-hop with the AP. It is used at the time of use, or as a point charging on the credit providing service server side by consuming the credit.

In this case, the wireless data communication amount generated by either one of the first slave node and the second slave node receives an AP signal and a value generated when using a direct wireless network communication relays the AP signal to another neighboring mobile node. It is larger than the value generated at the time, and stored credits are not consumed when relaying the AP signal to the neighboring mobile nodes.

Here, the pseudo code for the credit providing method from the service server at the time of relaying is provided based on the algorithm shown in FIG. 6 (a), and the credit consumption of the mobile node relaying the AP signal is determined by the algorithm shown in FIG. 6 (b). I use it.
