Description

 Network node configuration information processing method, network node, and communication system The application is filed on September 30, 2009, and the application number is 200910179576. 8 , and the invention name is "network node configuration information processing method, network node, and communication system" Priority of the Chinese application, the entire contents of which are incorporated herein by reference. Technical field

 The present invention relates to the field of communications, and in particular, to a network node configuration information processing method, a network node, and a communication system. Background technique

 Wireless sensor network is a widely used wireless network, and can adapt to a variety of realistic intelligent environments. Wireless sensor networks have been rapidly developed, and are self-organizing, self-managing, self-energy-saving, high reliability, and low cost. And suitable for harsh environments, it is widely used in military, medical, environmental protection and transportation.

Wireless sensor networks can use non-beacons to enable networks and beacons to enable networks. In a non-beacon-enabled network, devices do not periodically transmit beacons, and communication between devices is generally asynchronous. The beacon enables the network to organize communication between devices in the wireless sensor network in a superframe period. The superframe structure mentioned above is composed of a beacon period, a channel contention access period (hereinafter referred to as CAP), and a content i on Free Period (CFP) and The inactive period consists of a specific format defined by a coordinator that specifies a superframe, wherein the beacon period, the channel contention access period, and the channel non-competition period constitute an active period of the superframe. The active period includes 16 equal-sized time slots, wherein the beacon frame is transmitted in the first time slot of the superframe, and each superframe period starts with a beacon frame sent by the network coordinator, in the beacon frame. It includes information such as the duration of the superframe period, the overall structure of the superframe, the arrangement of each phase, and the time synchronization of each device. After receiving the beacon frame, the device in the network completes the network synchronization according to the information therein and clarifies whether the device undertakes the data communication task in this super frame period. After the communication of the channel competition access period of the superframe ends, the network enters a non-competition period for ensuring the communication service between the devices. The communication at this stage is a guaranteed time slot (Guaranteed T s, hereinafter referred to as GTS). The component network coordinator sets a communication time period consisting of a channel-free time slot in the superframe structure to ensure the synchronization and independence of the device communication service. The general GTS appears at the end of the active superframe, and each GTS typically occupies one or more time slots. Each device that passes the GTS must ensure that its transaction is completed before the next GTS arrives. A superframe can include several guaranteed slots, and each device assigned a guaranteed slot must guarantee its communication before the next guaranteed slot arrives. carry out. After completing the active phase of the device, the devices in the wireless sensor network will go to sleep to save energy, waiting for the next superframe period to arrive.

 In the existing network communication, each device can complete the guaranteed time slot communication on multiple channels by frequency hopping. This communication method, that is, Enhanced Guaranteed Time Stream Communication (hereinafter referred to as EGTS), can expand the communication capacity of the network system. Extended guaranteed time slot communication not only allocates time slot resources, but also allocates channel resources to enable different devices to communicate at different times and channels. In the extended guaranteed time slot communication, the resource information of the time slot and the channel are both present in the configuration bit chart (hereinafter referred to as ABT). In EGTS communication, ABT is a two-dimensional table of the recording channel and time slot resource usage status stored in each node. The table is dynamically updated as the node itself and neighboring neighbors apply for and release the EGTS. The specific configuration bit chart can be as shown in the following table:

The ABT shows 7 time slots (s lo t ) x 9 channel usage in an EGTS, where each time slot and channel is represented by one bit, G represents that the resource is not occupied, and 1 represents the resource is occupied. use. So ABT is a two-dimensional table containing different bit information.

 In the communication using the EGTS mode, if the network node sends data to the network node 2, it can apply to the network node 2 to use a time slot and channel resources in advance. After the resource application is successful, the network node will use its own ABT. The corresponding bit of the resource is identified as 1. After the resource is used up, the network node 1 and the network node 2 release the resource, and the corresponding position in the respective ABT is identified as 0. The network node in the prior art cannot modify the corresponding ABT resource identifier in time. As the network running time increases, this situation will gradually accumulate, which will cause the information in the ABT table to be inconsistent with the actual resource usage of the network, affecting the normal operation of the network. Summary of the invention

 The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

 The technical solutions in the embodiments of the present invention are described below with reference to the accompanying drawings and embodiments.

 In some common communication networks, such as in networks using EGTS communication, each network node maintains a corresponding ABT that records the network node itself and the resources used by neighboring nodes (including channels and time slots). . The neighboring nodes in the embodiment of the present invention refer to network nodes in the range of one hop. Since the neighboring nodes of different nodes are not completely the same, even the ABT of each network node is not exactly the same.

FIG. 1 is a schematic flowchart of a method for processing network node configuration information according to an embodiment of the present invention. As shown in FIG. 1, the method includes the following steps: The resource operation information is used to identify that the foregoing resource has been released or occupied; the resource operation in this step may specifically include a resource release operation and a resource occupation operation, that is, when the source node has data to send to the target node, the source node Sending a resource request message to the target node to acquire a resource of a channel and a time slot. After receiving the resource request message, the target node allocates a resource, and sends a broadcast message including resource occupation information to the source node and the neighboring node, and notifies the foregoing. The allocated resources are already occupied. In the process, the source node and the target node both store the resource occupation information corresponding to the occupied resources. In addition, at the end of the data transmission, the source node sends a message requesting to release the occupied resources to the target node, and the target node is released. Corresponding resources, and sending a broadcast message including resource release information to the source node and other neighboring nodes, notifying that the allocated resource has been released, in which both the source node and the target node store the resource release information corresponding to the released resource. ;

 Step 102: If the configuration bit map information included in the received broadcast information of the first neighboring node is inconsistent with the stored resource operation information, send, to the first neighboring node, the resource operation information. And a notification message for notifying that the resource has been occupied or released, so that the first neighboring node modifies corresponding resource operation information.

 It can be seen that the source node and the target node both store the resource release information corresponding to the resource release operation and the resource occupation information corresponding to the resource occupation operation, that is, which resources are occupied by themselves or which resources are released by themselves. When the source node or the target node receives the broadcast message from the first neighboring node, the configuration bit chart information carried in the broadcast message is obtained, and the configuration bit chart information is usually the configuration of the first neighboring node that sends the broadcast message. A part of the bit chart, the source node or the target node queries whether the resource release information or the resource occupation information stored in the network node is consistent with the information of the corresponding resource in the configuration bit chart information. If they do not match, the notification message corresponding to the resource operation information is sent to the first neighboring node.

Specifically, when the configuration bit map information included in the broadcast information is inconsistent with the resource release information stored by the source node or the target node itself, the foregoing information is sent to the first neighboring node corresponding to the resource operation information, and is used to notify the The notification message that the resource has been occupied or released includes: the source node or the target node sends a resource release notification message to the first neighboring node, the resource release notification message Including information that the above resources have been released;

 The network node (including the source node and the target node) in the foregoing embodiment of the present invention stores corresponding resource operation information when resource operation occurs, and configures bitmap information included in the received broadcast information of the first neighboring node. When the resource operation information stored in the self is inconsistent, the corresponding notification message is sent to notify the first neighboring node that the occupied information of the recorded resource is inconsistent with the local network node, so that the first neighboring node performs processing. With the above technical solution of the present invention, it is possible to effectively solve the technical problem caused by the unreliability of the broadcast message sent to the neighboring node when the source node and the target node occupy or release the resource, and operate the resource stored by the source node or the target node. When the information is inconsistent with the storage of its neighboring nodes, it can be further verified and adjusted to effectively improve network performance and achieve normal network operation.

On the basis of the foregoing embodiment, if the first neighboring node receives the resource occupation notification message, the first neighboring node correspondingly modifies the value of the bit corresponding to the occupied resource in the configuration bit map configured by itself; or the first neighbor After receiving the resource release notification message, the node queries whether the resource is occupied by the first neighboring node or whether the resource is occupied by a second neighboring node adjacent to the first neighboring node, and further, in the When the resource is occupied by the first neighboring node, the first neighboring node sends a response message to the source node or the target node including information indicating that the resource is occupied by the first neighboring node; or When the second neighboring node is occupied, the first neighboring node sends a response message including information indicating that the resource is occupied by the second neighboring node to the source node or the target node; or the resource is not the first When an adjacent node occupies and is not occupied by the second neighboring point, the first neighboring node modifies a bit corresponding to the resource in the configuration bit map of the configuration, Transmission to the destination node or the source node have been modified in their respective positions chart owned configuration bits The response message of the source's flag bit.

 In addition, the foregoing embodiment may further include: when the source node or the target node receives the response message indicating that the resource is occupied by the first neighboring node, the bit corresponding to the resource in the configured configuration bit chart. The value is modified to a value indicating that the resource is already occupied.

Regarding the function of the system, reference may be made to the description of the foregoing method embodiments.

 The following is a specific embodiment of the present invention. As shown in FIG. 6, when the network node A (source node) requests to release the previously applied EGTS resource from the network node B (target node), the network node A sends an EGTS to the node B. Reques t (EGTS request) command frame, the command frame contains part of the ABT information that needs to be released, and the network node B receives the release request of the network node A, that is, the EGTS Reques t (EGTS request) command frame, and will be its own ABT. The information is compared with part of the ABT information carried in the command frame, the corresponding time slot and channel resources are released, and a response broadcast EGTS Reply command frame is sent to announce to the neighboring node that the resource has been released. The one-hop range node around the network node B includes the network node A to receive the broadcast information, and the node around the network node B, such as the network C node, also knows that the node B has released a certain time and channel resources, and will be based on the broadcast information. The ABT table released in the user updates its own ABT, and identifies the resource occupied by the network node B as 0, so that the resource can be used for communication in the subsequent communication process. At the same time, the network node B records the release operation in the device, that is, the resource operation information in the above embodiment of the present invention, and the record is saved until the released resource is re-occupied by other network nodes or itself. After receiving the response broadcast message from the network node B, the network node A also updates its own ABT and broadcasts the EGTS No ti fy (EGTS notification) command frame to announce to the neighboring nodes of the network node A that it has already The resource was released. At the same time, network node A will record the operation, and the record will be saved until the released resource is re-occupied by other network nodes or itself. In this way, the release operation is recorded in both the receiving and transmitting nodes, and the necessary information is provided for subsequent comparison of ABT resources.

When the network node A (or the network node B, here taking the network node A as an example) receives the neighboring node, for example, the network node D issues information related to the ABT, for example, listening to the network node D Broadcast information such as EGTS Rep ly (EGTS response) or EGTS Not i fy (EGTS notification) will compare the ABT information contained in the broadcast information with its own release operation record (ie, resource operation information) while modifying its own ABT. If it is found that the resource that has been released by the network node A itself is marked as occupied in the ABT of the network node D, the network node A understands that the network node D has not received its own broadcast message releasing the resource, and thus "good faith" Unicasting a data packet to the network node D, that is, the resource release notification message mentioned in the above embodiment, prompts the network node D that the resource has been released by the network node A. After receiving the prompt information, the network node D queries to determine whether the resource is being occupied by itself or an adjacent node without being released. It can be understood that the neighboring nodes of the network node D and the neighboring nodes of the network node A are not completely identical. If the resource is occupied by the network node D itself, the reply network node A is in use by the network node D, and the network node A as the neighboring node should mark the area resource identifier after receiving the information. If the network node D is not occupied by itself but is occupied by other neighboring nodes of the network node D, and the response message is returned to the network node A, and the resource is reasonably occupied, the network node A does not receive the response message. Modifications to its own ABT, unless the neighboring nodes of network node A and network node B occupy the above resources; if there is no record indicating that the above resources are in a reasonable occupied state, it indicates that the resource is due to network node D not listening to the network. The broadcast message sent by the node A is left behind, so the bit corresponding to the resource in the ABT of the network node D is released and cleared to indicate that the resource is in an idle state, and is sent to the network node A already in the ABT. The corresponding bit of the above resource is used to release a clear response message.

When the network node A unicasts a data packet to the network node D, that is, the resource release notification message mentioned in the foregoing embodiment, the frame structure of the data packet may be as shown in FIG. 7, and may include a frame header of seven sub-sections. a 1-byte command identifier, and a variable (ie, load), wherein the frame header may include address information of the network node A, and the command identifier is used to indicate that the data packet is a unicast query frame, and the variable includes the network node A. The record is released, and the information of the occupied resource is recorded in the ABT information included in the broadcast information sent by the network node D, that is, a corresponding bit to be confirmed in the ABT list, and other related information. In the ABT list, resources are occupied or available for free. The bit indicates that 1 means that the resource is occupied, and 0 means that the resource is idle.

 After receiving the above data packet, the network node D queries the relevant ABT resource occupied by itself, and if the relevant ABT resource is occupied by the network node D itself, the information is fed back to the network node A to notify the network. Node A is the resource that the network node D is using, and also needs the network node A to identify that the resource is used on the ABT table; if the related ABT resource is occupied by the neighboring node of the network node D, the network node D feeds back Network node A—a response message indicating that the resource is used by its neighboring nodes, and network node A does not need to do any processing; for example, the above resources are neither occupied by network node D nor by other nodes of network node D. If the neighboring node is occupied, the resource may be determined to be a legacy resource that is not released. Then, the network node D performs a release operation, and the information corresponding to the resource in the configured configuration bit chart is modified, that is, the value of the corresponding bit is set to zero. To indicate that the resource is idle on the ABT table, and send the network node including the network node D has modified the response message of the value of the bit corresponding to the resource in the configured configuration bit map.

 Through the above query and comparison process, the network node can effectively clear the ABT resources of the neighboring nodes through the operation records in the ABT, and release more available channels and time slot resources.

The storage of resource operations can also be used in the resource application process of the EGTS. As also shown in Figure 6, network node A applies for EGTS resources to network node B, network node B issues EGTS Repl y broadcast frames, and node A continues to issue EGTS Not i fy broadcast frames. Node A and Node B will record the resource request operation and related ABT resources. In the subsequent communication process, the network node A or the network node B listens to the ABT resources in the EGTS-related broadcast frames of the neighboring nodes, and compares with the stored resource operation records, and finds that the EGTS resources that have been applied for are not around. The identifiers in the ABTs advertised by other neighboring nodes send a message to the network node that issues the EGTS-related broadcast frame, notifying the network node that the related resources have been occupied by itself, and the neighboring nodes need to identify the relevant bits as Occupy sign.
