Description

Network node configuration information processing method, network node and communication system

technical field

The embodiments of the present invention relate to the technical field of communication, and in particular to a method for processing network node configuration information, 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 real intelligent environments, wireless sensor network has been developed rapidly, and with its self-organization, self-management, self-energy saving, high reliability and low cost And suitable for harsh environments and other characteristics, it is widely used in military, medical and health, environmental protection and transportation and other fields.

Wireless sensor networks can employ both non-beacon-enabled networks and beacon-enabled networks. In non-beacon enabled networks, devices do not periodically send beacons, and communication between devices is generally asynchronous. In the beacon-enabled network, the superframe is used as the period to organize the communication between devices in the wireless sensor network. The above-mentioned superframe structure consists of the beacon period, the channel contention access period (Contention AccessPeriod, hereinafter referred to as: CAP), and the channel without contention The time period (Contention Free Period, hereinafter referred to as: CFP) and the inactive period are composed, and its specific format is defined by the coordinator who specifies the superframe. active period. This active period includes 16 time slots of equal size, in which the beacon frame is transmitted in the first time slot of the superframe, and each superframe period starts with the beacon frame sent by the network coordinator, in the beacon frame It contains information such as the duration of the superframe period, the overall structure of the superframe, the time arrangement of each stage, and the time synchronization of each device. After receiving the beacon frame, the devices in the network complete network synchronization and clarify whether the device undertakes data communication tasks within this superframe period according to the information in it.

After the communication in the channel competition access period of the superframe ends, the network enters the channel non-competition period to ensure the communication service between devices. The communication in this stage is composed of guaranteed time slots (Guaranteed Time Slot, hereinafter referred to as: GTS) to form network coordination The device sets a part of the communication time period composed of channel-free period slots in the superframe structure to ensure the synchronization and independence of device communication services. Generally, a GTS appears at the end of an active superframe, and each GTS generally occupies one or more time slots. Each device that transmits a GTS must ensure that its transaction is completed before the arrival of the next GTS. A superframe can include several guaranteed time slots, and each device that is allocated a guaranteed time slot must ensure that its communication is before the arrival of the next guaranteed time slot Finish. After completing the device active phase, the devices in the wireless sensor network will go to sleep to save energy and wait for the arrival of the next superframe period.

In the existing network communication, each device can complete guaranteed time slot communication on multiple channels through frequency hopping. The communication capacity of the network system. Extended guaranteed time slot communication not only allocates time slot resources, but also allocates channel resources, so that different devices can communicate at different times and channels. However, this communication method will lead to resource allocation. The requirements are more complex. In the extended guaranteed time slot communication, the resource information of the time slot and the channel exists in the allocation bitmap (Allocation Bitmap Table, hereinafter referred to as: ABT). In extended GTS communication, ABT is a two-dimensional table that records the usage status of channel and time slot resources stored inside each node. The table is dynamically updated according to the application and release of EGTS by the node itself and surrounding neighbor nodes. The specific configuration bitmap can be shown in the following table:

0 1 2 3 4 5 6 7 8 Slot1 0 1 1 0 0 0 0 0 0 Slot2 1 0 0 0 0 0 0 0 0 Slot3 0 0 0 0 0 0 0 0 0 Slot4 0 0 0 0 0 0 0 0 1 Slot5 1 0 1 1 0 0 0 1 0 Slot6 0 0 0 0 0 0 0 0 0 Slot7 0 0 0 0 0 1 0 0 0

The ABT shows the usage of 7 slots x 9 channels in an EGST, where each slot and channel is represented by a bit, 0 means that the resource is not occupied, and 1 means that the resource is occupied. So ABT is a two-dimensional table containing different bits of information.

In the communication using EGTS mode, if network node 1 has data to send to network node 2, it can apply to network node 2 for a time slot and channel resource in advance. The bit corresponding to the resource is identified as 1. After the resource is used up, the network node 1 and the network node 2 release the resource, that is, mark the corresponding position in their respective ABTs as 0.

In the process of realizing the present invention, the inventor finds that in the prior art, the network node cannot modify the corresponding ABT resource identifier in time. With the extension of network operation time, 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.

Detailed ways

The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

In some common communication networks, for example, in the network using DGTS communication mode, each network node will save the corresponding ABT, which records the resources (including channels and time slots) used by the network node itself and adjacent nodes . Adjacent nodes in the embodiments of the present invention refer to network nodes within a hop range. Since the adjacent nodes of different nodes are not completely the same, the ABTs of each network node will not be completely the same even if they are adjacent nodes.

Fig. 1 is a schematic flowchart of an embodiment of a method for processing network node configuration information provided by an embodiment of the present invention, as shown in Fig. 1 , including the following steps:

Step 101: Store corresponding resource operation information when resource release or resource occupation occurs, and the resource operation information is used to identify that the 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 sends a resource request message to the target node to obtain a resource of a channel and a time slot, and the target node After receiving the above-mentioned resource request message, resources are allocated, and a broadcast message including resource occupation information is sent to the source node and adjacent nodes to notify that the above-mentioned allocated resources have been occupied. During this process, both the source node and the target node store and occupy In addition, after the data transmission is over, the source node sends a message requesting to release the occupied resource to the target node, and the target node releases the corresponding resource, and sends a message including resource release information to the source node and other adjacent nodes Broadcast a message to notify that the above-mentioned allocated resources have been released, and both the source node and the target node store the resource release information corresponding to the released resources;

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

Through the above-mentioned technical solution of the present invention, the technical problem caused by the unreliability of broadcast messages sent to adjacent nodes when the source node and the target node occupy or release resources can be effectively solved. When the information stored in its adjacent nodes is inconsistent, it can be further verified and adjusted to effectively improve network performance and achieve normal network operation.

On the basis of the above embodiments, if the first adjacent node modifies the value of the bit corresponding to the above-mentioned occupied resources in the configuration bitmap configured by itself after receiving the resource occupation notification message; or the first adjacent node After receiving the resource release notification message, query whether the above resource is occupied by its own first adjacent node or whether the above resource is occupied by a second adjacent node adjacent to the first adjacent node.

The following is a specific embodiment of the present invention, as shown in Figure 6, when the network node A (source node) applies to the network node B (target node) to release the previously applied EGTS resource, the network node A will send the EGTS to the node B Request command frame, the command frame contains part of the ABT information that needs to be released. After the network node B receives the release application from the network node A, that is, the EGTS Request command frame, it will send its own ABT information and part of the ABT information carried in the command frame The information is compared, the corresponding time slot and channel resources are released, and a response broadcast EGTS Reply command frame is sent to declare to the adjacent node that the resource has been released. Nodes within a hop range around network node B, including network node A, will receive the broadcast information, and nodes around network node B, such as network C nodes, will also know that node B has released a certain amount of time and channel resources, and will broadcast information based on the broadcast information The ABT table released in , updates its own ABT, and marks 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 will record the release operation inside the device, that is, the resource operation information in the above-mentioned embodiments of the present invention, and the record will be kept until the released resource is reoccupied by other network nodes or itself. After network node A receives the response broadcast message sent by network node B, it will also update its own ABT accordingly, and broadcast an EGTS Notify command frame to declare to the adjacent nodes of network node A that the resource has been released. At the same time, network node A will record the operation, and the record will be kept until the released resource is reoccupied by other network nodes or itself. In this way, the release operation is recorded in both the receiving and sending nodes, providing necessary information for subsequent ABT resource comparison.

When network node A (or network node B, network node A is taken here as an example) receives information related to ABT from a neighboring node, such as network node D, such as listening to EGTS Reply or EGTS Notify of network node D, etc. The broadcast information 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 network node A itself is marked as occupied in the ABT of network node D, network node A understands that network node D has not received its own broadcast message to release the resource, so it "good faith" Unicast a data packet to network node D, that is, the resource release notification message mentioned in the above embodiment, to remind network node D that the resource has been released by network node A. After receiving the prompt information, the network node D will check to determine whether the resource is being occupied by itself or an adjacent node and has not been released. It can be understood that the adjacent nodes of network node D are not completely consistent with the adjacent nodes of network node A. If the resource is occupied by network node D itself, it will reply to network node A that the resource is being used by network node D, and network node A as an adjacent node should mark the area resource as occupied after receiving the information ; If it is not occupied by network node D itself but is occupied by other adjacent nodes of network node D, it will also return a response message to network node A and explain that the resource is reasonably occupied. After receiving the above response message, network node A will not It will modify its own ABT, unless the adjacent nodes of network node A and network node B occupy the above-mentioned resources; if there is no record indicating that the above-mentioned resources are in a reasonable occupation state, it means that the resource is due to network node D not listening to the network It is left over from the broadcast message sent by node A, so the bit corresponding to the resource in the ABT of network node D will be released and cleared to indicate that the resource is in an idle state, and at the same time send to network node A that the resource in the ABT A response message for releasing and clearing the bits corresponding to the above resources.

When network node A unicasts a data packet to network node D, that is, the resource release notification message mentioned in the above-mentioned embodiment, the frame structure of the data packet may be as shown in FIG. 7, which may include a frame header of 7 subsections, 1-byte command identifier and variable (i.e. load), where the frame header can include the address information of network node A, the command identifier is used to indicate that the data packet is a unicast query frame, and the variable includes the address information of network node A The record is released, and the occupied resource information is recorded in the ABT information contained 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, a resource is occupied or idle can be indicated by one bit, that is, 1 indicates that the resource is occupied, and 0 indicates that the resource is idle.

After network node D receives the above data packets, it will query the relevant ABT resources occupied by itself. If the relevant ABT resources are occupied by network node D itself, it will feed back the information to network node A and notify the network The resource of node A is being used by network node D, and network node A is also required to mark that the resource has been used on the ABT table; if the relevant ABT resource is occupied by the adjacent node of network node D, then network node D feeds back to Network node A sends a response message, indicating that the resource is used by its own adjacent nodes, and network node A does not need to do any processing; if the above resources are neither occupied by network node D nor by other adjacent nodes of network node D If the resource is occupied, it can be determined that the resource is a leftover resource that has not been released, and then the network node D performs a release operation, and modifies the information corresponding to the above resource in the configuration bitmap of the configuration, that is, the value of the corresponding bit is set to zero, so that in The ABT table indicates that the resource is free, and at the same time sends a response message to network node A including the value of the bit corresponding to the resource in the configuration bitmap in which network node D has modified the configuration.

Through the above query and comparison process, the network node can effectively clean up the ABT resources of adjacent nodes through the operation records in its own ABT, and release more available channel and time slot resources.

Storing resource operations can also be used in the resource application process of EGTS. Also as shown in Figure 6, network node A applies for EGTS resources from network node B, network node B sends the EGTSReply broadcast frame, and node A will continue to send the EGTS Notify broadcast frame. Afterwards, Node A and Node B will record the resource application operation and related ABT resources. In the subsequent communication process, network node A or network node B monitors the ABT resources in the EGTS-related broadcast frames of neighboring nodes, and compares them with the resource operation records stored by itself. Once it finds that the EGTS resources it has applied for are not in the surrounding The ABT identification issued by other adjacent nodes will send a message to the network node that issued the EGTS related broadcast frame, informing the network node that the relevant resource has been occupied by itself, as an adjacent node, it needs to identify the relevant bit as Occupancy sign. After receiving the above-mentioned message, the network node that issued the EGTS-related broadcast frame will identify the corresponding resource, indicating that the corresponding resource has been occupied, for example, in the configuration bitmap stored by the network node. 1.
