Embodiment

[0158] refer to Figure 6 , for a routing method and the original method of monitoring path node energy and queue length according to the present invention to establish a schematic diagram of a path

[0159] refer to Figure 6 , where the initial energy of each node is set to 30J, and the queue capacity of each node is Q full . The original method is AOMDV, and we call a routing method for monitoring path node energy and queue length in the present invention DEQDAOMDV.

[0160] Since AOMDV establishes the shortest path as the main path based on the hop count information as the only routing criterion, from Figure 6 It can be seen from the figure that S-A-B-C-D is the shortest path from the source node to the destination node, with 4 hops and 5 hops for other paths, so the main path established by AOMDV is S-A-B-C-D.

[0161] When DEQDAOMDV establishes a route, it first expands the relevant routing control group and path state information, and then makes a routing request. ...

Abstract

The invention discloses a routing method for monitoring path node energy and queue length, which overcomes the problems in the prior art that the established path is not an optimal path and uneven load easily leads to network failure. The method includes: 1. Related routing control grouping Expansion of: 1) extended routing request grouping RREQ, adding request energy flag bits etc. on the basis of RREQ grouping of AOMDV agreement; 3) Expand the format of the Hello packet, add the minimum suitability path destination address, the minimum suitability path energy flag, etc. on the basis of the Hello packet of the AOMDV protocol; 2. Expansion of the path state information; 3. Routing Request process: 4. Routing response process; 5. Nodes use Hello packets to dynamically monitor network path information.

Description

technical field [0001] The invention relates to a method belonging to the field of wireless sensor network routing protocols, more precisely, the invention relates to a routing method for monitoring path node energy and queue length. Background technique [0002] A wireless sensor network (Wireless Sensor Network, WSN) is composed of a large number of sensor nodes distributed in the target monitoring area. The sensor nodes periodically sense the useful information of the surrounding environment and perform simple processing. The sensor nodes communicate, and the information collected by the source miniature sensor nodes is transmitted to the base station for final processing through single-hop or multi-hop in the form of wireless transmission. WSN has the advantages of large-scale, self-organization, data-centric, collaborative work, etc., and has broad application prospects. However, WSN also has its own shortcomings. Due to the limited energy and network bandwidth resourc...
