Problems solved by technology

[0006] The communication quality of the Ad-hoc network is greatly affected by the wireless channel conditions. The sudden change of the channel quality will cause the original effective link to fail, and the data transmission will be interrupted, especially in the outdoor or wild scene, where the interference factors in the environment are more complex and Unpredictable, leading to poor channel parameter stability
In addition, the nodes of the Ad-hoc network are mobile, so the topology of the network may change greatly in a short period of time.
These problems have brought great challenges to the reliable communication of Ad-hoc network

Abstract

The invention discloses an improved wireless ad hoc network multi-link routing method. Update module, timeliness check module, link monitoring module, link switching module and routing information broadcasting module; 2) Initialize the local routing table, enter the current node information into the local routing table and broadcast, and check whether the route is outdated; 3) Extract the source node and the sink node from the routing information sent by the neighbor node, find out the N shortest distance routes from the source node to the sink node and sort them according to the distance, select an optimal route as the main route, and the rest N- 1 route is used as a backup route; then the routing table information is updated and the routing information is broadcast; 4) When the number of lost packets of the node reaches the preset upper limit, a route is found from the backup route to perform link switching.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to an improved Ad-hoc network multi-link routing method based on Bellman-Ford algorithm. Background technique [0002] A wireless ad hoc network (Ad-hoc network) has the characteristics of no center and self-organization, and nodes in the network dynamically establish connections with other nodes. Therefore, the focus of realizing data transmission in Ad-hoc networks is how to find an available and reliable transmission link between the source node and the sink node. For this routing problem, the existing protocols and algorithms are roughly as follows: Several categories: [0003] Traditional routing protocol: AODV protocol is a typical protocol in Ad-Hoc network. The main feature of this protocol is to generate routes on demand. The structure of the protocol is simple and easy to implement. However, when the topology of the nodes in the network changes or ...
