Abstract

The wireless communication signal is unstable, the WSN network topology changes frequently, and the network is dynamic. When forwarding, select the optimal vector address of a path and forward according to the vector forwarding mechanism. If the forwarding fails, start the path recovery algorithm and select the alternate path Perform data forwarding. The switching speed of the backup path is independent of the routing speed of the control plane, so end-to-end fast path switching can be realized, so that under the condition of lower route convergence speed, the purpose of "low latency and high reliability" communication can still be achieved. In the experiment, ten paths with the best paths are selected as alternative paths, and the path recovery under different hop counts are simulated respectively. The experimental results show that the performance of the above method is significantly improved.
