The research on a Multipath Forwarding Strategy in Wireless Sensor Networks

Wireless communication signals are unstable, WSN network topology changes frequently, network dynamics are strong, and single path forwarding is difficult to provide high quality of service. A vector address-based end-to-end multi-path forwarding mechanism and path recovery algorithm are proposed. Although a single path cannot continuously guarantee network connection, multiple paths together can provide network connection with high reliability. In this method, the caller applies for and stores multiple relatively independent communication paths, and ranks them for use according to the path cost. The experimental results show that the performance of the above method is significantly improved.
