Multiple-Path Redundancy Secret Anonymous Routing Protocol for Wireless Sensor Networks

For traditional anonymous routing protocols for wireless sensor networks (WSNs), the routing path is a single path, and the invalidation of any one routing node in the routing path will result in the failure of the whole routing path, this is extremely difficult in practice to guarantee the reliability of message delivery. In this paper, a secure anonymous routing protocol for wireless sensor network is proposed. The protocol can build the routing path with multiple-path redundancy and work well in hard conditions, and the protocol not only has all properties of anonymous routing, but also has the backward and forward security. Through the analysis and proof, the protocol improves distinctly in reliability and prolongs the network lifetime, and is more suitable for hard conditions of the wireless sensor networks.
