Research and Improve on Secure Routing Protocols in Wireless Sensor Networks
Di Wu, Gang Hu, Gang Ni · 2008
Most routing protocols in wireless sensor networks take networks lifetime as design target, but not security. This paper researches on routing security and proposes SS-LEACH algorithm based on LEACH algorithm. The SS-LEACH algorithm makes use of nodes self-localization technology and keys pre-distribution strategy. It improves the method electing cluster-heads and forms dynamic stochastic multi-paths cluster-heads chains. The results of simulation demonstrate that the SS-LEACH algorithm not only prolongs the lifetime of wireless sensor networks effectively, but also enhances routing security strongly.
