Secure neighbor relation in wireless sensor network

There are a large number of papers on security in ad hoe networks, only a few consider sensor networks. And those works on WSN mainly discuss the problem about key management. The main purposes of this work are to establish a trust on the neighbor relation in WSN and propose a solution of achieving the goal. Our solution includes a mechanism to establish a trusted relation between all neighboring nodes while avoiding untrustworthy nodes during the routing discovery process so as to resist DoS-style flooding attacks. We present our scheme, and report on its performance using an extensive set of simulation set of experiments using GloMoSim simulator.
