Simulation of Key Management Protocol in Wireless Sensor Networks

Wireless sensor networks are widely used both in the civil and military fields. Large-scale sensor nodes are usually deployed in potentially adverse or even hostile environment, so the security in these networks is very important. The design for key management protocol is one of the most important aspects and basic research field of secure wireless sensor networks. The key management in wireless sensor network meets many new challenges due to its intrinsic properties. In this paper, a key management protocol base on LEACH routing protocol is proposed, and simulation on the protocol is conducted by using NS2. Finally, the impacts on these simulation results in different network settings are presented.
