Key pre-distribution is the most important safety problem in wireless sensor network.In order to ensure the wireless sensor network sensor nodes security,messages must be encrypted in transfer process.Because wireless sensor nodes have resource constraints,traditional key distribution method is unsuitable for wireless sensor networks.In order to improve the security of network communication,an improved key pre-distribution method is proposed.This algorithm uses nodes deployment and location information to increase network connectivity and reduce sensor node required storage space.Simulation experiments show that the proposed method has improved network ability against the attack,and it is more suitable for wireless sensor network security and energy consumption demand.
