Research on wireless sensor network security management.Key management is a core problem in wireless sensor network security management.Because of wireless sensor network node storage capacity,computing power and node energy are limited,and traditional network key management schemes are unsuitable for to wireless sensor networks.Traditional three-key management schemes has the defects of complex structure and poor network connectivity,so the paper puts forward an improved three-key management scheme.Firstly,wireless sensor network topology structure is built based on LEACH,a single cluster head node is structured to simplify the structure of network.Then the security routing is adjusted adaptively to increase network connectivity.Simulation experiment is carried out on OMNet++ platform.The experimental results show that,compared with other wireless sensor network key management schemes,the proposed network scheme has improved the power of resisting attack,and network connectivity probability is increased.It is very suitable for higher safety for wireless sensor network.
