Group Key Management Scheme Design for Heterogeneous Wireless Sensor Network
Tao Ma · Jisuanji gongcheng · 2011
To solve the great energy cost and poor efficiency of group key updating in Heterogeneous Wireless Sensor Network(HWSN),this paper proposes a group key management scheme based on topological information for HWSN.The scheme takes topological information of nodes to build an αβ key management tree.In the process of generating and updating,the group key management tree must be optimized to decrease energy cost and updating delay.Simulation experiments show that the scheme is an efficient and scalable group key management scheme which is suitable for heterogeneous Wireless Sensor Network(WSN).
