A New Kind of Cluster-based Key Management Protocol in Wireless Sensor Network
Shen Lin, Haidong Feng, Yongsheng Qiu, Hancheng Ding · 2008
Many cluster-based wireless sensor network routing protocols have been proposed to take the advantages of cluster computing. However, most of these protocols take little consideration on communication protection, which is important to ensure the network security. In this paper, a lightweight key management approach is presented. Analysis shows that this approach is an effective solution to the key management of layered cluster wireless sensor network.
