Key Pre-Distribution Scheme for Wireless Sensor Networks Using Regular Hexagon Deployment
Shuhua Wang · Chuangan jishu xuebao · 2013
Considering the limitations of power,computation and storage resources in wireless sensor networks,a new key management scheme for wireless sensor networks is presented.In the scheme,the network is divided into regular hexagon grid,and then the good coverage efficiency can be obtained.Nodes only need to preload a few of secret keys,and then can establish shear keys with a very high probability.Wireless sensor networks can maintain a good connectivity even though there are a lot of mobile nodes.Theoretic studies and figures of simulation show that the proposed scheme provides better performance in connectivity and security.
