摘要：
Considering frequent mobility of wireless sensor networks, an efficient random key pre-distribution scheme was proposed. In the scheme, the network was divided in square 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, obtains up to 60% reduction in the number keys.
