摘要
本文针对无线传感器网络能量、计算能力、存储空间以及带宽等局限性问题,提出了一种新的无线传感器网络密钥预分配方案。通过将目标区域分为若干个子区域,然后对各个子区域分别部署密钥。分析表明,该方案具有良好的连通性和高效性。
Considering limitation of power, computation and storage resources of wireless sensor networks, a key pre-distribution scheme for wireless sensor networks is presented. The target area is divided into a number of sub-regions, and then keys of each sub-region are deployed. Theoretic studies show that the scheme has good connectivity and high efficiency.
