Abstract
En 中文
We present a novel key predistribution scheme that uses deployment knowledge to divide deployment regions into overlapping clusters, each of which has its own distinct key space. Through careful construction of these clusters, network resilience is improved, without compromising connectivity or communications overhead. Experimental results show significant improvement in performance over existing schemes based on deployment knowledge.
