摘要
在无线传感器网络中,通过为进攻的入侵者寻找入侵轨迹来实现栅栏覆盖控制是比较有效的方法。在兼顾安全性能和时效性能,并且无需全网拓扑信息的支持的前提下,提出一种新型的入侵轨迹算法:SS(Security&Speed)算法。该算法形成的轨迹能动态地反映入侵者对上述两种性能的需求差异。和传统的Worst-coverage方法相比,该模型对网络中节点密度的变化有更低的敏感性,计算复杂度降低的同时仍能较好地接近理想结果。
Searching the attacking locomotion trajectory is a valid method for the barrier-coverage control in wireless sensor networks. Without any information of topology, an algorithm called as SS（Security ＆ Speed）algorithm, is presented to build attacking locomotion trajectory. This trajectory can image the different of above two demands. Compared with the traditional worst-coverage algorithm, the proposed SS algorithm can match the results of the optimal more closely and has smaller complexity than the optimal approach.
