摘要
无线传感器网络覆盖问题已经成为研究无线传感网络的重要问题。在目前主要研究的两种模型中,全覆盖模型能对监控区域的每一点都进行有效覆盖。栅栏覆盖仅对监控区域的水平方向布置传感器节点,可以在保证有效覆盖的同时,延长无线传感器网络的工作寿命。文中针对栅栏覆盖模型,提出新的栅栏构筑算法(district partition algorithm,DPA),它能在传感器节点部署区域构筑多条栅栏,实现多栅栏覆盖。仿真实验验证了该算法的有效性和高效性。
The coverage is an important problem in wireless sensor networks.Barrier coverage that requires much fewer sensors than full coverage,is known to be an appreciate model for detection applications.We proposed a new algorithm which is called district partition algorithm(DPA) to construct multi-barriers in detection region.It could construct more barriers than ordinary algorithm in a short time.The DPA could strengthen the stability of the barrier coverage and guarantee the reliability of the wireless sensor networks.
