| 摘 要： | 研究了无线传感器网络中基于异构节点的优化覆盖控制问题.异构无线传感器网络由两类能力不同的节点组成,包括普通节点和超级节点.对普通节点采用基于状态轮转的覆盖控制算法,对超级节点采用基于路由表的转发策略.通过两类节点的协作使得网络达到覆盖与连通的目的.模拟结果表明,在具有相同初始能量的情况下,该算法与SHHN-HS算法相比能够延长网络生命期.

| Abstract: | This paper addresses the coverage problem based on heterogeneous nodes for wireless sensor networks (WSNs).The network consists of two types of nodes which have different capabilities.For the normal-node deployment,we present a strategy based on node state transition;for the super-node deployment,we propose a strategy based on route table.By using the coordination of the two types of nodes,we provide both coverage and connectivity for the network.At last,the proposed algorithm is compared with the SHHN-HS a... |
