摘要 提出一种基于弧覆盖的节点调度算法来控制无线传感器网络的密度问题.利用节点感知区域所覆盖到的弧是否被邻居节点完全覆盖来判定节点的状态,通过节点之间的状态轮换与合作策略来延长网络寿命.仿真证明该算法具有良好的节能性能,而且有效延长网络的生存寿命. A node scheduling algorithm based on arc coverage to control the density of wireless sensor networks is proposed.A sensor node may keep which status ＂active＂ or ＂sleep＂ is determined by the arcs in it＇s sensor region,which can be completely covered by it＇s neighbor nodes.Through the state of rotation between nodes and cooperation strategies to extend the network lifetime.Simulation results show that the algorithm has good energy-saving performance it can prolong the network lifetime effectively.
