基于冗余节点间歇性的WSN路由协议的设计

Design of WSN Routing Protocol Based on Redundancy Node Intermittent

为解决无线传感器网络路由协议中节点能量消耗不平衡的问题,针对冗余节点过多使WSN网络生命周期较短的不足,设计一种基于冗余节点间歇性的路由协议.通过比较相邻传感器节点的监测范围覆盖率和传输数据的相似性,对发送数据被覆盖的节点进行间歇性的休眠调节,降低对感知区域监测信息采集的相互重叠.仿真结果表明:该路由协议的设计能够有效减少节点过早死亡的数量,节约网络的能量,降低节点的负载,延长网络的生命周期,并具有较高的应用推广价值.

In order to solve the problem of unbalanced node energy consumption in wireless sensor network routing protocol,a routing protocol based on redundancy node intermittent is designed to solve the problem of short life cycle of WSN due to too many redundant nodes. By comparing the monitoring coverage of the neighboring sensor nodes and the similarity of the transmitted data, the nodes with the transmitted data are intermittently sleep-adjusted to reduce the overlapping of the monitoring information in the sensing area. The simulation results show that the design of the routing protocol can effectively reduce the number of premature deaths of nodes, save the energy of network, reduce the load of nodes,prolong the life cycle of the network and have a high application value.
