【摘要】：针对无线传感器网络(WSN)中存在的"能量空洞"问题,设计一种适用于无线传感器网络的多sink环境下能量空洞避免方案MS-EHA(multiple sink-energy hole avoiding)。采取轮的思想,按周期在每轮的开始阶段,sink的位置会重新定位;在路由选择阶段,将综合考虑节点间的最小跳数以及路径上节点的能量消耗速率,增加路由修复机制,减少数据传输的延迟,提高网络通信的灵活性与效率。仿真与分析结果表明,与传统的DSR(动态源路由协议)相比较,该方案有效降低了网络能量消耗与节点间的路由跳数,减少了数据包的丢失数目,缓解了传感器网络的能量空洞现象,降低了网络延迟,较大程度提高了数据包的传输效率。
[Abstract]:In order to solve the problem of "energy hole" in wireless sensor network (WSN), an energy void avoidance scheme, MS-EHA(multiple sink-energy hole avoidance scheme, is designed for wireless sensor networks in multiple sink environments. Adopting the idea of wheel, the sink position will be relocated at the beginning of each round according to the cycle, and in the route selection stage, the minimum number of hops between nodes and the energy consumption rate of the nodes on the path will be considered synthetically, so as to increase the routing repair mechanism. Reduce the delay of data transmission and improve the flexibility and efficiency of network communication. The simulation and analysis results show that compared with the traditional DSRs, the proposed scheme can effectively reduce the network energy consumption and the number of routing hops between nodes, and reduce the number of packets lost. The energy hole phenomenon of sensor network is alleviated, the network delay is reduced, and the transmission efficiency of data packet is greatly improved.
