WSN中引入移动节点的路由协议设计与仿真

对于节点部署不均或者节点死亡而导致的监测盲区,可通过在WSN中引入移动节点来修复。提出一种修复策略,可较为及时、准确地修复监测盲区,同时考虑节点的能量均衡问题。在LEACH-M分簇路由算法的基础上,给出了一种按节点能量分配工作量的能量均衡分簇路由算法LEACH-M-G,并运用MATLAB仿真工具进行了仿真分析。仿真结果表明,所提出的监测盲区修复策略、以及LEACH-M-G路由能有效地修复监测盲区,均衡网络能量、延长网络生命周期。

Routing Protocol Design and Simulation of Wireless Sensor Network with Introduced Mobile Node

Blind spot caused by uneven node deployment or node death, could be restored by introducing mobile node into WSN. A repair strategy is proposed to restore the monitoring blind spots timely and accurately, and this strategy also gives consideration of node energy balance. Based on the LEACH-M clustering routing algorithm, an energy balance clustering routing algorithm LEACH-M-G is proposed which could distribute workload in accordance with node energy.Simulation with MATLAB indicates that the proposed repair strategy for monitoring blind spot and LEACH-M-G route could effectively repair monitoring blind spots, balance the network energy and prolong the network lifecycle.
