【摘要】 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。更多还原

【Abstract】 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.更多还原
