摘要
针对无线传感器网络(Wireless Sensor Network,WSN)中邻近汇聚节点(sink)的传感节点负荷和能耗过载问题,基于整体网络能耗平衡目标,提出一种不等环的次优分层网络路由。在均匀分布的传感节点环境中,以sink为中心,按照拓扑距离进行分环多跳路由,理论推导了不等环半径,并考虑单跳能耗。实验分析仿真结果表明,该路由分层模型延长了网络生存周期,提高了节点利用效率,且达到网络内大部分节点能耗均衡的目标。
Aiming at the problem of the load and energy overload in the nodes around the sink,this paper proposed a suboptimal network routing model with inequality rings based on the theory of balance energy consumption of the whole network.This model makes use of uniform node distribution around the sink,routing between rings according to the topology radius,which is deduced combined with energy consumption.Performance analysis and simulation results show that the proposed model extends the network lifetime,improves the utilization efficiency of nodes,and reaches the goal of energy balance of most nodes in the network.
