无线传感器网络中能耗平衡的混合路由模型研究

针对无线传感器网络中能耗不均衡问题提出了一种单跳和多跳相结合的路由模型,该模型将簇内平均能量作为路由调整阈值,根据节点剩余能量对网络路由进行周期性调整,使节点路由在单跳、多跳模式间转换;通过对该路由模型能耗规律的理论分析和仿真实验,说明该模型有效地平衡了网络能耗,弥补了只采用单跳路由或多跳路由时网络能耗不平衡之不足,延长了网络生命周期.

A Mixed Route Model of Balanced Energy Consumption in Wireless Sensor Networks

This paper proposes a route model which combines single hop route with multi-hop route in order to solve the problem of unbalanced energy consumption in the wireless sensor networks. The model uses the average energy of network for the threshold of route adjusting. It changes the route of network between single hop and multi-hop periodically according to the residual energy of node. By studying the energy consumption of the model of network and simulation, it shows that this model can remedy the defect of unbalanced energy consumption in the networks using single hop or multi-hop route and prolong the lifetime of networks.
