Non-uniform deployment scheme of energy consumption equilibrium in linear wireless sensor networks

针对线性无线传感器网络中存在能量空洞的问题,给出一种线性无线传感器网络能耗均衡的非均匀网络部署方案。该方案证明了除距离Sink节点最远的子监测区域之外,剩余子监测区域从远到近使其传感器节点数量呈等比递增时可实现网络能耗均衡,同时需随机部署足够数量的中继传感器节点用于转发数据。经实测数据仿真表明,所提方案能有效地解决能量空洞问题,使得线性无线传感器网络可以实现均衡能耗的目的,且能够大大延长网络的寿命,对于提高实际线性无线传感网络的性能具有重要意义。

Aiming at the problem of energy hole in linear wireless sensor networks,a non-uniform deployment scheme of energy consumption equilibrium in linear wireless sensor network is proposed.The scheme proves that in addition to the sub-monitoring area furthest from the Sink node,the remaining sub-monitoring area can achieve network energy consumption balance when the number of sensor nodes in it increases equally from far to near,and a sufficient number of relay sensor nodes need to be randomly deployed to forward data.The simulation results show that the proposed scheme can effectively solve the problem of energy hole,make the linear wireless sensor network can achieve the goal of balanced energy consumption,and greatly extend the life of the network,which is of great significance for improving the performance of the actual linear wireless sensor network.
