Deployment Scheme of Linear Wireless Sensor Networks based on Increment of Equal Number Sequence

为有效避免能量空洞现象并延长网络寿命,给出了一种基于等比数列递增的线性无线传感器网络部署方案。该方案证明了除距离Sink节点最远的子监测区域之外,剩余子监测区域从外到内使其传感器节点数量呈等比递增时可实现网络能耗均衡,同时需随机部署一定数量的中继节点来转发数据。仿真实验结果表明:所给方案可以有效避免能量空洞,实现网络能耗均衡的目的,且能大大延长网络寿命,可用于实际的线性无线传感器网络中。

In order to effectively avoid energy hole and prolong the network lifecycle,a deployment scheme of linear wireless sensor networks based on increment of equal number sequence is proposed. The proposed scheme proves that the energy consumption equilibrium could be achieved by increasing the number of sensor nodes form the outside to the inside of the sub-monitoring area apart from the sub-monitoring area farthest distance from the Sink node,and a certain number of relay nodes which are used to forward the data are needed to deploy randomly in the proposed scheme. The simulation experiment results show that the proposed scheme could effectively avoid the energy hole to achieve the purpose of the energy consumption equilibrium and could prolong the network lifecycle greatly,and could be used for the actual linear wireless sensor networks.
