摘要: 能量空洞现象的出现缩短无线传感器网络的寿命,制约无线传感器网络在线性监控区域内的应用。为此,提出一种节点非均匀布置方案。在节点的布置中对于不同的区域采用限制节点数目的方式,使节点数目从外到内按等比数列递增,并随机布置一定数目的中继节点来转发数据。仿真实验结果表明,该方案可实现次优网络能耗均衡,延长无线传感器网络系统的生命周期。

Abstract: For the phenomenon of the energy hole greatly reduces the lifetime of Wireless Sensor Network(WSN), constrains the application of WSN in the linear region of monitoring. This paper proposes a program of node non-uniform arrangement scheme. The arrangement of the nodes in the different areas uses the limit for the node number way, makes point number from outside to inside increase according to the sequence, and arranges randomly a certain number of relay node to forward packets. Simulation experimental results show that this scheme can realize subprime network energy consumption equilibrium, prolong WSN system life cycle.

Key words: linear Wireless Sensor Network(WSN), node non-uniform arrangement, subprime network equilibrium, energy hole, relay node, work node
