基于虚拟引力的WSNs路由协议设计与实现

数据采集是无线传感器网络(WSNs)主要功能之一,大规模的传感器网络采集并回收数据时容易出现节点负载不均衡,导致负载重的节点过早死亡.为了延长传感器网络的生存时间,本文提出了一种基于虚拟力的分簇路由协议(CRPVG),选取合适的节点出任簇首;根据簇首与普通节点的虚拟引力大小进行分簇;通过簇首之间多条传输将采集的数据包发送至基站节点.实验结果表明:提出的分簇路由协议在能耗均衡方面起到了较好的作用,延长了网络的生存时间.

Design and realization of WSNs routing protocol based on virtual gravity

One of the main uses of wireless sensor networks (WSNs) is data acquisition.Large-scale sensor networks are prone to load imbalance in nodes when collecting and reclaiming data,which leads to premature death of heavy load nodes.In order to prolong the survival time of the sensor network,propose a clustering routing protocol based on virtual gravity(CRPVG).The protocol chooses appropriate nodes as cluster head,and according to size of the virtual gravity of cluster head and normal nodes for clustering,send collected data packets to the base station nodes through multiple transmission between cluster head nodes.The experimental results show that the proposed clustering routing protocol can play good role in energy balance and prolong the survival time of the network.
