基于故障节点无线传感网络的数据汇聚算法
Data gathering algorithm for fault nodes in wireless sensor network
摘要
Abstract
The node of wireless sensor network(WSN)is liable to fault because the influence of the nuclear radiation envi-ronment and limitation of node energy,so how to realize effective data aggregation based on fault nodes in WSN environment has become the research hotspot. The influence of nuclear radiation on RF communication ability of nodes is studied. The data gathering protocol for radiation affected(DGP-RA)algorithm for WSNs data aggregation under nuclear radiation restraint is pro-posed,in which the node has dual modes of radio frequency communication and acoustic communication. The DGP-RA algo-rithm based on reward and punishment mechanism,Dempster Shafer theory(DST)and hypothesis testing theory are used to identify the fault node which can′t communicate because the influence of nuclear radiation,and switch the communication modes adaptively to resist the radiation influence. The simulation results show that the DGP-RA algorithm can improve the data transmission efficiency effectively and reduce the energy consumption.关键词
