基于H_∞滤波能量预测中继选择协作传输技术

This paper researched a mobile cooperative data transmission technology based on energy prediction for distributed wireless sensor network.Wireless sensor network,collaborative data transmission technology was difficult to effectively solve the wireless network dynamic topology,limited bandwidth and energy problem,which was based on H∞ filter adjacent node residual energy prediction for distributed relay selection scheme based on data collaboration transmission technology.The technology made full use of the broadcast characteristic of wireless channel,first established according to the H∞ filter for prediction of residual energy of nodes,and then chose the biggest as cooperative node according to the remaining energy value,according to the wireless channel quality,it adaptively adjustment between AF and DF mechanism.Mathematical analysis shows that the H∞ filter can accurately predict the residual energy of nodes,at the same time the cooperative transmission technology can significantly improve the wireless sensor network resource utilization and throughput rate of the system,prolong the network lifetime efficiently.
