一种面向电池供电中继节点的中继选择方法
A Relay Selection Method for Battery-dependent Relay Nodes
摘要
Abstract
Due to the fast power consumption and even the reduction of network lifetime caused by the frequent data forwarding for the battery-dependent relay nodes with higher channel qualities in collaborative communication network,a relay selection method is proposed considering the battery energy consumption,remaining battery and the Channel State Information(CSI) simultaneously.The Signal to Noise Ratio(SNR) is weighted according to the ratio of battery energy consumption and remaining battery,then the source node or the relay node of the relay link with maximum weighted SNR is chosen to transmit the data.The average forwarding channel capacity and outage probability of the system are derived.On this basis,simulation results show that the proposed method can reduce the battery energy consumption of the relay nodes and extend the life cycle of collaborative communication network while guaranteeing the forward channel capacity and outage performance.关键词
