摘要:
 中继选择在协作通信中占据着重要的地位。为了获得稳定的传输和较低的复杂度，提出了基于能效的中继选择策略。首先根据最大发送功率选出可靠节点，然后以可靠节点为协作中继进行传输，再分析传输过程中的能效，得到中继选择标准，利用该标准就能得到最优的中继节点，最后分析了协作传输过程中的能耗和频谱效率。采用蒙特卡罗方法对所提算法和基于位置信息以及基于信道增益的中继选择算法进行了仿真。结果表明，相比于其他的算法，该策略能有效提高系统能量效率，增强系统传输稳定性，降低能耗，且不影响谱效率。
Abstract:
 Relay selection plays an important role in the cooperative communication. In order to obtain a stable transmission and low com-plexity,a relay selection strategy was put forward based on energy-efficient. Select reliable nodes by the maximum transmission power firstly,then use the nodes for cooperative relay transmission,getting the relay selection criteria from the analysis of energy-efficient in transmission process,having the criteria for getting the optimal relay node,finally analyze the energy consumption and spectral efficiency in transmission process. Monte Carlo method is used for the proposed algorithm and the relay selection algorithms based on location infor-mation and channel gains. Simulation results show that compared with other algorithms,the scheme can effectively improve energy-effi-ciency of the system,enhancing the transmission stability,reducing energy consumption and having no effect of spectral efficiency.
