中文摘要：

在这份报纸，我们为试图最大化双向继电器系统的和率的双向继电器网络建议了一种多继电器选择和力量分配计划。首先，联网一生延长，多继电器选择策略在两个隧道状态信息(CSI ) 和留下的精力(RE ) 在哪个被考虑被建议。下次，一个多继电器力量分配算法基于凸的优化(MRPA 公司) 被介绍。减少计算复杂性，它能被划分成二步：终端节点驱动分配(TNPA ) ，继电器节点驱动分配(RNPA ) 。模拟结果显示建议继电器选择策略罐头显著地与仅仅考虑 CSI 的另外的继电器选择策略相比延长网络一生，并且 MRPA 公司算法在双向继电器网络在和率上比相等的功率分配(EPA ) 有大优点。

英文摘要：

In this paper, we have proposed a multi-relay selection and power allocation scheme for two-way relay network which aims to maximize the sum-rate of two-way relay system. First, to prolong network lifetime, a multi-relay selection strategy is proposed in which both channel state information （CSI） and remaining energy （RE） are considered. Next, a multi-relay power allocation algorithm based on convex optimization （MRPA-CO） is presented. To reduce the computational complexity, it can be divided into two steps： terminal nodes power allocation （TNPA） and relay nodes power allocation （RNPA）. Simulation results indicate that the proposed relay selection strategy can significantly prolong network lifetime compared to other relay selection strategies which consider CSI only, and the MRPA-CO algorithm has great advantage over equal power allocation （EPA） on sum-rate in two-way relay network.
