摘要：

为了在提升用户吞吐量的同时降低中继节点切换概率，分析了动态场景下用户与中继节点的移动状态，提出了多目标联合优化的移动中继选择策略.算法通过分析动态场景中影响系统吞吐量与中继切换概率的因素进行中继节点选择，充分考虑了多跳蜂窝网络的移动特性和用户呼叫到达状态.仿真结果表明，所提算法在有效提升用户吞吐量的同时降低了中继切换概率.

关键词: 多跳蜂窝网络, 吞吐量, 中继切换概率, 多目标联合优化

Abstract:

The mobile relay selection problems in multi-hop cellular network are studied. The selection of mobile relay affects such performances as the throughput of the system, spectral efficiency and relay switching probability. In order to improve the throughput and reduce the relay switching probability, the mobile state of the users and the relay nodes in the dynamic scenario was analyzed, then a multi-objective joint optimization based mobile relay selection scheme was proposed. The scheme analyzes two factors which affect the system throughput and the relay switching probability in dynamic scenario. The mobile characteristic of multi-hop cellular network and the state of users' call arrival are taken into full consideration. Simulation shows that the algorithm can improve the users' throughput effectively and reduce the relay switching probability.

Key words: multi-hop cellular network, throughput, relay switching probability, multi-objective joint optimization
