摘要：
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. © 2016, Editorial Department of Journal of Beijing University of Posts and Telecommunications.
