Abstract: The combination of the wireless ad-hoc network and the future cellular mobile communication system attracts more and more study and attention from the academic and industrial circles. This thesis discusses in detail about the necessity of introducing ad-hoc mode, the developing trend of the multi-hop cellular network technology at home and abroad and the system architecture in the situation of a single cellular. It stresses on the introduction of the agent-get problems and distributed agent-get algorithm based on hop count, and conducts simulation analyses of the effects of each parameter on the agent-get probability in the situation of single cellular. The simulation result indicates that enlarging the radius of the cellular and the nodes’ transmission radius can effectively increase the agent-get probability, and increasing the hop-limit can effectively improve the agent-get probability only when the hop-limit is rather small.

Key words: Communication Mode, Agent-Get, Multi-hop Cellular Network

摘要： 无线自组织网与未来蜂窝移动通信系统的结合吸引了学术界和产业界越来越多的研究与关注。本文就引入自组织方式的必要性，多跳蜂窝网络技术的国内外发展趋势以及单小区环境下的系统模型等做了详细的论述，重点介绍了代理选取问题及基于跳数的分布式代理选取算法，对基于该算法的单小区环境中各参数对代理选取概率的影响进行了仿真分析。仿真结果表明，提高小区的覆盖半径和节点的通信半径是增加代理选取概率的有效方法，而增大搜索的跳数范围却只能在跳数范围较小时有效的提高代理选取概率。
