摘　　要：无线自组织网与未来蜂窝移动通信系统的融合代表未来无线网络的发展趋势。引入自组织方式的必要性划分为形成局域子网、虚拟小区分裂和虚拟小区扩展三个方面。对现有的国内外研究机构提出的系统模型进行了类型划分,针对代理选取问题提出了基于跳数的分布式代理选取算法,并对基于该算法的单小区环境中各个系统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地提高代理选取概率。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.
