摘要
本文提出了一种适用于蜂窝多跳网的路由算法。该算法充分考虑了蜂窝多跳小区以基站为中心的特点,将传统的分布式路由方式改为基站统一为各节点提供路由的集中处理方式,并定义了一套与之适应的信令。由于采用了集中的处理方式,在新方法中,基站能够通过处理和维护路由过程中所得到的信息,逐步获取小区的拓扑结构,提高路由的效率。仿真结果表明,相比于现有方法,本文提出的算法在寻路的时间上大大缩短,寻路的质量也有一定提高。
This paper proposes a method of routing in multi -hop cellular network. The method fully considers the fact that multi - hop cellular network （MCN） is based on a centric base, and changes conventional distribute routing to a centralized manner. The method also develops a set of control messages that fits it. Taking advantage of centralized processing, the base station can gradually obtain the topology of the cell through information from routing process, and makes routing more efficient o Simulation results show that compared with existed methods, this method decrease the time of route discovery significantly and also improve the routing quality.
