摘　　要：无线自组网是一种分布式结构的网络,其中每个节点都与邻居节点直接操作,从而协同完成寻路、拓扑控制等全局任务,因此邻居管理对于无线自组网有着重要的意义.本文针对单接口多信道自组网,提出多信道网络中的邻居管理的问题,并设计一种基于多重公告的邻居管理机制MANM(Multiple-Announcement Neighbor Management).MANM通过周期产生的多重公告,向各个信道中的邻居节点广播其对应信道信息.分析与模拟实验表明,MANM可以有效管理各个信道的邻居节点信息,为优化多信道网络性能提供基础支持.In a distributed wireless ad hoc network each node performs localized operations on its own neighborhood in order to complete a distributed task such as routing,topology control and etc. Thus the performance of such network greatly depends on neighbor management. This paper presents the neighbor management problem in single-radio multi-channel ad hoc networks, and propose a Multiple-Announcement Neighbor Management （MANM） method. With MANM,each node generates multiple announcements including its neighbor and channel information ,and periodically broadcasts each announcement in corresponding channel such that all the neighbors on all channels can collect the neighborhood information. Analysis and simulation results indicate that MANM is a promising method for discovering multi-channel neighbors as well as an extensible platform which provides basic support for various services in multi-channel ad hoc networks.
