基于主动路由的无线mesh网络区域移动管理方法

摘要

This paper proposes an active routing based infra-domain mobility management (ARMM) for wireless mesh networks. ARMM combines the location update procedure of mobile stations with the active routing procedure of mesh routes, which makes the mesh routers perform location management, on behalf of the mobile stations that are attached to them. Thus, the mesh routes can locate the mobile stations attached to them. This paper proposes the two-layer routing model, routing algorithm and location update mechanism. The performance analysis shows that, compared to the existing solution, ARMM has shorter handover delay, and a smaller location update and delivery cost.%提出了一种无线mesh网络中基于主动路由的区域移动管理(active routing based intra-domain mobility management,简称ARMM)方法,将移动终端(mobile station,简称MS)的位置更新和mesh路由器(mesh route,简称MR)之间的动态路由相结合,让MR代替附着在它上面的MS进行位置管理,从而实现MR对MS的定位.给出了ARMM方法中的二层路由模型、路由算法及位置更新机制.性能分析结果表明,相对于现有的区域移动管理方法,ARMM方法具有较小的切换延时、位置更新开销和数据传输开销.
