分层多跳无线网中结合负载均衡的切换管理

Handoff Management Based on Route Optimization in Hierarchically Multi-hop Wireless Networks

该文主要研究分层多跳无线网络中的切换管理,提出一种新的用户切换管理算法和移动基站路由切换策略。在网络动态变化时,用户切换管理算法可以减少用户的切换次数,使用户负载分布均匀。移动基站路由切换策略则尽可能地从基站本地找出替代路由,可以在较小的开销下达到快速和无缝切换的目的。

This paper studies on handoff management in hierarchically multi-hop wireless networks and proposes a novel user handoff algorithm and mobile base station route handoff strategy. The user handoff algorithm can reduce the number of handoff and balance the load among mobile base stations in dynamic topology. Meanwhile the mobile base station handoff algorithm always tries to find an alternate route from base station locally, which can achieve fast handoff and seamless handoffwith little overhead.
