Abstract 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.
