针对现有异构无线Mesh网络缺乏对域间移动切换支持的问题,提出支持域间切换的异构无线Mesh网络层次化切换方案,区分域内切换和域间切换,降低切换时延.采用缓存策略,有效降低丢包率,支持终端的快速移动.仿真结果表明,该方案可支持速度达23 m/s的终端移动,在域间切换时,平均丢包数减少66.7%～95.5%.

There is a lack of inter-domain handoff research in the related research of mobility support to heterogeneous Wireless Mesh Network (WMN).Aiming at this problem,this paper proposes a hierarchical handoff scheme with inter-domain mobility support.It handles the intra-domain and inter-domain handoff respectively to reduce the handoff latency.It used data buffering to eliminate the packet loss and support a fast moving of the mobile node.Simulation result shows that the scheme supports a mobile node moves at 23m/s.In the inter-domain handoff,the average packet loss reduces by 66.7% to 95.5%.
