Seamless mobility management of the mesh clients (MCs) in wireless mesh network (WMN) has drawn a lot of attention from the research community. A number of mobility management schemes such as mesh network with mobility management (MEMO), mesh mobility management (M(3)), and wireless mesh mobility management (WMM) have been proposed. The common problem with these schemes is that they impose uniform criteria on all the MCs for sending route update message irrespective of their distinct characteristics. This paper proposes a session-to-mobility ratio (SMR) based dynamic mobility management scheme for handling both internet and intranet traffic. To reduce the total communication cost, this scheme considers each MC's session and mobility characteristics by dynamically determining optimal threshold SMR value for each MC. A numerical analysis of the proposed scheme has been carried out. Comparison with other schemes shows that the proposed scheme outperforms MEMO, M(3), and WMM with respect to total cost.
无线网状网络(WMN)中网状客户端(MC)的无缝移动性管理已引起研究界的广泛关注。已经提出了许多移动性管理方案,如具有移动性管理的网状网络(MEMO)、网状移动性管理(M(3))和无线网状移动性管理(WMM)。这些方案的共同问题是,无论MC的不同特性如何,它们都对所有MC施加统一的标准来发送路由更新消息。本文提出了一种基于会话与移动性比率(SMR)的动态移动性管理方案,用于处理互联网和内联网流量。为了降低总通信成本,该方案通过动态确定每个MC的最佳阈值SMR值来考虑每个MC的会话和移动性特征。已对该方案进行了数值分析。与其他方案的比较表明,该方案在总成本方面优于MEMO、M(3)和WMM。
