A tree based mobility management scheme for wireless mesh network

The importance of wireless mesh network is increasing day by day with the popularity of hand held devices. But like other wireless networks, one major problem of wireless mesh network is maintenance of network connectivity to the mobile nodes in-spite-of their random movement. For solving this problem, several mobility management schemes such as Infrastructure-mode Wireless Mesh Network (iMesh), MEsh networks with Mobility management (MEMO), Wireless mesh Mobility Management (WMM) and Mesh Mobility Management (M³) have been proposed. But the difficulty with these existing schemes is their high communication cost. In this paper a tree based proactive mobility management scheme has been proposed for handling both internet and intranet traffic. A numerical analysis of the proposed scheme has been carried out. Finally, the scheme has been compared with iMesh, MEMO and WMM.
