Design and analysis of an adaptive mobility management scheme for handling internet traffic in wireless mesh network

Wireless Mesh Network (WMN) has emerged as an important technology in recent years. A major problem with WMN is provisioning of seamless and high speed internet connectivity to the mobile Mesh Clients (MC). For solving this problem many mobility management protocols for example imesh, MEsh networks with MObility management and Mesh Mobility Management have been proposed. The disadvantage of the schemes is higher cost for mobility management. This paper proposes a session-to-mobility ratio (SMR) based mobility management scheme. The scheme enables the MC to send location update message to the gateway, uses forward chain, tunneling and a threshold SMR value for reducing the cost of mobility management. The effect of selection of the threshold SMR on cost per handoff, cost per packet delivery and total communication cost per time unit have been investigated in the paper.
