QoS Based Mobility Management for Wireless Mesh Networks

Abstract

Radio resource is one among the prime resources in wireless networks which is expected to use in an efficient way especially when the mobile user is on move. This paper proposes QoS Based Mobility Management (QBMM) for Wireless Mesh Networks. It is aimed to decrease the overall network traffic due to the mobility of the users within the network while ensuring the QoS. To accomplish this, pointer forwarding mechanism with Expected Transmission Count as routing metric is used. The proposed algorithm is analyzed for signaling cost, data delivery cost and throughput for both Internet sessions and Intranet sessions. Significant throughput improvement is achieved while maintaining the overall communication cost at low.
