Efficient Mobility Management in Different Wireless Network for Continuous Flow of Information

Mr. P.Thirunavukkarasu, Ms. P.Irene Beril Yazhini

Next generation wireless communication systems are expected to relay on integrated networks consisting of multiple wireless technologies. Heterogeneous wireless networks, for instance WiMAX and Wi-Fi can combine their respective advantages, offering a high Quality of Service (QoS) and Always Best Connected with mobile users. Mobility management was deployed in Application layer using SIP protocol to provide quality of Real time services to the end user. The vertical handoff decision is crucial in heterogeneous networks. In this paper, we propose Enhanced vertical handoff decision based on BANS in WiMAX and Wi-Fi heterogeneous wireless networks. The algorithm consider the factors of Received Signal Strength (RSS), Bandwidth (BW), mobile node velocity (V) and User Preference (P), to evaluate Network Selection Function of the available networks and select best one which support on going real time application (i.e., video streaming).To decrease Call Blocking Probability we propose Adaptive Bandwidth Allocation Algorithm(ABAA). We propose TBHO method to make an early handover to avoid Ping-Pong effect which causes the unwanted packet loss.
