Abstract: Next generation wireless networks are expected to include heterogeneous wireless networks to offer a diverse range of multimedia services to mobile users. Due to the heterogeneity and the diversity of access networks, various user applications with different Quality of Service (QoS) requirements pose new challenges on multi-interface Mobile Terminal (MT) in designing optimal network selection algorithm for guaranteeing seamless QoS support to the users. Thus, vertical hand off (VHO) is necessary to provide uninterrupted services to mobile users anywhere and anytime in 4G Networks. In this paper, a Modified Weight Function based Network Selection Algorithm (MWF-NSA) that considers user preference and application profile is proposed. It considers the characteristics of both network conditions and connection performance in deciding the weight functions of the network parameters in order to reflect the importance of each metric in network selection algorithm. Our Matlab simulation results show that the proposed algorithm selects the best suitable network among UMTS, WiMAX and WLAN networks, while achieving balance between user preference and QoS requirements of running applications.
