Handover Decision Based on User Preferences in Heterogeneous Wireless Networks
A handover decision is a significant problem, in next generation of wireless networks (4G). This is exacerbated when the handoff decision is driven by user preferences (mainly transmission cost and wireless interface power consumption), wireless environment constraints (access network availability and properties and client communication capabilities). In this paper, the authors present a handoff decision based on user preferences which consider not only the traditional handover decision factor (RSS) but also user preferences, user profiles and other requirements. They introduce APBSW (Access Point Best Satisfied Weights) for selecting access network; their proposed methods, UPHO (User Preference HandOff) use a fuzzy logic-based inference system to process all appropriate context information, which satisfy the best user preferences.
