The next generation wireless communication system is expected to provide users with high-speed communication services through integrating multiple wireless access technologies, including cellular system, wireless local area network, worldwide interoperability for microwave access, and ad hoc network, etc. In a heterogeneous wireless network scenario, mobile nodes with multiple interfaces will be capable of choosing different access networks for service accessing and performing vertical handoff among various networks. However, the heterogeneity and incompatibility of wireless access technologies and the varieties of user service types pose difficulties and challenges to efficient vertical handoff scheme design.
