Abstract: This book chapter presents a tutorial on vertical handoff methods in the evolving 4G wireless communication networks. Integration architectures for various wireless access networks are described. Then handoff classification, desirable handoff features, the handoff process, and multimode mobile terminals are discussed. A section is devoted to some recently proposed vertical handoff techniques. We propose a vertical handoff decision algorithm that determines whether a vertical handoff should be initiated and dynamically selects the optimum network connection from the available access network technologies to continue with an existing service or begin another service.
Keywords: Heterogeneous Wireless Access Networks, Vertical Handoffs in 4G Wireless Networks, Recently Proposed Vertical Handoff Techniques and Performance Evaluation of Network Selection.
