Abstract:One of the most important issues in wireless and mobile communication technologies is the mobility management when a mobile node moves between different access networks. Many alternative ways to realize mobility management have been proposed on different layers. In this paper we discuss the vertical handoff behavior when a mobile node moves from IEEE 802.11network to IEEE 802.16 network and vice versa using Session Initiation Protocol (SIP) in order to support real-time communication in a more efficient way in… Show more
