The integration of the widely spread 3rd Generation (3G) Universal Mobile Telecommunication System (UMTS) with the Wireless Local Area Networks (WLANs) has recently attracted considerable attention. However, addressing seamless and transparent handoff during mobility between these networks is still the biggest challenge to overcome. This paper evaluates the(More)
—Mobile IP is one of the popular mobility solution and a viable candidate for the Beyond 3rd Generation (B3G) networks such as the integrated 3rd Generation Universal Mobile Telecommunications System (UMTS) and the Wireless Local Area Networks (WLANs). Mobile IP has many configuration and enhancements that are proposed by IETF such as the Care-of-Address(More)
As wireless Internet applications are proliferating and becoming the main driver for the exploding growth of wireless access technologies, integrating third generation (3G) systems with Wi-Fi networks allows combining the strengths of these two technologies. In this paper, we present a novel design for a dual-mode user equipment (UE) model that supports(More)
Transmission Protocol (mSCTP) that may be used to provide session continuity in the integrated network. The vertical handoff delay figure is analyzed using simulations for different WLAN speeds and its major components due to the involved signaling procedures are quantified. The results are derived from our developed OPNET based simulation model that(More)
