Secured and Seamless Handoff in Wireless Fourth Generation Systems
Faouzi Zarai, Noureddine A. Boudriga, Mohammad S. Obaidat · 2006
Satisfying quality of service (QoS) and security requirements is one of the main goals of the wireless fourth generation (4G) systems, which will integrate a multitude of different heterogeneous networks including cellular networks second generation, third generation, wireless local area networks, Bluetooth, etc. In this paper, first we introduce a novel wireless fourth generation architecture which improves cellular network capacity by reducing interference level. Second, we propose a novel approach to secure and provide seamless handoff. The proposed protocol employs mutual authentication between a mobile node and a visited access network (VAN) that is performed first by invoking the mobile node home access network (HAN) then locally without contacting the HAN.
