ABSTRACT

Recent years in the field of mobile communications have brought two significant requirements – seamless service delivery and Quality of Service provisioning. Seamless mobility goes hand in hand with Mobile IPv6 protocol and various handover schemes of this protocol are trying to solve the QoS issue. In this paper we are presenting a method for evaluation of the Layer 3 handover schemes from the handover latency point of view. A L3 handover procedure can be divided into four phases: Movement Detection, CoA Configuration, Home agent Registration and Route Optimization. We simulated the proposed protocol certificate based on Demand Approach in Route Optimization phase and compared it with the return routability procedure in Route Optimization phase of MIPv6 handover. The latencies in different handover phases have been measured in an operated wireless LAN (WLAN) in order to determine the performance bottleneck of handover.
