Guaranteeing the quality of service (QoS) for real time applications is one of the challenging issues in next generation all-IP networks. Analysing the user perceived throughput is essential to measure the QoS experienced by real time applications. Medium access control (MAC) mechanism of the serving access network as well as the vertical handover (VHO) algorithm used by the mobile terminals (MTs) for target network selection have significant impact on user perceived throughput. Apart from that the upper layer mobility management protocol also influences the throughput performance considerably. The existing frameworks for throughput analysis do not adequately address the MAC specific issues. In this work, we have developed an analytical framework to analyse user perceived throughput considering the effect of both MAC specific details and upper layer mobility management protocol. Using our proposed framework, we have compared the throughput performance of video traffic application when mobile IPv6 (MIPv6) and seamless IP diversity based generalized mobility architecture (SIGMA) are used for mobility management. Our analysis reveals that the superiority of SIGMA over MIPv6 is actually conditional on the performance of the underlying VHO algorithm. Extensive simulations have been done to validate the analytical results.
