Simulation-based performance comparison of video transmission over MIPv6, FMIPv6, HMIPv6, and FHMIPv6

There has been a recent trend towards an all-IP network as it provides for cost-savings together with optimized network and ease of use. Owing to explosive growth of wireless users and growing demand of wireless services, the internet body IETF has developed mobility management schemes to enhance IPv6 in mobility scenarios for wireless subscribers. These IPv6-based mobility management schemes adversely affect the performance of transport protocols during handoff. In this paper, the performance of video transmission over MIPv6 and recent MIPv6 enhancements, namely, FMIPv6, HMIPv6, and FHMIPv6 is compared. We consider the impact of different parameters like degree of mobility, wired link delay, jitter, error rate, and throughput. Due to the complexity of the required study, simulation is chosen as the most suitable analysis method. The results in this paper are based on simulation experiments performed within the ns network simulator. The simulation environment allows us also to investigate the behavior of the protocol in many cases, e.g., under channel saturation conditions, and considering different traffic sources: CBR, Video, VoIP and TCP.
