AROSP: Advanced Route Optimization Scheme in PMIPv6 Networks for Seamless Multimedia Service

In standard Mobile IPv6 networks multi-media streaming suffer from packet disruptions and packet loss resulting from high handover latency as well as available bandwidth fluctuation. To decrease high handover latency, Fast Handover for MIPv6 can be adopted where the client stores quickly sufficient amount of stream in advance. However, under the both conventional protocols which based host mobility, handover latency may take up to several seconds, it is extremely difficult to maintain seamless media playback. For network-based mobility management, the Internet Engineering Task Force (IETF) is standardizing Proxy Mobile IPv6 (PMIPv6). In this paper, we propose an optimal fast handover scheme using Optimal Proxy Binding Update and Snoop mechanism in network based proxy Mobile IPv6 networks, and we then evaluate it against IETF's convention protocols in terms of deployment, proceeding latency.
