QoE Provisioning and Seamless Mobility Management based on PMIPv6 Protocol

The efficient mobility management is a key factor to the success of mobile multimedia applications. In particular, the IETF (Internet Engineering Task Force) has proposed a new protocol named PMIPv6 (Proxy Mobile IPv6) in which mobility management is not delegated to the terminal, as done by the Mobile IP, but to the entities belonging to the network provider. This paper describes and evaluates an implementation of PMIPv6. The performance study is carried out through an IEEE 802.11 testbed considering QoS (Quality of Service) and QoE (Quality of Experience) metrics in order to evaluate the PMIPv6 support for multimedia traffic. Furthermore, we propose an optimization based on the received signal strength by the terminal in order to anticipate the handoff procedure.
