Abstract

This paper presents a novel middleware architecture in order to support multimedia services across inter-technology nodes in a seamless manner and with minimum perceived QoS degradation. The proposed architecture is based on the Media Independent Handover (MIH) framework. The novelty of the proposed architecture is based on a number of enhancements on top of the original MIH scheme. Firstly, the handover decision function is based on triggering/collecting statistics from physical, network and application layer, so that an ongoing multimedia session (video) can be transferred seamlessly. Secondly, the original MIH scheme is coupled with a novel mechanism that updates the video encoding parameters in real time, allowing video QoS adaptation and/or video QoS based vertical handover based on an estimated value of the current Peak Signal to Noise Ratio received by the mobile user. The simulation results carried out with the NS-2 tool parametrized for supporting MIH functionality and H.264 encoded video traffic, have shown a significant improvement both in the received video QoS in terms of PSNR and the network throughput, during WiFi to UMTS handover, under the proposed scheme.
