An intelligent handoff protocol for adaptive multimedia streaming service in mobile computing environment

Abstract

In this paper, we propose an intelligent hand-off protocol for adaptive multimedia stream service in mobile computing environment. In this protocol, the neighbor base stations receive media packets from a server in advance and transcode it to be suitable for mobile host. So, when a mobile host enters the neighbor cell, the base station immediately forwards the transcoded data packet to the mobile host. This paper describes the intelligent handoff protocol and the media data transcoding mechanism. We evaluate our approach with simulation results. © Springer-Verlag Berlin Heidelberg 2004.
