iHOPE: An Intelligent Handoff Protocol for Seamless Multimedia Service in Wireless Network

摘要

In this paper, we propose an intelligent hand-off proto-col(iHOPE) to support seamless multimedia stream service with less handoff latency and packet loss. In iHOPE, neighbor base stations receive media data packets from a server and transcode it for a mobile host in advance. When the mobile host enters a new cell, the base station of the cell immediately forwards the transcoded media 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.
