AN EFFICIENT TRANSPORT SCHEME FOR MULTIMEDIA OVER WIRELESS INTERNET

Multimedia transmission over wireless Internet is a challenging work since the random errors frequently occurred in the wireless links heavily deteriorates the performance of traditional transport protocols such as TCP and UDP. This paper presents a new scheme for delivering multimedia over a connection of which only the last hop is wireless link. Simultaneously error control and congestion control are addressed in this wireless Internet platform. The packet loss caused by Internet congestion and wireless error can be differentiated in our scheme. Fading and high bit error rate (BER) on the wireless link as well as congestion in the wired network are separately controlled. Simulation results demonstrate that the proper congestion control and error control can improve throughput of the connection and the end-to-end quality of delivered media.
