A quality of service-aware routing scheme for multimedia streaming in wireless cabin environments

Abstract

The advent of efficient video compression algorithms and the increase in the data-rate handling capabilities of wireless standards facilitate multimedia streaming over wireless networks. The Quality of Service (QoS) of this application heavily depends on the number of lost packets and the end-to-end delay. Various studies have proposed solutions and analysis on the bandwidth constraints, but too little effort has been directed towards the improvement in video quality by ensuring a higher success rate of the transmitted multimedia packets in adverse channel conditions. In this paper we propose such a solution in a wireless cabin environment. The algorithm determines the better channel conditions between direct routing from the server to the mobile station and one hop ad-hoc routing by analyzing the number of successfully transmitted packets. The selected solution is then used for transmission of subsequent multimedia packets until the performance degrades, reinitiating channel selection.
