Audio-Visual Wireless Streaming Platform for the Residential Environment Employing Mesh and MIMO Extensions

Abstract

ASTRALS is a project funded by the FP6 1ST program which focuses on the in-home delivery, adaptation and processing of multiple audio/visual streams. One aspect of this project focuses on the wireless transmission of these streams using the IEEE 802.16 standard. A premium Quality of Service and IP based transmission scheme is employed in this project including MIMO and mesh extensions for increased throughput and robustness. The MIMO architecture is based on a novel technique which maximises the performance over both Line-of- Sight and non-line-of-sight conditions. On the other hand, mesh networking is responsible for multi-hopping transmission when a direct link is not available. This paper contains a number of simulation results which imply the possibility towards fully deterministic wireless audio/visual transmission in the home environment.
