Enhancing the quality of service of video streaming over MANETs using MDC and FEC

摘要

Path and server diversities have been used to guarantee reliable video streaming communication over wirelessnetworks. In this paper, server diversity over mobile wireless ad hoc networks (MANETs) is implemented. Particularly,multipoint-to-point transmission together with multiple description coding (MDC) and forward error correction (FEC)technique is used to enhance the quality of service of video streaming over the wireless lossy networks. Additionally, thedynamic source routing (DSR) protocol is used to discover maximally disjoint routes for each sender and to distribute theworkload evenly within the MANETs for video streaming applications. NS-2 Simulation study demonstrates thefeasibility of the proposed mechanism and it shows that the approach achieves better quality of video streaming, in termsof the playable frame rate, reliability and real-time performance on the receiving side.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
