Supporting multimedia applications over wireless networks has become a very active research topic recently because video applications are prognosticated to receive high demand in future wireless networks, such as ad hoc networks. However, enabling video transmission over wireless ad hoc networks is more challenging than over other wireless networks due to the node mobility, interference and the lack of infrastructure. This paper addresses the problem of video transmission over ad hoc networks. We propose to combine Multiple Description Coding (MDC) with multiple source transport (Multipoint-to-Point transfer: MP2P) in order to maintain a smooth video streaming over wireless ad hoc networks. In this paper, we perform comprehensive simulation and test bed experiment in order to show the effect of the proposed MP2P video transfer with MDC for two description case on video streaming over wireless ad hoc networks. The results show that the proposed mechanism successfully improves the video transfer performance in terms of video packet reachability and throughput.
