A Simulation Study on Multipoint-To-Point Video Streaming Over Mobile Ad Hoc Networks

Supporting video applications over infrastructureless mobile ad hoc networks is more challenging than over any other networks due to the absence of fixed infrastructure and rapid changes in network topology. In this paper, we tackle this problem by adopting the concept of multipoint-to-point (M2P) video transmission together with multiple description coding (MDC) scheme. Some modifications have been introduced considering the differences between wired and wireless networks and the dynamic source routing (DSR) protocol is extended accordingly to support M2P video transmission. Simulation study is carried out using NS-2 to demonstrate the performance of the proposed mechanism as compared to point-to-point transmission and the original dynamic source routing protocol. We show that the proposed mechanism outperforms the conventional point-to-point transmission, especially at high mobility
