Abstract

In this paper, we consider multicast video clip streaming in an ad hoc network. Efficient delivery of video is accomplished by means of a Peer-to-Peer (P2P) overlay network. To exploit multipath transport the paper introduces layered video streaming without the need for base layer protection. In an urban environment with higher node densities and lower node speeds, the network performance is shown to be stable and superior compared to single-layer distribution. Detailed analysis confirms the results predicted by summary statistics. Heterogeneous wireless networks are targeted in which ad hoc networks relieve cellular wireless networks.
