Abstract

Mobile Ad Hoc Networks (MANETs) and Vehicular Ad Hoc Networks (VANETs) as mobile wireless networks are challenging environments as there is no centralized packet routing mechanism. Packet delivery is normally multi-hop and may encounter out-of-range intermediate network nodes on the routing path. There may be problems of energy consumption in MANETs and of constrained routing paths in VANETs. Consequently, introducing real-time video streaming into these environments is problematic. Peer-to-peer (P2P) streaming from multiple sources is a way of strengthening video streaming in these circumstances. In this chapter, P2P streaming is combined with various video error resilience mechanisms that mostly take advantage of the multiple paths available in such networks. As video streams are sensitive to errors the impact of wireless channel errors should be assessed and, for VANETs, realistic mobility models should be modeled, especially in urban settings. The chapter looks in detail at how video source coding can assist in the protection of video streams, in that respect comparing various forms of multiple description coding.
