Real-time Video Streaming Over Multi-hop Ad-hoc Networks

Since the advent of ad-hoc networking, it has been viewed as a potential multi-application technology. It holds promise for a number of fields like military, medical, logistics and disaster recovery applications. Ad-hoc networks have been an object of interest and research not just because of the prospects they offer but also because of the numerous issues that they face. One such issue is the distribution of high bandwidth real-time data via multicasting. This paper presents a comparative study of multicasting of video and video-like data using two different ad-hoc routing protocols, viz. OLSR and PUMA. Our NS2 simulations show that OLSR produces higher throughput and lower latency.
