Performance Behavior of MANET with a Fixed Long Delay Satellite Link

In this paper, we present our observations and analysis of traffic patterns, loss behavior, throughput analysis and delay behavior of an emergency response network which could be implemented very quickly and efficiently in disaster-affected areas. We collected the audio, video, broadcast packet data of various durations on fixed end-nodes and relay-nodes. We analyze and present our observation results in terms of traffic volume, throughput analysis, loss and delay behavior. As expected, a significant amount of packet loss in long delay and narrow satellite channel was apparent. From the data collected, it was noticeable that the loss becomes more severe with bursty behavior of the traffic. We show an analysis of throughput of the network, including per flow and per hop basis. The result suggests that we should not use more than three hops for any multimedia communications over a MANET and satellite channel.
