On routing Web and multimedia traffic in mobile ad hoc networks
T.D. Dyer, Rajendra V. Boppana · 2003
We evaluate the capabilities of MANETs in supporting multiple, simultaneous HTTP and multimedia streaming flows. The HTTP traffic is produced by several Web servers, each responding to a series of concurrent requests from multiple Web clients, and multimedia traffic is modelled as a variable bit-rate stream consisting of UDP packets. To see the impact of a routing protocol, we consider two on-demand (AODV and DSR) and one adaptive proactive (ADV) routing protocols. We also consider the impact of a previously proposed TCP-sender heuristic, fixed RTO, on HTTP performance. Our results indicate that ADV performs well relative to the on-demand techniques, providing higher throughput for variable bit rate UDP traffic and significantly reducing the time required to complete Web client-server transactions. Furthermore, our results show that, compared to TCP Reno alone, the fixed RTO technique yields significant gains in the HTTP performance of the two on-demand algorithms.
