This paper presents experiments on the performance and the viability of the AODV protocol (Ad hoc On-demand Distance Vector protocol) in multi-hop ad hoc networks, for use with multimedia traffic. This type of traffic presents some particular characteristics which make it difficult for AODV to serve fluently and reliably. After this experimental study of the problems that may arise in this type of communication and its origins, we conclude that better performance is possible with the

Applying these changes, experimental tests show an improvement in the performance of the protocol with video streaming. Index Terms-AODV, multi-hop, ad hoc networks, video streaming, multimedia. 1 Parameters recommended by CISCO: error rate (5% in video-streaming and 1% in VoIP); latency (up to 4 seconds in video-streaming and 150 ms in VoIP); throughput (21 -320 Kbps in VoIP, and depending on the coding in video-streaming); and jitter (30 ms in VoIP, and insignificant in videostreaming depending on the buffering capacity).
