Abstract:
In mobile ad hoc networks, achieving good QoS is a critical issue and is very difficult to guarantee due to rapidly changing of network topology and the lossy nature of wireless links. In this context, routing protocols must be smart enough to select better paths for data transmissions. In this paper, we focus on the well-known Ad-hoc On-demand Distance Vector (AODV) protocol. Standard route discovery approach used in AODV is expected to obtain the best path in term of delay. However, in lossy-links context, multimedia data packet transmission success, on path established thanks to control packets, may require several attempts. These retransmissions increase delay and overhead. Many QoS-based methods failed to make a meaningful improvement due to added complexity and additional delay and overhead. In this paper, we use a metric based on number of Packet Retransmissions to show that improving performance of on-demand routing protocols, in the mobility context, lies on effective control of node neighborhood.
