Abstract
In paper [2] and [3], we have studied the throughput and stability of forwarding queues in a wireless ad hoc network with random access channel. In this paper, we are focusing to draw benefit from the interaction of the MAC (governed by IEEE 802.11 or slotted aloha) and routing by defining a new cross-layer scheme for routing based on the limit number of retransmission. By adjusting dynamically and judiciously this parameter in a saturated network, we have realized that both stability and average throughput are significantly improved in linear symmetric networks: a gain of 100 % can be reached, while in asymmetric networks, we achieve a better average delay (resp. throughput) for each connection without changing the average throughput (resp. delay). A detailed performance study of our new scheme is presented using analytical and simulation evaluation.
