Abstract

We study the interaction between rate control and medium access control in wireless networks.We start out by developing a discrete time model for the interaction of TCP Renorate ontrol and IEEE 802.11 medium acess control. Considering the operating point of the system, we obtain the well-known characteristics that the throughput decreases as the number of nodes in the network increases and that IEEE 802.11 does not provide per-flow fairness. We then propose and study alternative rate and medium acess control schemes which allow to offer per-flow fairness, as well as provide a stable and predictable throughput as the number of nodes increases.
