In this paper we propose an approach to increase TCP’s fairness in multihop wireless networks, using ECN as a congestion signalling mechanism. The novel idea we introduce is that the marking probability at a wireless node is a function of the aggregate utilization in the node’s neighborhood, which is determined by the sum of the receiving rates of all nodes within its collision domain. A node’s received rate can be communicated to neighboring nodes by piggy-backing it on control packets, such as CTS and RTS messages, or data packets. Simulation results demonstrate that our approach can improve TCP’s fairness in a multihop wireless network compared to drop tail queueing, while achieving the same aggregate throughput. Moreover, the proposed approach yields smaller average packet delay and delay jitter compared to drop tail queueing.
