Abstract

IEEE 802.11 is often considered as the underlying wireless technology of multihop wireless networks. But the use of 802.11 in such networks raises issues, like efficiency and/or fairness issues. In this article, we propose a distributed and dynamic rate allocation solution that is based on a simple radio sharing model. Due to its simplicity, we can derive a network protocol that can be practically used in multihop wireless networks. This protocol provides a fair bandwidth sharing between end-to-end flows, while maintaining an efficient overall throughput in the network. This solution has been implemented in NS2 and evaluated by simulations.1
