| Abstract | The IEEE 802.11 standard is often considered as the underlying wireless technology used in multihop wireless networks. The use of this standard in these networks raises some issues in terms of efficiency and fairness. These issues come mainly from the MAC protocol of 802.11. An approach is to propose an alternative to this MAC protocol in order to solve or decrease these problems. But it should probably take some time before new wireless network cards be based on these solutions. Another approach is to consider that IEEE 802.11 will be the wireless local technology for a while and that the solutions should be designed above. In (VAN 08), we describe a simple bandwidth allocation algorithm that is distributed and dynamic. This algorithm is based on a simple wireless medium model. In this article, we derive a throughput regulation protocol from this algorithm for multihop wireless networks. This protocol, called Profiterole, is distributed, asynchronous, dynamic and uses few control information. Then, we give a detailed evaluation of Profiterole thanks to NS2 simulation results. We also compare it with DiffQ, a new and recent congestion control algorithm for multihop wireless networks. MOTS-CLES : reseaux sans fil multisauts, 802.11, controle de debit, equite |
