Abstract(in English) | As a scalable access netwok to the Internet, we have studied the Wireless Internet-access Mesh NET-work (WIMNET) that is composed of multiple access points (APs) with multihop communications. In WIMNET, the throughput shortage can be caused by interferences among communication links between APs, and the thoughput unfairness between APs can be caused by the difference on numbers of hops from APs to the gateway. As a solution to these problems, we have proposed the contention window (CW) size control method in CSMA/CA protocol, and have evaluated it through simulations. In this paper, we evaluate the effect of our proposal through throughput measurements in real environments after implementing it on a Linux-PC. Our results show that the optimal CW size is actually different depending on the number of APs in WIMNET, and there is a trade-off between the increase of the average throughput and the fairness of the throughput between APs. |
