Improvement for Throughput and Fairness in Multi-hop Wireless Ad-hoc Networks

Abstract (in Japanese) (See Japanese page) 
(in English) Using the protocol IEEE 802.11, multi-hop wireless ad hoc networks yield only a poor performance, especially in throughput and fairness. When the offered load becomes large, i.e. the system is in saturation state, long-distance flows suffer a high degree of throughput deterioration. These problems not only come from medium contention at the MAC layer but are due to the link layer. In this paper, we propose a method to solve the throughput degradation and unfairness problem by providing fair treatment between flows at the link-layer. In our proposed method, a fair scheduling algorithm using round robin queue and the estimation for the average interval of packet enqueueing is applied to alleviate the unfairness problem at both MAC and link layer. The simulation results reveal that our proposed method is able to achieve better throughput and fairness compared to the standard IEEE 802.11.
