| Abstract: | Wireless ad hoc networks consist of mobile/static nodes interconnected by wireless multi-hop communication links. Unlike conventional wireless networks, ad hoc networks have no fixed network infrastructure or administrative support. Moreover supporting appropriate quality of service and fairness for wireless ad hoc networks is a complex and difficult task because of the imprecise network state information. In this paper, we evaluate IEEE 802.11 in terms of its fairness in multi-hop scenarios. Moreover we identify the reasons for the existing unfairness and then propose a purely distributed algorithm to provide fair access to all flows. Our simulation results show that our proposed protocol approximates a round robin scheduler, thereby providing considerable improvement in terms of fairness and throughput in multi-hop flow scenarios. | |
