Fairness in Double Star Ad Hoc Networks

In an ad-hoc network, communications in the half duplex mode imply that the nodes in the Ad-Hoc network have not always fair access to the network resources. In this paper, the fair resources allocation for nodes in a double star is studied. The aim of this work is to analyse the fairness behaviour of the number of packets received by each node. A theoretical study shows in which case we can obtain fairness. Some implementation with NS2 (ns-2.31 version) enables to validate our approach and some simulations are used to illustrate a way to achieve fairness in the network by controlling the flow rates of the network.
