In this paper we study the problem of throughput maximization, with fairness guarantee, in multi-cell WLANs with hidden terminals. In such a scenario, the throughput gained by each flow is generally determined by the four major control mechanisms that make the basis of WLAN control protocols - viz., radio frequency channel assignment, association control, intra-AP airtime sharing between the associated...
In this paper we study the problem of joint client association, airtime sharing and contention resolution in IEEE802.11 multi-cell WLANs with directional antennas with the goal of achieving optimal fair throughput. We formulate the problem as a non-linear programming problem and solve it under the network utility maximization framework. Using simulation, we demonstrate that i) the association pattern...
In this paper we study the problem of client association, airtime sharing and contention resolution in a multi-cell WLAN to achieve fair download bandwidth sharing. We first model the problem as a utility maximization problem, then, because of the integral nature of association, the problem being NP-hard, we decompose it into two sub-problems: the client association problem on one hand, and the joint...
In this paper we study the problem of client association, jointly with airtime sharing and contention resolution in a multi-cell WLAN with hidden terminals with the objective of achieving proportional fair download bandwidth allocation to the clients. We first formulate the problem as a utility maximization problem, which, due to the integral nature of association turns out to be a 0–1 (NP-hard) programming...
