In this paper, we propose an optimization model for solving the channel assignment problem in multi-cell WLANs which is based on maximizing the minimum distance between access points that operate on the same channel. The formulation of the proposed model is presented in the form of a mixed integer linear program (MILP). The main advantage of the proposed algorithm is that it guarantees non-overlapping channel assignment without measurement overhead. The proposed algorithm can be implemented in real time. Simulation results show that the proposed algorithm provides better performance compared to the pick-first greedy and the single channel assignment methods.
