Abstract: Solving frequency assignment problem (FAP) with multiple objectives is NP-hard. The network has many constraints to be respected when assigning frequencies. In this paper, we consider two objectives: reduce the number of frequencies and the interference caused by the violation of the network constraints. We use a new model based on a set-T-colouring graph which takes in consideration all constraints related to cellular network. We propose to use an evolutionary metaheuristic, biogeography-based multi-objective optimisation algorithm (BBMO), to solve the considered problem. As it is a bi-objective approach, our results are represented by a set of non-dominated solutions based on the definition of Pareto optimum front. A framework to study and measure the quality of the obtained Pareto fronts based on six performance indicators (ONVGR, HV, Spread, GS, GD, IGD) has been implemented. The obtained results show the efficiency of the BBMO on FAP based on a well known COST259 dataset. Moreover, a statistical analysis compares our approach BBMO-FAP to NSGA-II and identifies the best-performing method.
