In this research, we use Artificial Bee Colony (ABC) algorithm tosolve cell to switch assignment problem (CTSAP) that is NP-hard. InCTSAP, there are cells and switches in which cells locations arepredetermined. The objective of problem is optimal assigning of cellsto switches with minimum cost. Here, we have two kinds of costs,handoff and cabling costs. Call handling capacity for every switchesare given and equal. The model of our work is single homed that iseach cell must connect to only one switch. The mathematical model isbinary and nonlinear.The program is coded by MATLAB 7.8.0 (R2009a). After estimatingparameters values of model, approving performance accuracy of codeand adjusting control parameters, the efficiency of algorithm bydetermining experimental problems compared to Ant ColonyOptimization (ACO) that is one of the best for solving this problem.Results show satisfactory performance of ABC algorithm
