An Approach for Cell Assignment in UMTS Networks

This paper proposes a new mathematical formulation to address the problem of cell assignment in UMTS network. To solve the problem, an adaptation of the tabu search metaheuristic is proposed. In this adaptation, applicable movements are well defined in order to efficiently explore the search space. Each movement has an associated gain that helps assess the degree of improvement of a current solution. Simulation results enable to evaluate the heuristic parameters that give the best solutions.
