Globally optimized dynamic channel assignment for cellular radio systems

This paper presents a new channel assignment strategy named globally optimized dynamic channel assignment (GODCA). The GODCA differs from other strategies by consistently keeping the system in the utmost optimal state. The algorithm is simple and straightforward. It employs the Hopfield neural network for optimization which avoids the complicated assessment of channel compactness and guarantees optimum solution for every assignment. The analysis and simulations show that the GODCA algorithm can attain low blocking probability disregarding the traffic density of the system, hence, it has better performance than the conventional fixed and dynamic channel assignments
