Abstract :
One way of improving the performance of cellular networks is to build a second layer of macrocells on top of the microcell level. The system performance can further be increased by using guard channels and allowing calls to overflow to the upper layer when needed. In this study, we used simulated annealing (SA) to determine the design parameters of two-tier cellular networks for which the cost is minimized. We experimented with the SA-based technique on different example problems and obtained promising results
