Abstract :
A new handover decision algorithm for microcellular systems is proposed. A handover is optimal at a cell boundary in line-of-sight situations or a street corner in non-line-of-sight situations. Since the probability of handover is maximum at these locations, it is chosen as a new criterion for processing a handover. The method is based on the real-time computation of the probability of handover from the received signal strengths, and on tracking its global maximum by calculating its gradient. Simulation results of the proposed algorithm are presented and the performance of the method is discussed
