Handoff Failure management in overlapping cellular Networks

During the past few years, advances in mobile communication theory have enabled the development of different wireless technologies. Next-Generation Wireless Systems (NGWS) integrate different wireless systems, each of which is optimized for some specific services and coverage area to provide ubiquitous communications to the mobile users. One of the most important problems in wireless networks is handoff which occurs during movement of MT (mobile terminal) from one cell to another. In this paper, we extend the handoff minimization method proposed in reference [۱] for real state that wireless cells having overlap on each other. Based on the information of false handoff probability, we analyze effects of different parameters such as rate of overlapping, signaling time delay, speed of MT (mobile terminal) and other parameters on probability of false hand off and hand off initiation probability.
