Application of Fuzzy Logic to Handoff Control in Cellular Mobile Communication Networks
Mobile communications area [4,6] in the past two decades was marked by an extraordinary growth rate and rapid technological advances. In the continental US alone, there are currently over 8 million cellular mobile telephone users that is forecasted to grow to more than 20 million by a turn of the century. On top of this, there are some 65 million cordless telephones and 8 million pagers in operation today. All these radio services are imposing a heavy demand on the already congested frequency spectrum. The situation is further aggravated by the emerging multimedia PCS (Personal Communications System) and wireless mobile computer networks that strive to provide a simultaneous real-time mix of interactive audio, video and data services to every person without an interruption irrespective of time and location. Such exciting developments have triggered an explosive demand for the radio capacity unprecedented in the history of telecommunications. As a result, there is a likewise upsurge of research activities in finding new techniques to improve the wireless communication system capacity in recent times.
