Abstract
Processing handoffs is an important task in any cellular radio system. Handoffs must be performed successfully and as infrequently as possible, and be imperceptible to the users. In order to meet these requirements, system designers must specify an optimum signal level at which initiate a handoff. Once a particular signal level is specified as the minimum usable signal for acceptable voice quality at the base station receiver, a slightly stronger signal level is used as a threshold at which a handoff is made. This margin, given by Δ= P r handoff – P r minimum usable, cannot be too large or too small [1]. Therefore, Δ is chosen carefully to meet these conflicting requirements. Handover Controls an essential component of radio resource management that imposes considerable signaling load on the network. The amount of undesirable signaling load depends directly on the speed of the hand set. In this paper, we propose that an handoff can be initiated by measuring parameters like link quality, location of the mobile and signal power w.r.t neighboring base station using Fuzzy Logic. This method will prevent the unnecessary handoff between the base station in turn reducing the burden of the base station & preventing traffic conjunction.
