Next-generation wireless networks are the promising network to provide Always Best connected network. Mobility management is the primary issue in next generation networks. Mobility management comprises of location and handoff management. When mobile user roams in the next generation networks vertical handoff is the main issue. Vertical handoff decision process can be handled by many researchers in the recent years. Vertical handoff process can split in to three phases such as handoff initiation, handoff decision and handoff execution. Initially vertical handoff initiation and decision are taken with respect to the received signal strength (RSS). Many such algorithm experiences the probability of unnecessary handover and handoff failure. In this paper we proposed fuzzy normalized Handoff initiation algorithm (FUN_HoI) module which considers the combination of different input criteria along with RSS to initiate handoff in time to reduce unnecessary handover and handoff failure probability. The special function of FUN_HoI is to take fuzzy normalization of all input criteria after fed in to the Fuzzy inference system (FIS). An importance of fuzzy normalization is to filter unsuitable candidate networks and thus improves the efficiency of an algorithm. The proposed method is compared with the existing algorithm such as RSS based and Bandwidth based algorithm. The comparative study reveals that the proposed method consumes less delay, reduced handover probability and unnecessary handoff.
