Abstract

Nowadays, the importance of wireless technologies is increasing rapidly. Next generation wireless networks concept proposes a heterogeneous structure, consists of different wireless technologies, in order to provide quality of service (QoS) supported and cost efficient connections at anywhere and anytime. Since different wireless technologies overlap with each other, one of the most challenging topics for next generation wireless networks is handoff. Several parameters, pertaining to user/application requirements and network conditions, such as; data rate, service cost, network latency, speed of mobile, and etc. must be considered in handoff process of heterogeneous networks along with RSSI information. In this paper, an adaptive fuzzy logic based vertical handoff decision making algorithm is presented for wireless overlay networks which consist of GSM/GPRS/Wi-Fi/UMTS/WiMAX technologies. Data rate, monetary cost, speed of mobile, battery level and RSSI parameters are considered as inputs of the proposed fuzzy based system. The results show that, proposed adaptive fuzzy based algorithm can provide enhanced outcomes for both user and network.
