The next generation mobile networks have the development trend of integration of cellular networks and Wireless Local Area Networks (WLANs). Considering the heterogeneous environment, Universal Mobile Telecommunication System (UMTS) of cellular technology and WLAN (over IEEE 802.11) are the most promising networks. Integration of these two networks facilitate user for the seamless communication. Handoff decision making is the main challenging issue in the integration of UMTS and WLAN networks. Efficient vertical handoff algorithms are required to maintain the acceptable level of quality and seamless connectivity in heterogeneous wireless environment.
