Abstract: The number of mobile subscribers has been increasing at a faster pace every year. This has imparted the need on the part of network operators to provide continuous and seamless mobility with the aim “Anywhere, Anytime” services to the users. Designing a proper handoff mechanism and its implementation is the important factor to provide ubiquitous data services. A new network selection algorithm in case of heterogeneous network environment for taking handoff decision has been proposed and implemented using Fuzzy Logic. The limitation of using Fuzzy Logic for increased network metrics consideration has also overcome by using Dominant Rule Determination. Fuzzy Rule Base system with reduced complexity is developed and evaluated. The network with highest handoff score value obtained from the fuzzy system output is chosen for executing better Quality of Service (QoS) handoff.
