Novel Fuzzy model for network selection in heterogeneous network

Wireless technologies’ quality of service (QoS) is influenced by different types of networks, their factors, and their standards. The procedure of switching from one mobile station to another is known as a vertical handoff. In this paper Intelligent Vertical Handoff Decision model based on Fuzzy Logic Decision is developed, which has four parameters for vertical handoff decision : Received Signal Strength (RSS), End to End Delay, Jitter, Bit Error Rate with the help of Fuzzy Logic tool box and concept of fuzzy linguistic variable.. Performance gets better and complexity is decreased after simulation. Not only that, but compared to the conventional way, there have been fewer handoffs.
