Interoperability in Heterogeneous Wireless Networks Using FIS-ENN Vertical Handover Model

Wireless network system aims to provide dedicated links to the users for improving the quality of services. Particularly in heterogeneous network seamless connectivity is the important requirement for the users utilizing multimedia services. Vertical handover (VH) mechanism provides uninterrupted service to the users in a multiple wireless network region by selecting the best available network. Unlike horizontal handover (one base station to another or nearby access point) VH chooses the wireless access technologies (Wi-Fi to 4G). To improve the QoS of VH model the decision phase needs efficient metrics for providing excellent service. In general a fuzzy based operating model is most suitable for decision making and to implement a seamless handover, neural network is used in the proposed research work. An experimental result describes the best decision making module by comparing the proposed hybrid model with existing models.
