QoS based Vertical Handover Decision Algorithm using Fuzzy Logic

With increasing number of emerging real time mobile applications, the Quality of Service of networks becomes an important decision criterion for handover. Mobile users aspire to keep their ongoing open mobile applications alive while moving across various wireless networks. Hence Vertical Handover between Wireless networks is required for the seamless and continuous use of applications when the user is moving. In this paper, we have presented a Vertical Handover Decision Algorithm with input parameters as Received signal strength, Bandwidth, Network Coverage and Quality of Service.
