Vertical Handoff Decision Algorithms Using Fuzzy Logic
نویسنده
چکیده
This paper reports on the design and implementation of multi-criteria vertical handoff decision algorithms in a heterogeneous wireless wide area network (WWAN) and a wireless local area network (WLAN) environment. An “IPcentric Field Workforce Automation” project aims to ensure free movement of field workers between networks while always connected in an IP mode, and to allow a user to use one device across many types of networks. This requires the integration and interoperation of heterogeneous networks, and the provision of seamless vertical handoff. We use a fuzzy logic inference system to process a multi-criteria vertical handoff decision metrics.
