Abstract:
This paper reports on the design and implementation of
multi-criteria vertical handofJ 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 handofJ. We use a
fuzzy logic inference system to process a multi-criteria
vertical handofJ decision metrics.
