| description |
Cellular networks are more and more complemented by wireless LAN
hotspots. However, when users are mobile, the small coverage area of
hotspots is a challenge for the access network discovery and
selection. Network selection mechanisms can be improved if, in
addition to terminal-based measurements, hotspot information can be
retrieved from an information service. In this context, the coverage
area is one of the most important characteristics of hotspots. This
paper studies algorithms for the precise estimation of hotspot
coverage areas based on field strength measurements performed by
individual terminals. Different approaches for interpolation,
vectorization and complexity reduction of measurement data are
presented and evaluated in different scenarios by means of
simulation. As a result, guidelines for the optimal parametrization
of these algorithms are presented.
