Abstract:
|
This article presents a statistical study on the
availability of location sources. In particular, it rates the
availability of cellular network base stations and GPS satellites
in urban scenarios. Individual and joint availability density
functions have been obtained for both types of signal sources,
as well as statistical information that complements these
functions. This information is of great importance due to the
growing interest in fusion (i.e., combination) of location
techniques. The results indicate that the improvements in
coverage from fusion techniques depend both on the fusion
mechanism and the scenario, obtaining noticeable benefits in
constrained situations. |
