|
Both the research community and developers in
industry have identified the need for a clearly defined
vocabulary and programming framework for location
technologies. A layered Location Stack that provides
appropriate abstractions, common terminology, and a
clear API has been proposed in the last edition of
WMCSA. This paper relates the experience gained in
applying the Location Stack abstractions to the design
and implementation of a location system using three
separate location technologies integrated in a wireless
computer. A single application interface, termed the
Universal Location Framework, is designed to
aggregate indoor, outdoor, and proximity sensor
technologies. Our focus is on how well partitioning
and parameter passing between the layers worked for
our purposes as well as identifying system
requirements not currently part of the stack. In
closing, we provide evidence in support of the Location
Stack’s usefulness and we make some recommendations
for its potential evolution.
