An interactive shopping cart to enable context
aware environments within large commercial areas is presented.
A wireless sensor network was designed, with specific nodes
embedded within the shopping carts and infrastructure nodes in
the shopping area. Due to the complexity of wireless propagation,
given the large amount of obstacles and the inclusion of users, an
in house deterministic method based on 3D Ray Launching was
employed, providing results in terms of adequate transceiver
deployment to minimize interference, energy consumption and
maximize data throughput. The proposed system was tested in a
real commercial scenario, with the implementation of an ad-hoc
monitor shopping application, exhibiting successful detection
rates in order of 99%. The proposed systems provides an
interactive shopping experience for users as well as for
commercial managers.
