In this paper, we present PGS, a parking guidance system based on wireless
sensor network(WSN) which guides a driver to an available parking lot. The
system consists of a WSN-based VDS(vehicle detection sub-system) and a
management sub-system.
The WSN based VDS gathers information on the availability of each parking lot
and the management sub-system processes the information and refines them
and guides the driver to the available parking lot by controlling a
VMS(Variable Messaging System).
The paper describes the overall system architecture of PGS from the hardware
platform to the application software in the view point of a WSN. We
implemented the WSN based VDS of PGS and experimented on the system
with several kinds of cars.
The experimental results show that PGS succeeds in detecting various kinds
of cars and the predicted battery life-time using measured current profiles is
over 5 years.
