Smart Parking System using Wireless Sensor Networks

for multi-floor parking facility using WSN. The system monitors the availability of free parking slots and guides the vehicle to the nearest free slot. Additional information such as the amount of time the vehicle has been parked is also monitored for billing purposes along with the status of each mote. Cost is minimized by keeping the number of sensors lower without sacrificing the reliability. Energy consumption of each mote is kept in check by allowing the systems to sleep periodically and by reducing their communication range.
