A new prototype of smart parking using wireless sensor networks

In this paper we present an outdoor smart parking prototype using wireless sensor networks as a possible solution to solve the problem of parking, through an application that present the information in order to find free parking spaces in real time, this system can help to improve the quality of life in smart cities, because the time for finding a free parking space could be reduced, as well as help to reduce pollution and to improve vehicular traffic. The use of a wireless sensor networks allow for easy installation outdoor, the system could use a solar panel to charge the batteries and being independent of an external power source wired or constantly replacing batteries. The vacancies spaces are presented to users through a smart device. The main results show a reduction of 50% of time to obtain a free parking space, a reduction in fuel consumption, and an estimated reduction of vehicle pollution. Finally, we determine for our campus university the fuel saved were 2,71 galons/year/vehicle.
