Among the challenges that we face in our day to day life one of the most unavoidable challenge is parking our car wherever we go. As our need increases our travelling increases but due to drastic increase in usage of automobiles and increased population we face the tough task of parking our car particularly during the busiest hours of the day. During peak hours most of the reserved parking area gets full and ultimately the user has to search for his/her parking among other parking area creating more traffic and leaves them with no indication on the availability of parking space. To overcome this problem there is a need of a designed parking in commercial environment. The aim of this paper is to propose a design of a smart car parking system commanded by an android application that reserves the parking slot in the parking area and displays the availability of parking slot in the parking area on the lcd display.
