Literature Review of WSN MAC Protocols in Smart Parking

摘要

As the urban population increases the urban density becomes denser. The first to be affected is the traffic, 30% of traffic is caused by vehicles cruising for parking. One of the solutions is to deploy a smart parking assisted by Wireless Sensor Network (WSN), thus the cities can optimize parking re-sources and provide a transparent and smart services. Drivers can get real-time parking availability information through their smartphone. The aim of this paper is to introduce an intelligent parking system based on WSN by identifying their benefits, challenges and constraints while providing real-time availability information. We will focus on the WSN MAC layer and protocols proposed. We start with a state of the art of smart parking solutions based on WSNs and their politics to solve the current parking problems. Then we discuss the different solutions of MAC protocols proposed in real time service context and we finish with a comparative of these solutions to identify their strengths and limitations.
