Distributed smart street LED lights for human satisfaction in smart city: student research abstract

In this paper, we proposed a cost-effective solution to use Light Emitting Diode (LED) street lights for multi-purposes rather than their basic lighting purpose while generating various useful light patterns. The generated patterns help citizens in 1) guiding them about the safe route in case of any event, emergency, or any disaster like a fire or flood 2) conveying them any message or information 3) providing them entertainment or fun, etc. We have developed an API for Intel-Edison platform that can generate thousands of dynamic light patterns while working with colors, light intensity, blinking rate, and delay. The LED lights are distributedly connected via Wi-Fi by providing P2P as well as central communication between them. The challenges of managing delays between light switching and offering time synchronization are accomplished by deploying Precision Time Protocol (PTP). We evaluated the system with a user study as well as by the system response time.
