Robust Cellular connectivity-Based Smart LED Street Lighting System: A Platform For Innovative Mission Critical Smart City IoT Applications

The study computes the availability of street lighting system in Warri. This system under study consists of subsystems that are known as workstations. A generator and sets of street light make up a workstation. The power source and the street lighting were modeled into series and parallel combinations. Reliability Block Diagrams and Path Tracing Method were employed assuming independent failure of the components. The availability of the set of street lightings, workstations and hence the availability of the system were determined. Results of the study show that users in Cemetery road had the least availability of 62.19% for the period. The implication is that users travelling along this road experienced wide variation of light that could lead to accidents. Keywords: Availability, Street Lighting and Reliability block diagram

<p class="0abstract">IoT concept gained tremendous momentum in this century's technological advancements because it has efficiently connected various devices wirelessly. The ESP8266 Wi-Fi serial transceiver module is one of the most used devices for IoT applications. This paper designs the IoT-based smart street lighting system using ESP8266 configured as a Mesh network. The ESP8266 was instructed (programmed) to control the light level by producing a PWM signal, then it sends a dimmer value and reads the sensor's data. We can access our system wirelessly via a web server. The overall system was successful as a smart street lighting system in a wireless Mesh environment. This research result is also compared to the existing similar project in terms of the system complexity aspect.</p>

The Monte Carlo Method

The article has considered the calculation of the unified glare rating (UGR) based on the luminance spatial-angular distribution (LSAD). The method of local estimations of the Monte Carlo method is proposed as a method for modeling LSAD. On the basis of LSAD, it becomes possible to evaluate the quality of lighting by many criteria, including the generally accepted UGR. UGR allows preliminary assessment of the level of comfort for performing a visual task in a lighting system. A new method of "pixel-by-pixel" calculation of UGR based on LSAD is proposed.
