IoT enabled waste management system using ZigBee network

With rapid urbanization, industrialization and population growth in India, solid waste management is becoming the key challenge for state governments and local municipal bodies. The garbage containers that are placed at public places are found to be overflowing frequently due to increase in the daily waste disposal. In this research, IoT (Internet of Things) enabled waste management system using ZigBee network and MQTT (Message Queue Telemetry Transport) protocol is proposed to determine filled status of the garbage container. The data acquisition module placed within the container updates the server via ZigBee coordinator, whenever the level of the garbage reaches the threshold. MQTT is a lightweight protocol and it provides the communication link between coordinator and the server. Optimal path for collecting the filled containers is determined in the server using Haversine formula and travelling salesman algorithm. The information is intimated to the garbage collection unit through Telegram messaging application to minimize time and fuel cost.
