Wireless Sensor Network Prototype for Solid Waste Bin Monitoring with Energy Efficient Sensing Algorithm

摘要

This paper presents a novel prototype of solid waste bin monitoring system using wireless sensor network which can respond as soon as someone throw waste insight the bins. The system architecture uses ZigBee and GSM/GPRS communication technologies and a set of carefully chosen sensors to monitor the status of solid waste bins in real time. The system is composed of three tier structure such as lower, middle and upper tier. The lower tier contains bin with sensor node installed in it to measure and transmit bin status to the next tier, the middle tier contains the gateway that stores and transmits bin data to control station and control station resides in the upper tier that stores and analyze the data for further using. An energy efficient sensing algorithm is also used in the first tier to collect the bin parameters. In this way, the system can help to minimize the operation costs and emissions by feeding the collected data to a decision support system for route optimization.
