A wireless sensor network based water monitoring system

Several water quality monitoring systems were proposed in literature. However, these systems are highly expensive and complex, offer inaccurate pollution positions, and do not perform auto-diagnosis to recover from faults and cope with the characteristics of the monitored environment. In this paper, we propose a novel water quality monitoring platform which combines Wireless Sensor Networks (WSNs) and Radio Frequency Identification (RFID) systems. In fact, the system uses a set of fixed RFID tags that are deployed next to the waterway and a set of mobile sensor nodes which integrate RFID readers. This platform can offer several enhancements in comparison to the existing water monitoring platforms such as: reduced cost, low energy consumption, scalability, system performance monitoring, and tolerance to errors and loss of information.
