Towards a water quality monitoring system based on wireless sensor networks

This paper represents the initial steps in the development of a drinking water quality monitoring system. This system is based on a wireless sensors network to detect and locate in real time any change in water quality, quantify its importance, evaluate its consequences and determine the most appropriate actions to be taken to limit its effects. First, we start with determining an optimal location of the quality control points of the drinking water. Then, we move on to the development of an anomalies detection algorithm which detects the contamination and malicious acts in the drinking water distribution system. Finally, taking into account the environmental parameters of our system, we propose a data aggregation method in order to minimize the energy consumption of the source nodes and to reduce the network load.
