In order to tackle the second issue, Wireless Sensor Networks (WSN) have been proposed to provide updated information at a relatively low deployment cost.
Due to advances made in wireless computing, sensing devices and small batteries, a wireless sensor network can be defined in terms of its low-cost and low energy consumption, regardless of external services.
This makes it possible to monitor distinct variables of interest like the level of pollution in the river.
This network generally consists of a range of sensor nodes installed in different locations, which are designed to gather and transmit specific data
through short-range wireless interfaces to a base station. To carry this out, the architecture of the nodes is equipped with low-power wireless networking technologies and simple sensors.
