Design of a Sensor Network for Drinking Water Control in the Maria of Merced Educational Unit

Abstract:

The excessive consumption of drinking water in the María of the Merced Educational Unit brings with it the need to establish control over it, being a private entity that is located in the Portoviejo canton of the province of Manabí in Ecuador; it is here where it is proposed for this research to design a wireless sensor network over the educational institution. For this purpose, the ZigBee communications protocol was used since this technology allows creating the scope of the network, delimited by approximately 140 square meters, in addition to providing adequate management of battery performance and bandwidth. Several tree, star, and mesh topology scenarios were defined and evaluated by simulation using effective transfer rate, latency, and packet loss parameters. As a result, the tree topology is the most suitable for use in this context. To validate the results, a quasi-experiment was defined in which significant differences between the three topologies were analyzed using the Kruskal Wallis test, allowing the results to be corroborated by statistical tests.
