Building a multi-hop wireless sensor network for water level monitoring. Repositório Alice
YANO, I. H.; ALVES, J. R.; DEMANBORO, A. C..
Abstract-Wireless Sensor Networks (WSN) are very useful for data acquisition in harsh environments or where the maintenance of wired infrastructure would not be viable. Despite of these advantages WSN nodes have a limited range ratio thus to collect data on long distance is necessary to construct a path with many relay nodes to reach the destination. Another limitation of these networks is that they often rely on batteries to operate, which can cause a serious limitation in the network lifetime. In this work it was developed a solution based on a Multi-hop WSN to collect data on long distance, and, also some strategies such as 'sleep schedule', 'data aggregation' and 'hub polling' were implemented to extend the WSN lifetime. This could be done by...

Wireless sensor networks for measuring the consumption of save water taps. Repositório Alice
YANO, I. H.; OLIVEIRA, V. C. de; ARAUJO, E. V. de; CAMPAGNUCI, A. G.; FABIANO, B.; DEMANBORO, A. C..
Currently, water consumption is on the agenda of most organizations around the world. Beyond the environmental benefits for a better use of natural resources there is also a financial motivation to continuously reduce operation costs. This study reports a cost-effective solution using a Wireless Sensor Network (WSN) for measuring the consumption of different types of save water taps, in a real situation of intense use. It is also pointed out that WSNs are networks suitable for data collection where a wired infrastructure for data transmission does not exist or it is unfeasible to install one. Which was the case of this research, that regarded the liquid consumption along with the technical and economic benefits of save water taps. On this proposed setup...
