Given the importance of climate changes and their potentially dramatic consequences for human beings, designing precise and reliable evolution models is of prime importance. Unfortunately, current data collection techniques are rather limited as they make ...
Wireless sensor networks (WSNs) can be a valuable decision- support tool for farmers. This motivated our deployment of a WSN system to support rain-fed agriculture in India. We defined promising use cases and resolved technical challenges throughout a two- ...
Wireless sensors are small devices that are able to gather, process and deliver information from a physical environment to an external system. By doing so, they open new applications in different domains, such as healthcare, traffc control, defense and agr ...
