2011 – 2019 - Biodiversity and Computing - Subproject 1. Sensor networks applied to agrobiodiversity.

• Coordinator: Antonio Mauro Saraiva
• Description: The general objectives of the project are: (i) to conduct cutting-edge research in monitoring and control based on the use of large-scale sensor networks, through a collaborative network of researchers; (ii) to investigate and develop the best and most appropriate techniques for monitoring, control, information processing and data fusion for application in large-scale sensor networks; (iii) to provide training for young researchers in sensor networks; (iv) to disseminate research results; (v) to generate and exploit patents; (vi) to demonstrate the benefits of sensor networks to society through practical applications in environmental monitoring and precision agriculture.

2011 – 2013 - Security in Wireless Sensor Networks.

• Coordinator: Cíntia Borges Margi
• Description: Wireless networks in general are valuable technologies for developing applications in various areas, from environmental monitoring to social networks. Wireless sensor networks, in particular, have peculiar characteristics such as limited power sources and computational resources. Several applications require security services, such as authenticity, confidentiality, and, in general, data availability. The focus of this project is the development of security mechanisms for WSNs. Two main aspects will be addressed: (i) development of a security architecture, focusing on the application layer, and (ii) investigation of new ways to maximize data survival using cryptographic algorithms. A security architecture for WSNs that operates at the application layer of the OSI model protocol stack allows for greater flexibility regarding the use of various cryptographic keys related to network groupings. Furthermore, it enables the switching of security levels at runtime and portability between platforms or operating systems. The data survival service becomes relevant in WSNs where the base station is itinerant, and therefore not always available to obtain data from the sensor devices.

2009 – 2010 - Wireless Sensor Networks.

• Coordinator: Cíntia Borges Margi
• Description: Research in wireless sensor networks, addressing aspects of power management, protocols, applications, and security.

2004 – 2006 – Meerkats.

• Coordinator: Roberto Manduchi
• Description: Specification and implementation of a visual sensor network testbed, called Meerkats. The Meerkats testbed node is based on the Stargate platform, in addition to an 802.11 wireless network card and a Logitech QuickCam camera. The node is powered by a 2-cell Li-Ion battery (7.4 V), which is connected to Stargate via a 5 V output voltage regulator. The operating system running on the node is Stargate 7.3, which is based on Linux.
