2007 14th IEEE International Conference on Electronics, Circuits and Systems, 2007
In this paper we present an overview of the sensor network architecture as developed in the ANGEL project. We first specify the particular requirements found in healthcare and assisted-living applications, then introduce the general reference architecture and finally discuss some security-related aspects.

Viticulture Zoning by an Experimental WSN
International Journal of Information Technology and Web Engineering, 2009Biological research in agriculture needs a lot of specialized electronic sensors in order to fulfill different goals, like as: climate monitoring, soil and fruit assessment, control of insects and diseases, chemical pollutants, identification and control of weeds, crop tracking, and so on. That research must be supported by consistent biological models

ES-WSN: Energy Efficient by Switching between Roles of Nodes in WSNs
2015 IEEE Global Communications Conference (GLOBECOM), 2014The objective of our work is to propose a new approach called ES-WSN (Energy Efficiency by Switching between roles in WSNs) for the efficient use of energy in wireless sensor networks (WSN). Our solution ES-WSN extends the lifetime of the nodes in the network and guarantees a fair evolution of their level of energy.

Collaborative authentication in unattended WSNs
Proceedings of the second ACM conference on Wireless network security, 2009An unattended wireless sensor network (UWSN) might collect valuable data representing an attractive target for the adversary. Since a sink visits the network infrequently, unattended sensors cannot immediately off-load data to some safe external entity.

Erlang meets WSNs: A functional approach to WSN programming
2012 IEEE International Conference on Pervasive Computing and Communications Workshops, 2012The scarce diffusion of Wireless Sensor Network systems is due to several factors, among them the complexity in designing, programming and testing applications for this technology. Too often too specialized solutions have been proposed for specific scenarios, impeding code reuse and supporting poorly engineered development methodologies (i.e. “code and

Undervolting in WSNs: Theory and Practice
IEEE Internet of Things Journal, 2015Adapting the voltage level of a processing unit to the actual system load leads to an increased energy efficiency. The aim is to extend the battery lifetime, but existing voltage scaling approaches still act with reserve. To reduce the energy consumption even further, it is possible to power the electric circuits below the specified voltage levels ...

Integrable Autonomous Devices for WSNs
2017We here present an energy harvesting system for low power sensor applications. The system is a dual band architecture able to capture the largest amount of EM radiation available in the urban environment and to provide an autonomous device potentially with infinitive cycle of use.

Security in wireless sensor networks (WSNs) is centered on six fundamental requirements namely, authentication, confidentiality, integrity, reliability, availability and data freshness [4, 39, 52, 62]. In this chapter, we describe these requirements, the different kinds of attacks that aim to compromise these requirements (and hence the security of a ...
