Policy makers have implemented multiple non-pharmaceutical strategies to mitigate the COVID-19 worldwide crisis. Interventions had the aim of reducing close proximity interactions, which drive the spread of th...
Article
In animal ecology, inter-individual encounters are often investigated using automated proximity loggers. However, data acquired are typically spatially implicit, i.e. the question ‘Where did the contact occur?’ r...
Chapter and Conference Paper
Low-power wireless actuation is attracting interest in many domains, yet it is significantly less investigated than its sensing counterpart, especially in large-scale scenarios. As a consequence, guidelines ab...
Article
In modern distributed computing, applications are rarely built directly atop operating system facilities, e.g., sockets. Higher-level middleware abstractions and systems are often employed to simplify the program...

Chapter and Conference Paper
Wireless Sensor and Actuator Networks (WSNs) are distributed sensor and actuator networks that monitor and control real-world phenomena, enabling the integration of the physical with the virtual world. They ar...
Chapter and Conference Paper
We study the characteristics of the communication links of a wireless sensor network in a tropical cloud forest in Ecuador, in the context of a wildlife monitoring application. Thick vegetation and high humidi...
Chapter and Conference Paper
We target application domains where the behavior of animals or humans is monitored using wireless sensor network (WSN) devices. The code on these devices is updated frequently, as scientists acquire in-field d...
Chapter
Wireless networks define a very challenging scenario for the application programmer. Indeed, the fluidity inherent in the wireless media cannot be entirely masked at the communication layer: issues such as dis...
Chapter and Conference Paper
In their EWSN’07 paper [1], Giusti et al. proposed a decentralized wake-up scattering algorithm for temporally spreading the intervals in which the nodes of a wireless sensor network (WSN) are active, and showed ...
Chapter and Conference Paper
Wireless Sensor Networks (WSNs) are increasingly being proposed in scenarios whose requirements cannot be fully predicted, or where the system functionality must adapt to changing conditions. In these scenario...
Article
Next generation embedded systems will be composed of large numbers of heterogeneous devices. These will typically be resource-constrained (such as sensor motes), will use different operating systems, and will ...
Chapter and Conference Paper
Macroprogramming—the technique of specifying the behavior of the system, as opposed to the constituent nodes—provides application developers with high level abstractions that alleviate the programming burden in d...
Chapter and Conference Paper
Duty-cycling in wireless sensor networks (WSNs) has both beneficial effects on network lifetime and negative effects on application performance due to the inability of a sensor to perform while it is sleeping....
Chapter and Conference Paper
Initial deployments of wireless sensor networks (WSNs) were based on a many-to-one communication paradigm, where a single sink collects data from a number of data sources. Recently, however, scenarios with multip...
Chapter and Conference Paper
Wireless sensor networks (WSNs) are evolving to support sense-and-react applications, where actuators are physically interspersed with the sensors that trigger them. This solution maximizes localized interacti...
Chapter and Conference Paper
Wireless sensor networks (WSNs) typically exploit a single base station for collecting data and coordinating activities. However, decentralized architectures are rapidly emerging, as witnessed by wireless sens...
Chapter and Conference Paper
In this paper we describe a semi-probabilistic routing approach designed to enable content-based publish-subscribe on highly dynamic networks, e.g., mobile, peer-to-peer, or wireless sensor networks. We presen...
Chapter and Conference Paper
In this paper we introduce the concept of Distributed Abstract Data Type (dadt), a new programming model simplifying the development of distributed, context-aware applications. A dadt instance logically encapsula...
Chapter and Conference Paper
Mobile ad hoc networks (MANETs) define a challenging computing scenario where access to resources is restrained by connectivity among hosts. Replication offers an opportunity to increase data availability beyo...
