Internet of Things (IoT) is expected to change the everyday life of its users by enabling data
exchanges among pervasive things through the Internet. Such a broad aim, however, puts …

Considering its central importance to sensor networks, time synchronization has received
extensive attention by the research community. Nevertheless, we argue in this paper that …

A sensor-based community network for environmental data gathering and predictive
analysis has been developed. A mesh network of wireless sensors reports data to a central …

Collecting highly accurate scientific measurements asks for highest data quality and yield.
But, satisfying these requirements is non-trivial, when considering phenomena common to …

We present the design of the Tempo mote that operates on ambient energy harvested from
the environment. Equipped with a ultra low-power timing module that acquires Coordinated …

We discuss the history and lessons learned from a series of deployments of environmental
sensors measuring soil parameters and CO2 fluxes over the last fifteen years, in an outdoor …

Over the last few years the rise of cloud, mobile and social technologies has driven the
influence of the Web into traditional value chains, digitizing many transactional and social …

Time synchronization is an essential service in many sensor network applications. Harsh
environment which causes nodes to fail, go offline, or reboot can challenge many time …

The notion of global time is of great importance for many sensor network applications. Time
reconstruction methods aim to reconstruct the global time with respect to a reference clock …

Environmental scientists frequently engage in” campaign-style” deployments, where they
visit a location for a relatively short period of time (several weeks to months) and intensively …
