Clock synchronization is a prerequisite for the realization of emerging applications in various
domains such as industrial automation and the intelligent power grid. This paper surveys the …

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 …

The accurate and efficient operation of many applications and protocols in wireless sensor
networks require synchronized notion of time. To achieve network-wide time …

In this paper, we propose a novel clock calibration approach called FLIGHT, which
leverages the fact that the fluorescent light intensity changes with a stable period that equals …

Time synchronization is a fundamental problem in any distributed system. In particular,
wireless sensor networks (WSNs) require scalable time synchronization for implementing …

Synchronization to an external time source such as Coordinated Universal Time (UTC), ie,
external synchronization, while preserving tight synchronization among neighboring sensor …

In this paper, we introduce Pulsar, a wireless time transfer platform that can achieve clock
synchronization to better than five nanosecond between indoor or GPS-denied devices …

A desirable flooding-based time synchronization protocol in Wireless Sensor Networks
(WSNs) should neither demand fast propagation of up-to-date time information nor keeping …

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

We present insights obtained from conducting a year-long, 455 meter deployment of
wireless plug-load electric meters in a large commercial building. We develop a stratified …
