This chapter reviews time synchronization and calibration for wireless sensor networks.
Authors show that time synchronization can be considered as a calibration problem and …

What started with the sundial has, thus far, been refined to a level of precision based on
atomic resonance: Time. Our obsession with time is evident in this continued scaling down …

Within the wide range of issues related to 4G wireless networks, due to the scope of the
ISSTA conference, in this presentation we highlight some segments of wireless networks …

In this paper, we present a novel control-theoretic time synchronization algorithm, named
PISync for synchronizing sensor nodes in wireless sensor networks (WSNs). The PISync …

Wireless sensor networks consist of many nodes that collect real-world data, process them,
and transmit the data by radio. Wireless sensor networks represent a new, rapidly …

Researchers have proposed many wireless MAC protocols such as [20],[8],[25],[24],[6], and
[17] which exploit frequency-agile radios and multiple available channels to increase …

This paper proposes another direction to implement a lightweight synchronization service for
wireless sensor nodes. To this end, we present gradient descent synchronization (GraDeS) …

This paper presents PISync, a novel distributed synchronization algorithm based upon a
Proportional-Integral (PI) controller for Wireless Sensor Networks (WSNs). PISync …

Accuracy is one of the most important performance metrics in clock synchronization. While
state-of-the-art synchronization protocols achieve μ sec-order average accuracy, they …

The status quo for time stamping in personal computers (PCs) is ntpd, which, under general
conditions, is accurate to 1 ms at best. For precision applications, it is inadequate, but it is a …
