“…This makes it prone to a replay attack; thus, security should be provided by using timestamps for data. The network time distribution is highly dependent on the time stamp, which means that all factors that affect the time stamp have a direct impact on the final synchronization accuracy of the system [75].…”

As WSNs combine with a diversity of next-generation technologies, wireless sensor networks (WSNs) have gained considerable attention as a promising ubiquitous technology. Even though several studies on WSNs are being undertaken, few systematically analyze the security issues relating to them. Moreover, recent systems tend to be implemented without sufficient consideration about owns security requirements, which can lead to lethal threats. Systems that do not consider security requirements may provide attackers the opportunity to reduce the overall efficiency and performance of the system. This means that inadequately applied security requirements can result in defective security of systems. Therefore, in this study, we emphasized the importance of security requirements to raise awareness regarding them. In addition, we analyzed literature that could be improved by including WSNs security requirements such as characteristics, constraints, and threats. Furthermore, we adopted a systematic methodology by referring to reliable literature and performed a different analysis from previous studies. We derived and mapped the different security factors based on the literature and illustrated the relationships of each security factor. Finally, our research compared with studies of a similar type to evaluate whether it provided a significant contribution. In other words, in this study, we analyzed various factors related to WSNs security based on reviewing the literature and show our contribution, such as a systematic analysis framework and factor mapping compared with traditional studies. Though there are some considerations, we expect that this research derived the essential security requirements in any WSNs environments.

“…Another wireless synchronization scheme based on the interpolation of the cross-correlation peak but over IEEE 802.15.4 Chirp Spread Spectrum (CSS) is shown in [22], [23] and [24]. In [21] it is developed a theoretical analysis of the feasibility of the CSS modulation to perform precise timestamping and an early experimental validation is presented.…”

The Time-Sensitive networks paradigm envisions the integration of Operation Technology and Information Technology in the same network. One of the requirements for building Time-Sensitive networks is sharing a global time along the network. This requirement is especially critical in wireless systems, where there are few robust methods to perform accurate time transfer. In this paper, the problem of time transfer over realistic wireless channels is studied and a time distribution scheme is proposed. The time distribution scheme has three components: Precision Time Protocol, a novel timestamping method (enhanced timestamps) and an algorithm to implement the enhanced timestamps. The performance of the proposed scheme has been evaluated in MATLAB using the IEEE 802.11n standard under several standard Wireless Local Area Network channel models. The results show that the system can reach subnanosecond time transfer accuracy under Non-Line-of-Sight and time-variant conditions, but its performance greatly depends on the Signal-to-Noise-Ratio and on the channel variation rate.

“…In this case, quantization is not more the prevailing source of uncertainty. Experimental analyses (see, for instance, [23]- [25]) have shown that the timestamping noise is actually due to the contribution of several mechanisms. Under these assumptions v t (t) can be modeled by a zero-mean Gaussian process with variance σ 2 v,t .…”

The distribution of a time reference has long been a significant research topic in measurement and different solutions have been proposed over the years. In this context, the design of servo clocks plays an important role to get better performances by smoothing the influence of noise sources affecting a synchronization system. A servo clock is asked to provide an adaptive and conservative measure of the time distance between the local clock and the time reference by minimizing, if possible, the energy consumption. In this paper, we propose a servo clock based on an efficient implementation of the Kalman filter (KF), called in the following event-based KF that allows to overcome drawbacks of existing KF-based servo clocks with furthermore a significant reduction of the computational cost. An in-depth analysis of the synchronization uncertainty has been reported to completely characterize the proposed solution; and finally, some guidelines on how to correctly initialize the KF are provided.Index Terms-Clock modeling, event-based systems, Kalman filtering, synchronization, uncertainty analysis.
