“…The default setup of the simulation (unless changed for a specific metric comparison) considers a packet payload length of 1 byte, a varying data rate of 0.01 to 3 s per packet created and a channel bitrate of 250 k bits per second. The chosen data rate values are intended to cover a wide range of different application scenarios, from intensive high-data rate applications such as real-time structural health monitoring [40] or aircraft active flow control [41] to much more relaxed environmental monitoring scenarios. In terms of the protocol standard constants, the beacon order was set to 6, multisuperframe order was 5 and the superframe order was 4.…”

The fast development and adoption of IoT technologies has been enabling their application into increasingly sensitive domains, such as Medical and Industrial IoT, in which safety and cyber-security are paramount. While the number of deployed IoT devices increases annually, they still present severe cyber-security vulnerabilities, becoming potential targets and entry points for further attacks. As these nodes become compromised, attackers aim to set up stealthy communication behaviours, to exfiltrate data or to orchestrate nodes in a cloaked fashion, and network timing covert channels are increasingly being used with such malicious intents. The IEEE 802.15.4 is one of the most pervasive protocols in IoT and a fundamental part of many communication infrastructures. Despite this fact, the possibility of setting up such covert communication techniques on this medium has received very little attention. We aim to analyse the performance and feasibility of such covert-channel implementations upon the IEEE 802.15.4 protocol, particularly upon the DSME behaviour, one of the most promising for large-scale time critical communications. This enables us to better understand the involved risk of such threats and help support the development of active cyber-security mechanisms to mitigate these threats, which, for now, we provide in the form of practical network setup recommendations.

“…However, there is still a lack of ready-to-use and off-the-shelf WSN technologies able to fulfil the most demanding requirements of SHM applications, such as stringent time synchronization of all sensors’ measurements, highly reliable timely measurements and data communications. In this line, we designed a prototype system for SHM ((Severino et al 2010) and (Aguilar et al 2011)), capable of coping with these SHM requirements while supporting network scalability.…”

While Cluster-Tree network topologies look promising for WSN applications with timeliness and energy-efficiency requirements, we are yet to witness its adoption in commercial and academic solutions. One of the arguments that hinder the use of these topologies concerns the lack of flexibility in adapting to changes in the network, such as in traffic flows.This paper presents a solution to enable these networks with the ability to self-adapt their clusters’ duty-cycle and scheduling, to provide increased quality of service to multiple traffic flows. Importantly, our approach enables a network to change its cluster scheduling without requiring long inaccessibility times or the re-association of the nodes. We show how to apply our methodology to the case of IEEE 802.15.4/ZigBee cluster-tree WSNs without significant changes to the protocol. Finally, we analyze and demonstrate the validity of our methodology through a comprehensive simulation and experimental validation using commercially available technology on a Structural Health Monitoring application scenario.
