Bluetooth Low Energy (BLE) and IEEE 802.15.4 Time-Slotted Channel Hopping (TSCH) are widely used low-power standard technologies developed for short-range communications in the internet-of-things. In many applications, BLE TSCH networks may be deployed vicinity of one another, which lead to Cross Technology Interference (CTI) influencing each other's performance. Both utilize channel hopping al...

Time Synchronized Channel Hopping (TSCH) is an existing medium access control scheme which enables robust communication through channel hopping and high data rates through synchronization. It is based on a time-slotted architecture, and its correct functioning depends on a schedule which is typically computed by a central node. This paper presents, to our knowledge, the first scheduling algorit...

In this study, tamarind (Tamarindus indica L.) seed extracts with potential antioxidant activity and toxicity to cancer cells were developed as functional foods and nutraceutical ingredients in the form of emulsion gel beads. Three extracts were obtained from ethanol and water: TSCH50, TSCH95 and TSCH. All extracts exhibited high potential for superoxide anion scavenging activity over the IC50 ...

In recent years, the adoption of industrial wireless sensor and actuator networks (IWSANs) has greatly increased. However, the time-critical performance of IWSANs is considerably affected by external sources of interference. In particular, when an IEEE 802.11 network is coexisting in the same environment, a significant drop in communication reliability is observed. This, in turn, represents one...

Time Slotted Channel Hopping (TSCH) is a medium access protocol defined in the IEEE 802.15.4 standard. It has proven to be one of most reliable options when it comes industrial applications. TSCH offers degree high flexibility and can tailored requirements specific Several performance aspects have been investigated so far, such as energy consumption, reliability, scalability many more. However,...

Emerging Industrial IoT applications, such as smart factories, require reliable communication and robustness against interference from co-located wireless systems. To address these challenges, frequency hopping spread spectrum (FHSS) has been used by different protocols, including IEEE802.15.4-2015 TSCH. FHSS can be improved with the aid of blacklists to avoid bad frequencies. The quality of ch...

Recent standardization efforts on low-power wireless communication technologies, including time-slotted channel hopping (TSCH) and DASH7 Alliance Mode (D7AM), are starting to change industrial sensing applications, enabling networks to scale up to thousands of nodes whilst achieving high reliability. Past technologies, such as ZigBee, rooted in IEEE 802.15.4, and ISO 18000-7, rooted in frame-sl...

The next percentile point of process optimization yields hundreds of billions of savings, and will be gained by leveraging the collection of currently unused measurements by widely distributed sensing devices and analytic capabilities. Gathering and processing this unused data will require the combination of the best of IT and OT technologies together, forming the IT/OT convergence, aka the Ind...
