“…Another feature in the IEEE 802.15.4e standard is the frequency hopping, which could improve the reliability of the data transmission [24]. Since the IEEE 802.15.4e TSCH standard does not specify how to plan the time slot scheduling, Wang et al [25] proposed a distributed scheduling strategy such that each sensor node knows the time to transmit packets in a distributed and simple manner.…”

The indoor inventory system is gaining more research attention and commercial value with the development of IoT. In this thesis, we presented the design of a MAC protocol that allows synchronized transmission of location and sensing data in a wireless positioning and sensor network for an indoor inventory system. The network supports real-life industrial applications and provides a highly specific positioning method.<div>In the network, mobile sensing tags are connected to smart readers that performs localization of tags and gathers sensing data from the tags. The readers are connected to the back-end cloud. The proposed MAC serves multiple classes of mobile tags with different priorities and latency requirements. These tags transmit critical, position and sensing data with different QoS requirements. The proposed MAC is a hybrid MAC that offers contention-based period for tag discovery and scheduled period for the transmission of sensing data with guaranteed latency. We conducted simulation to evaluate the performance of different methods of discovery process and their impact on latency assurance. We also developed a queuing model to analyze the relationship between parameters, acquiring parameters through experiment, and calculation of boundary values.<br></div><div>Simulation using MatLabTM software suggests that the joining period in design can increase the transmission success rate of high priority messages at the cost of a slight increment in the delay of low priority messages. Preliminary analysis suggests that by adaptively allocating the channel resources of the network to three types of tags, service efficiency can be improved. This result also guides the direction for further improvement.<br></div><div>We explored the performance of two options considered currently, which is selecting the discovery process according to modulo result of unique 16-bit tag ID and random select of an available discovery process. In the current environment where each tag does not have any information about other tags inside the network, the two methods have the same effect on avoiding collisions that could happen in a single discovery cycle.<br></div><div>The proposed MAC layer protocol can provide the best service when the available discovery process in the discovery cycle is for initialization and resetting. For an emergency, the joining period designs can still ensure a success rate for critical messages to be over 90%. Hence, the simulation results indicate the joining period method is able to improve MAC-layer performance.</div><div> <br></div>

“…In distributed approaches, neighbouring nodes negotiate with each other and decide locally on which links to schedule their own plan for wake up and sleep time. In this class, many works were proposed by Accettura et al (2013Accettura et al ( , 2015, Aijaz and Raza (2017), Demir andBilgili (2017), Domingo-Prieto et al (2016), Antoni et al (2013), Tinka et al (2010), Soua et al (2015aSoua et al ( , 2015b and Wang and Hwang (2015). Indeed, these solutions have a quick response to the sudden changes of network topology, but still need an additive communication overhead for the negotiation between neighbours.…”

Using the internet of things technologies in manufacturing provides a promising opportunity to build powerful industrial systems and applications. The quest for mobility, flexibility, and low-energy consumption has created a strong push toward using low-power wireless solutions to enable the industrial internet of things (IIoT). This paper presents a survey of the emerging research concerning IIoT with a focus on the most promising solutions. It, first, outlines the main requirements to be addressed in order to build a powerful IIoT system. The paper, then, presents an overview accompanied by a comparative study of the most prevalent IIoT communication technologies. The study reveals the potential of the IEEE 802.15.4 standard with its time slotted channel hopping (TSCH) mode to lead the way through the IIoT, thanks to its latency, reliability and low-power characteristics along with the support of multi-hop communications. Based on this outcome, the paper provides an in-depth look at TSCH mechanisms and outlines the most challenging issues. Finally, the paper concludes the need to propose new solutions addressing such issues in order to make successful IIoT systems.

“…Saifulah et al [17] aim at channel scheduling with deadline in Wireless HART networks, where the wireless links are assumed to be highly reliable. Wang et al [15] propose a decentralized scheduling algorithm to allocate the channels and time slots in order to jointly reduce control overhead, packet transmission delay and duty cycle. In these works, the underlying assumption is that a packet transmission is successful in one slot and the corresponding channel.…”

Body Sensor Network (BSN) is a typical Internet-of-Things (IoT) application for personalized health care. It consists of economically powered, wireless and implanted medical monitoring sensor nodes, which are designed to continually collect the medical information of the target patients. Multichannel is often used in BSNs to reduce the spectrum competition of the tremendous sensor nodes and the problem of channel assignment has attracted much research attention. The health sensing data in BSNs is often required to be delivered to a sink node (or server) before a certain deadline for real time monitoring or health emergency alarm. Therefore, deadline is of significant importance for multichannel allocation and scheduling. The existing works, though designed to meet the deadline, often overlook the impact of the unreliable wireless links. As a result, the health sensing data can still be overdue because of the scheduled lossy links. Besides, potential collisions in the schedules also incur considerable delay in delivering the sensing data. In this paper, we propose a novel deadlinedriven Link quality Aware Channel Assignment scheme (LACA), where link quality, deadlines and collisions are jointly considered. LACA prioritizes links with urgent deadlines and heavy collisions. Besides, LACA allows the exploition of the spare slots for retransmissions on lossy links, which can further reduce the retransmission delay. Extensive simulation experiments show that compared to the existing approaches, LACA can better utilize the wireless spectrum and achieve higher packet delivery ratio before the deadline.
