“…It is possible to have simultaneous transmissions in the same time-slot, in which each transmitter transmits to a different receiver, and using a different channel. When a pair of time-slot and channel is dedicated to only one node, the communication medium can be accessed directly inside the time-slot, without contention, otherwise the nodes use a modified CSMA/CA algorithm to access the channel, to reduce collisions [6]. The slot-frame automatically repeats, and all nodes have a shared notion of time.…”

“…Recently, the IEEE 802.15.4e standard was released, with the goal of proposing solutions for applications that require high reliability, such as industrial applications [6]. Five modes of operation are defined, that is: Time-Slotted Channel Hopping (TSCH), Deterministic and Synchronous Multi-Channel Extension (DSME), Low Latency Deterministic Network (LLDN), Asynchronous Multi-Channel Adaptation (AMCA), and Radio Frequency Identification Blink (BLINK).…”

“…Some solutions use multiple channels simultaneously, with multiple transceivers in the sensor nodes, or using different channels in different segments of the network [4]. Other approaches use frequency hopping, such as Medium Access Control (MAC) protocols of WirelessHART, ISA100.11a, and IEEE 802.15.4e standards [5] [6]. Some works focus on dynamic channel allocation mechanisms [7] [ 8], in which the WSN changes the channel when its quality decreases.…”

Abstract-The use of Wireless Sensor Networks (WSN) in industrial environments is subject to problems, such as shadowing and fading. In addition, the wireless channel in many industrial environments is non-stationary for a long term, which can cause abrupt changes in the characteristics of the channel over time. A way to deal with those problems is the use of multi-channel protocols. However, it is difficult to evaluate, and compare different approaches because there is no reliable simulation model for industrial environments. This paper presents experimental results that characterize the wireless channel in industrial environments, and proposes a simulation model that captures the effects of fading, shadowing, and the non-stationary characteristics of the channel. It also considers the differences in the behavior of the different channels, and the asymmetry of the links. The model was integrated into the open source simulator Castalia. After the integration, two simulation studies were performed with the proposed model. In the first one, the Tree-based Multi-Channel Protocol was implemented and evaluated, and a comparison was made with the default model from Castalia. In the second case, CSMA/CA protocol, as defined in IEEE 802.15.4 standard, was compared to a protocol based on Time-Slotted Channel Hopping (TSCH) mode of IEEE 802.15.4e standard. The results showed that the use of TDMA and channel hopping is an alternative to deal with the problems of wireless channels in industrial environments.

Abstract-Time-Slotted Channel hopping (TSCH) that was introduced in IEEE802.15.4e is a promising technique to offer deterministic data deliveries in Wireless Sensor Networks (WSN). Its main strength lies in using multiple channels for the transmissions, using frequency hopping method. However, it takes more time for initializing the network, as beacons have to be released on multiple frequencies and scanning needs to be carried out by the devices in all those frequencies for joining the network. In this work, a simulation study is carried out to investigate the effect of these delays for different types of multihop networks. The benefit of introducing multiple coordinators in reducing these time delays is also studied. It is found that the delays are increasing linearly with the number of hops in the network and adding an additional coordinator can bring down the initialization time by half.

With the development of technology for the Internet of Things (IoT), a large number of mobile, intelligent sensors are being connected to the Internet. The IoT is a heterogeneous environment. In industrial environments, wireless technologies coexist on the same frequency and generate different kinds of traffic. The use of different wireless technologies that are not designed to be compatible with each other causes an external interference problem, which degrades the system performance. The medium access control (MAC) sublayer protocols must be carefully designed to overcome such a problem. The time‐slotted channel‐hopping (TSCH) mode, which is dedicated for industrial applications, can mitigate such a problem because it uses the channel‐hopping technique. Because these channels are subjected to different levels of interference, this may greatly degrade the system performance when wireless sensors with mobility devices hop blindly from one channel to another. This paper improves the reliability of communications of the TSCH MAC sublayer protocol, proposed by the IEEE 802.15.4e standard, in wireless sensor networks, by applying a new, dynamic blacklisting technique. The technique selects and uses only high‐quality channels and blacklists those with low quality. The proposed solution has been simulated using Network Simulator 3. The results show significant improvements in terms of throughput, energy, and reliability.
