“…All these MAC protocols (including but not limited to [13]- [19]) involves the CSMA/CA mechanism being more valuable to protect ordinary wireless sensor networks from packet collisions rather than time-critical Wireless Sensor and Actuator Networks (WSAN) with hard requirements for deterministic delay guarantees. HyMAC [20] is a class of MAC protocols merging TDMA and FDMA together. Although HyMAC guarantees a certain end-to-end delay, the main drawback is the lack of ability to adapt to the harsh wireless channel conditions of industrial automation or avionics.…”

Abstract-Wireless sensor networks are typically designed for condition monitoring applications and to conserve energy but not for time-critical applications with strict real-time constraints that can be found in the industrial automation and avionics domain. In this paper, we propose a novel medium access control (MAC) protocol defined as wireless arbitration (WirArb) which grants each user channel access based on their different priority levels. The proposed MAC protocol supports multiple users and each user is pre-assigned a specific arbitration frequency which decides the order of channel access. With this mechanism, we can ensure that the user with the highest priority will immediately gain channel access and we can guarantee a deterministic behavior. To evaluate the proposed MAC, we use a discrete-time Markov chain model to mathematically formulate the WirArb protocol. Our results show that the proposed protocol provides high performance to ensure deterministic real-time communication and bandwidth efficiency.

“…Salajegheh et al, [12] focused on Hybrid MAC protocol, to provide high throughput and small bounded end-to-end delay for the packets exchanged between each node and the sink. HyMAC is a combination of TDMA and FDMA protocols in which data gathered by sensor nodes has to be delivered to at least one sink node in a timely manner.…”

Abstract-Multi-Channel Dynamic Scheduling has been centric stage of research in WSNs in recent years. In this paper, we propose a Distributed Multi-Channel Scheduling MAC communication protocol (DMS-MAC) to improve the network performance of WSNs, which selects the best channel for an individual wireless sensor node. DMS-MAC supports dynamic channel assignment mechanism where each sensor node is equipped with a directional antennas. The proposed protocol helps to decrease the probability of collision, interferences and improves the overall network performance of Wireless Sensor Networks (WSNs). The protocol is most suitable for short packet transmission under low traffic networks and has ability to utilize parallel transmission among neighboring nodes and achieves increased energy efficiency when multi-channels are available. Simulation result shows that the proposed protocol improves the performance of aggregate throughput, probability of successful transmission, packet delivery ratio, energy consumption and average end-to-end delay.

“…They assume that the sink is equipped with multiple transceivers, which can operate at different channels selected adaptively, while the other nodes use one transceiver. Furthermore, HyMAC [47] is designed for a network in which the nodes are equipped with multiple-channel transceivers, i.e., a different channel can be selected in each transmission. In this protocol, the combination of TDMA and FDMA features are exploited.…”

While traditional wired communication technologies have played a crucial role in industrial monitoring and control networks over the past few decades, they are increasingly proving to be inadequate to meet the highly dynamic and stringent demands of today's industrial applications, primarily due to the very rigid nature of wired infrastructures. Wireless technology, however, through its increased pervasiveness, has the potential to revolutionize the industry, not only by mitigating the problems faced by wired solutions, but also by introducing a completely new class of applications. While present day wireless technologies made some preliminary inroads in the monitoring domain, they still have severe limitations especially when real-time, reliable distributed control operations are concerned. This article provides the reader with an overview of existing wireless technologies commonly used in the monitoring and control industry. It highlights the pros and cons of each technology and assesses the degree to which each technology is able to meet the stringent demands of industrial monitoring and control networks. Additionally, it summarizes mechanisms proposed by academia, especially serving critical applications by addressing the real-time and reliability requirements of industrial process automation. The article also describes certain key research problems from the physical layer communication for sensor networks and the wireless networking perspective that have yet to be addressed to allow the successful use of wireless technologies in industrial monitoring and control networks.
