“…The amount of nodes is different for each MCS and has been chosen to obtain a similar RTx period duration in every simulation. As it can be seen, the number of nodes supported by a Wireless SHARP network is considerable higher than other proposals based on 802.11g standard, such as IsoMAC [10] or [11], that could only support up to four nodes with the same control cycle.…”

“…However, IsoMAC is still far away from a communication cycle of 1 ms and cannot manage a high number of nodes [10]. Furthermore, we have found in previous works that 802.11g standard plus a TDMA MAC can be used to achieve 1 ms communication cycle [11]. However, the results show that it could only support up to 4 RT nodes with a Packet Error Rate (PER) of 10 -4 over a channel with 30 dB of Signal to Noise Ratio (SNR) and Rayleigh fading.…”

Industrial communications have very challenging requirements, especially in Factory Automation (FA) scenarios. Some of these requirements are: packet deadline bounds, high reliability, low transmission jitter, and communication determinism. Wireless communications solutions offer significant advantages over wired solutions: lower costs, faster and seamless deployment, higher flexibility and scalability, and free movement of the systems communicated wirelessly. However, standard wireless technologies do not provide enough performance to satisfy all of the industrial communications requirements in most cases and, therefore, wired solutions cannot be directly replaced by wireless solutions. In this work, we present SHARP (Synchronous and Hybrid Architecture for Real-time Performance in IWSAN), a novel hybrid architecture specially designed for industrial automation, where Ultra-Reliable Low-Latency Communications (URLLC) are required. This paper is mainly focused on the wireless segment of SHARP, a wireless architecture that includes a physical layer based on 802.11g along with a Time Division Multiple Access (TDMA) Medium Access Control (MAC) layer to ensure communication determinism, while maintaining backward compatibility with 802.11. Wireless SHARP segment behavior and its performance are evaluated through OMNeT++ simulations.

“…To control the shared wireless medium, an improved version of the TDMA-based MAC scheme defined in [45] is considered. This MAC protocol is defined in order to guarantee a deterministic and RT communication over wireless medium.…”

“…TSN technology has been chosen in contrast to other proprietary solutions such as EtherCAT. Moreover, TSN replaces the proprietary RTE solution proposed in [45]. TSN is a set of IEEE 802 sub-standards that aims to provide deterministic communication with RT guarantees over Ethernet by using time synchronization and scheduling information which is shared between all the devices of the network through TSN switches.…”

Wireless communications offer significant benefits over wired communications, which has increased their popularity in industrial applications. Nevertheless, the existing wireless standard technologies do not satisfy the requirements demanded by the most critical industrial applications and thus, wired communications cannot be directly replaced by wireless solutions. Moreover, the inclusion of movable nodes in the network brings new challenges, such as the handover mechanism. In this paper, a hybrid wired/wireless architecture designed for industrial control applications is proposed. To control the wired network, a timesensitive network (TSN) is used and to control the wireless network a medium access control (MAC) protocol is designed. In order to communicate both networks, a bridge that acts as a deterministic access point (AP) with real-time features is also proposed. One of the fundamental parts of the proposed architecture is that it can be used in applications with mobility requirements. Hence, a soft-handover algorithm is designed which guarantees uninterrupted communication during its execution without the need for a second radio interface and with reduced growth in network overhead. The proposed architecture is evaluated in order to assess its performance. This paper extends our previous work, including both a theoretical analysis to determine the delay bounds of the proposed architecture and a comparison between the performances of the proposed handover algorithm with other algorithms proposed in the literature. The evaluation has been carried out through OMNeT++ simulations. The results demonstrate the superiority of the proposed handover algorithm compared with other state-of-the-art solutions.
