The Low Latency Deterministic Network (LLDN) protocol is defined in the IEEE 802.15.4e, which is an amendment to the IEEE 802.15.4 standard specifically devised to support the requirements of industrial applications. The LLDN provides a TDMA-based medium access mechanism in which the network cycle time grows linearly with the number of nodes. As a result,(More)
This paper proposes a Lightweight version of the Precision Time Protocol, called L-PTP, for implementation on Powerline communication systems. The aim of this novel protocol is to reduce the number of messages exchanged to achieve synchronization, without penalizing its quality. L-PTP introduces several modifications to the original PTP and can be(More)
The IEEE 802.1 Audio/Video Bridging (AVB) protocol successfully supports audio/video streaming over Ethernet networks and is also a promising candidate for industrial automation. However, several industrial automation applications feature requirements that cannot be fulfilled by the current AVB standard. The next generation of IEEE 802.1 standards, which(More)
—The PRIME (PoweRline Intelligent Metering Evolution) protocol is a very popular multicarrier narrowband PLC protocol that fits the needs of advanced metering infrastructure applications. This paper proposes a performance assessment of the PRIME MAC layer protocol obtained through OMNeT simulations in different scenarios. The contribution of the paper is(More)
Communication networks for cooperative mobile robot applications have to cope with some peculiar requirements that make them quite different from typical MANETs or WSNs. Recent cooperative robot applications envisage the support of low datarate communication technologies, as this choice is beneficial in terms of energy consumption, weight reduction and(More)
The spread use of IEEE 802.11 networks in industrial automation raised the need to support multiple traffic classes with different requirements. This paper proposes a novel approach, called SchedWiFi, that provides flexible support to the scheduled traffic class, i.e., a high priority traffic class that is transmitted according to a fixed schedule, over(More)
—Real-Time Ethernet (RTE) technologies are becoming increasingly popular, as they provide high bandwidth and are able to meet the requirements of industrial real-time communications. Among RTE protocols, the EtherCAT standard is suitable for motion control and closed-loop control applications, which require very short cycle times. As EtherCAT was(More)
