Distributed architectures for industrial applications are a new opportunity to realize cost-effective, flexible, scalable and reliable systems. Direct interfacing of sensors and actuators to the industrial communication network improves the system performance, because process data and diagnostics can be simultaneously available to many systems and also(More)
—This paper deals with a smart-transducer wireless network for industrial applications. Thanks to its high popularity, a solution based on IEEE802.11 (also known as wireless fidelity or Wi-Fi) is experimentally investigated. A master–slave network organization is proposed to allow several sensors to be connected with generic Wi-Fi devices like PCs; a(More)
This paper deals with the problem of coexistence of wireless sensor networks (WSNs) for industrial applications, proposing new approaches. In fact, if several WSNs operate in the same area, the reliability of the system rapidly decreases, especially if static radio channel assignment WSNs and frequency hopping WSNs are mixed. The proposed architecture is(More)
Ethernet technology is widely used in real-time industrial automation. Thanks to real-time Ethernet (RTE) protocols, defined in IEC61784-2 standard, new top-performance automation solutions can be created. Such systems may have communication cycle time down to tens of mus and cycle jitter less than 1 mus, making network testing and debugging very critical.(More)
—In this paper, a Bluetooth-based sensor network is presented. Based on a Piconet, the proposed network supports Web-server capabilities, allowing the wireless sensors to be accessed by commercial browsers through the Internet. An experimental setup has been realized using three temperature sensors, and related information has been viewed by PC clients.(More)
