[IEEE 2018 IEEE 4th International Forum on Research and Technology for Society and Industry (RTSI) - Palermo, Italy (2018.9.10-2018.9.13)] 2018 IEEE 4th International Forum on Research and Technology for Society and Industry (RTSI) - Internet of Things for Environmental Monitoring Based on Radio Over Fiber
摘要： Radio over Fiber (RoF) is one of the main technologies for the next-generation access networks due to its immunity to electromagnetic interference, low latency, low power consumption and high transmission capacity. RoF enables the processing of several radio frequency (RF) signals in a centralized location, reducing both capital expenditures (CAPEX) and operating expenditures (OPEX). This paper describes a testbed of Internet-of-Things (IoT) for environmental monitoring based on RoF that is under development in the framework of the H2020 FUTEBOL project. Moreover, we assess the impact of RoF on network performance by using a new methodology oriented to real environments.

A Novel Industrial Safety IoTs Architecture for External Corrosion Perception Based on Infrared
摘要： In this paper, a novel external corrosion risk online perception method is proposed to solve the dangerous external corrosion threat and supply a measurable safe risk perception ability for the industrial safe Internet of Things (IoTs) with the infrared thermal wave as the direct sensors. The three layers model is established with direct variables measuring layer, external corrosion risk soft measuring layer and monitoring cycle decision-making layer. And in the direct variable measuring layer the infrared thermal wave is applied to measure the three direct variables, area ratio of cladding defects,cladding layer thickness reading and overlapping between external and internal corrosion defects, in the direct variables measuring layer. In the external corrosion risk soft measuring layer and monitoring cycle decision-making layer, external corrosion risk can be soft measured through a cladding-condition-based risk matrix and the most optimal monitoring cycle can also be determined through a decision-making tree based on the three direct variables.

[IEEE 2018 IEEE 7th Global Conference on Consumer Electronics (GCCE) - Nara, Japan (2018.10.9-2018.10.12)] 2018 IEEE 7th Global Conference on Consumer Electronics (GCCE) - Motion Tolerance for Dynamic Object Recognition Using Visible Light IDs
摘要： Dynamic recognition of objects labeled by visible light IDs is numerically investigated for obtaining a high optical signal-to-noise ratio in received optical signals when a relative motion between the objects and observer considerably alters. An averaging effect of pixel values in an image sensor shows a trade-off between reductions in accumulated image sensor noises and spatially varying noises originating from the relative motion. Our results suggest that a real-time optimization of the averaging process is suitable for an efficient recognition of visible light IDs toward applications for the disaster risk reduction.

[Institution of Engineering and Technology 12th European Conference on Antennas and Propagation (EuCAP 2018) - London, UK (9-13 April 2018)] 12th European Conference on Antennas and Propagation (EuCAP 2018) - Embedded Antenna Design on LoRa Radio for IoT Applications
摘要： This paper presents a miniaturized printed inverted-F antenna (PIFA) embedded on the circuit board of a LoRa sensor node for the internet of things (IoT) applications. On the 1.6 mm-thick board, very limited space is reserved for the antenna deployment, and therefore slots are cut on the ground to reduce operating frequency of the PIFA and create another resonance to broaden the bandwidth. Finally, the proposed antenna is optimized to operate from 402.4 MHz to 441.6 MHz with voltage standing wave ratio (VSWR) less than 3, and its realized gain over the 410-441 MHz LoRa frequency band is higher than -6 dBi.
