High coupling efficiency 2D metasurface integrated with strip waveguide in SOI for mid-IR wavelengths
摘要： To avoid resources on green earth being exhausted much earlier by human beings, energy saving has been one of the key issues in our everyday lives. In fact, energy control for some appliances is an effective method to save energy at home, since it prevents users from consuming too much energy. Even though there are numerous commercial energy-effective products that are helpful in energy saving for particular appliances, it is still hard to find a comprehensive solution to effectively reduce appliances’ energy consumption in a house. Therefore, in this paper, an intelligent energy control scheme, named the residence energy control system (RECoS) is proposed, which is developed based on wireless smart socket and Internet of Things technology to minimize energy consumption of home appliances without deploying sensors. The RECoS provides four control modes, including peak-time control, energy-limit control, automatic control, and user control. The former two are operated for all smart sockets in a house, while the latter two are used by individual smart sockets, aiming to enhance the functionality of energy control. The experimental results show that the proposed scheme can save up to 43.4% of energy for some appliances in one weekday.

摘要： The Internet of Things (IoT) is becoming an attractive system paradigm to realize interconnections through the physical, cyber, and social spaces. During the interactions among the ubiquitous things, security issues become noteworthy, and it is significant to establish enhanced solutions for security protection. In this work, we focus on an existing U2IoT architecture (i.e., unit IoT and ubiquitous IoT), to design an aggregated-proof based hierarchical authentication scheme (APHA) for the layered networks. Concretely, 1) the aggregated-proofs are established for multiple targets to achieve backward and forward anonymous data transmission; 2) the directed path descriptors, homomorphism functions, and Chebyshev chaotic maps are jointly applied for mutual authentication; 3) different access authorities are assigned to achieve hierarchical access control. Meanwhile, the BAN logic formal analysis is performed to prove that the proposed APHA has no obvious security defects, and it is potentially available for the U2IoT architecture and other IoT applications.

A novel baseline-based method to detect local structural changes in masonry walls using dense terrestrial laser scanning point clouds
摘要： The ever-increasing advancement in communication technologies of modern smart objects brings with it a new era of application development for Internet of Things (IoT)-based networks. In particular, owing to the contactless-ness nature and ef?ciency of the data retrieval of mobile smart objects, such as wearable equipment or tailored bio-sensors, several innovative types of healthcare systems with body sensor networks (BSN) have been proposed. In this paper, we introduce a secure IoT-based healthcare system, which operates through the BSN architecture. To simultaneously achieve system ef?ciency and robustness of transmission within public IoT-based communication networks, we utilize robust crypto-primitives to construct two communication mechanisms for ensuring transmission con?dentiality and providing entity authentication among smart objects, the local processing unit and the backend BSN server. Moreover, we realize the implementation of the proposed healthcare system with the Raspberry PI platform to demonstrate the practicability and feasibility of the presented mechanisms.

摘要： To support the increased internet traffic, usage of 4G enabled smartphones and smart application of the Internet of Things (IoT) leads the requirement of spectrally scalable optical transport platform for the existing National Optical Fiber Network (NOFN) in India. Increasing traffic will soon exhaust the Conventional (C)-band. Therefore, we propose the novel architecture and the extension strategy enabling NOFN to consume the Long (L)-band and improve the total fiber capacity. Spectral expansion using L-band enables the twofold total fiber capacity and cost advantage over the already deployed fibers in the country. In this paper, we demonstrate the successful spectral expansion for NOFN enabling the C+L band transmission, two folding the total fiber capacity.

AR Enabled IoT for a Smart and Interactive Environment: A Survey and Future Directions
摘要： Accompanying the advent of wireless networking and the Internet of Things (IoT), traditional augmented reality (AR) systems to visualize virtual 3D models of the real world are evolving into smart and interactive AR related to the context of things for physical objects. We propose the integration of AR and IoT in a complementary way, making AR scalable to cover objects everywhere with an acceptable level of performance and interacting with IoT in a more intuitive manner. We identify three key components for realizing such a synergistic integration: (1) distributed and object-centric data management (including for AR services); (2) IoT object-guided tracking; (3) seamless interaction and content interoperability. We survey the current state of these respective areas and herein discuss research on issues about realizing a future smart and interactive living environment.

Integrated Light Sensing and Communication for LED Lighting
摘要： Solid state lighting is nowadays widely diffused both in residential and of?ce or industrial environment. Ambient light sensing to modulate lamp power is typical too, but sensors inside a lamp are a challenge, due to the high ?ux of these sources, which easily saturates nearby light detectors. Usually, separate sensing devices must be introduced in the system, thus increasing complexity and cost. In this work, a methodology will be presented, to allow integration of a light sensing device inside a lamp, using low cost circuitry to mitigate interactions between high power light-emitting diode (LED) sources and sensing photodiodes. Moreover, the same circuit allows visual light communication among sources.

Segregation-free bromine-doped perovskite solar cells for IoT applications
摘要： Perovskite solar cells have attracted much attention as next-generation solar cells because of their high e?ciency and low fabrication costs. Moreover, perovskite solar cells are a promising candidate for indoor energy harvesting. We investigated the e?ect of bandgap tuning on the characteristics of triple cation-based perovskite solar cells under ?uorescent lamp illumination. According to the current density–voltage curves, perovskite solar cells with a wider bandgap than the conventional one exhibited improved open-circuit voltage without sacri?cing short-circuit current density under ?uorescent lamp illumination. Moreover, the wider bandgap perovskite ?lms including a large amount of bromine in the composition did not show phase segregation, which can degrade the photovoltaic performance of perovskite solar cells, after ?uorescent lamp illumination. Our results demonstrate the facile strategy to improve the performance of perovskite solar cells under ambient lighting and great potential of perovskite solar cells for indoor applications such as power sources for the internet of things.

[IEEE 2019 AEIT International Annual Conference (AEIT) - Florence, Italy (2019.9.18-2019.9.20)] 2019 AEIT International Annual Conference (AEIT) - Multi-Layer RNN-based Short-term Photovoltaic Power Forecasting using IoT Dataset
摘要： Photovoltaic power ?uctuation in daytime is one of critical problems for the ef?cient and stable operation of the smart grid. To respond the PV power ?uctuation resulting from weather change, the short-term PV power forecasting algorithm using multi-layer RNN is proposed in this paper. It consists of multiple RNN layers using power and meteorological data which are collected by on-site IoT (Internet of Things) sensors. Experimental results showed that the accuracies of the short-term PV power prediction of 5 minutes and 1 hour later using 3 RNN layers with 12 time-step were 98.02% and 96.58% based on the normalized RMSE, respectively. These experimental results con?rmed that the proposed short-term prediction algorithm using multi-layer RNN model was applicable to respond the short-term PV power ?uctuation.
