The recent advances in the Internet of Things (IoT) area, which has provided an increasing availability of networked sensors and actuators, has given a new perspective to research in the sensor data processing in IoT. In this sense, the main contribution of this paper is the proposition of COIOT(COntext + IOT), an architecture proposal for distributed sensing in IoT designed with the aim of providing, through rules, the proactive management of the EXEHDA Middleware interactions with the physical environment. To evaluate the functionalities of the proposed architecture we implemented a case study in the agricultural area. The achieved results are very promising.

In this paper is presented a new printed monopole antenna, bio-inspired by jasmine flower, that meets the Federal Communications Commission parameters for ultra-wideband systems. The design of the printed monopole antenna in jasmine flower has developed from a printed monopole antenna with circular geometry, with comparison results. The measured results of bio-inspired antenna in the jasmine flower showed compatibility with the parameters required by the FCC for ultra-wideband technology. It obtained bandwidth of 9.75 GHz, half-power beamwidth of 148 degrees, omnidirectional radiation pattern, gain of 5.99 dBi, power spectral density below -41.3 dBm across the bandwidth of ultra-wideband technology, small pulse distortion, and constant group delay, with variations of less than 2ns.

Modern instrumentation systems must typically deal with challenges such as remote access, device heterogeneity and automated configuration. IoT infrastructures can be useful in this scenario because the technologies used in IoT environments can also be used to cope with the cited difficulties. In this paper, we present a remote measurement instrument whose design prioritizes integration with an ubiquitous computing middleware, exploring the convergence between instrumentation and IoT. In particular, the instrument, which is called ubiMeter, uses the context awareness features of the EXEHDA middleware. Its capabilities were evaluated in two different case studies, which yielded promising results.

Beamforming front-ends are an attractive technology because it concentrates its radiated power in one direction, which can improve energy efficiency and reduce undesirable interference. In this context, electronic beamforming systems have lower cost than mechanical ones. Knowing the uses of directive antennas and power dividers in electronic beamforming systems, this work aims at the design, simulation and measurements of these components at 5.8 GHz. Measurements with Power Divider showed very good return and insertion losses at 5.8 GHz: S11 = -23.5 dB and S21 = -3.8 dB. A printed dipole antenna was then fabricated, presenting -14.6 dB of return losses and a 2.82 dBi gain. Later, a 2-antenna beamforming front-end was implemented, proving the beamforming capability with the proposed devices. It also presented S11 = -15.7 dB, and a high directive gain (10.3 dBi). Since this is still a preliminary work, the results presented are very promising.

The use of impedance spectroscopy makes it possible to identify different substances based on their different fingerprint. In industrial applications, impedance spectroscopy has the potential to monitor processes. It is a technique of simple implementation, low cost and minimally invasive. In this study, a system based on electrical impedance spectroscopy was developed, calibrated and validated. The system comprises a sensing cell, an electronics and data processing algorithms for data extraction. The system was implemented and evaluated by measuring known substances, showing promising first results. As an example of application, the ice formation process under controlled conditions was monitored. The results show the capability of the developed system to monitor processes via impedance spectroscopy.

Microelectrode arrays have extensive applications in the biomedical field. These applications range from the study of the influence of drugs in cell cultures to neuro-implants for attenuation of diseases, such as Parkinson's disease and epilepsy. The main block of the analog front-end attached to the MEA is the bioamplifier that amplifies biomedical potential signals. Different designs for this block are presented in literature and a comparison between them is needed to analyze the best performance possible when working with MEA systems. This review paper presents an overview on MEA systems, focusing on the bioamplifier and its components with the goal of providing a design suggestion that maximizes the performance of MEA signal acquisition.

The more technology advances, more connected and participative citizens are shaped, creating an environment driven by surroundings context knowledge and aiding in critical decisions as answer to perceived occurrences. This work describes an automated DAS communicating to an instance of 52°North SOS, an implementation of OGC SWE specification, that enables interaction and interoperability of sensors on the web. DAS architecture is divided into four layers. Main component is an Arduino Nano. Results showed that IoT and SWE combined with this approach improves effectiveness of observation processes and decision-making. Arduino Nano limitation provokes instabilities with Ethernet module if memory is massively used, but default source options grants four samples every hour, and a five observations queue in case of connection fault. Ethernet module thermal influence demands subtraction of 2 °C from sensed temperature to achieve its real data. This paper introduces an approach to build a low cost automated DAS to obtain local scale data of urban sites temperature and humidity based in IoT applying a whole infrastructure since sensing to data visualization as a new implementation for local scale meteorology in the actual context of big data and IoT.

The industrial, scientific and medical band is widely used by different wireless systems. The identification of other wireless technologies in the common environment is one of the keys for correct system coexistence. In this work, a sensing platform for the detection of IEEE 802.11g and IEEE 802.15.4 primary signals in the 2.4 GHz band is proposed. The sensing platform makes use of a combined scheme between energy detection and cyclostationarity-based methods for better accuracy. A universal software radio peripheral equipment is used for the acquisition of RF signals. Meanwhile, the signal processing and detection methods are performed in software domain by means of LabVIEW. Experimental testes are developed for evaluating the proposed platform and algorithms. The reliability rate and correct classification of the signals are the chosen parameters for evaluation of the proposal. The results show the optimal threshold for achieving an adequate reliability rate.
