A Plug-and-Play Human-Centered Virtual TEDS Architecture for the Web of Things

Abstract

This article presents a Virtual Transducer Electronic Data Sheet (VTEDS)-based framework for the development of intelligent sensor nodes with plug-and-play capabilities in order to contribute to the evolution of the Internet of Things (IoT) toward the Web of Things (WoT). It makes use of new lightweight protocols that allow sensors to self-describe, auto-calibrate, and auto-register. Such protocols enable the development of novel IoT solutions while guaranteeing low latency, low power consumption, and the required Quality of Service (QoS). Thanks to the developed human-centered tools, it is possible to configure and modify dynamically IoT device firmware, managing the active transducers and their communication protocols in an easy and intuitive way, without requiring any prior programming knowledge. In order to evaluate the performance of the system, it was tested when using Bluetooth Low Energy (BLE) and Ethernet-based smart sensors in different scenarios. Specifically, user experience was quantified empirically (i.e., how fast the system shows collected data to a user was measured). The obtained results show that the proposed VTED architecture is very fast, with some smart sensors (located in Europe) able to self-register and self-configure in a remote cloud (in South America) in less than 3 s and to display data to remote users in less than 2 s.

“…Finally, the most external circle of Figure 1 indicates specific smart areas that are usually involved in the daily activities carried out in a smart campus/university. For example, smart plug-and-play objects [29] may be involved in many university activities, whereas certain environmental sensors are essential for actuating on smart buildings [30]. There are also other fields, like smart agriculture, that may be specific for smart campuses that include in their premises areas for growing certain crops that may require the use of autonomous decision-support systems [31].…”

Towards The Internet of Smart Clothing: A Review on IoT Wearables and Garments for Creating Intelligent Connected E-Textiles

“…• Smart environments rely on a ensuring high-security against cyber threats [260][261][262], and on the constant availability of sensor and actuator devices, whose power consumption is a concern due to the large number of sensor nodes to be deployed. IoT devices require high-security lightweight protocols [263] and cipher suites [264] that optimize the use of resources and the energy consumption. • New IoT architectures will replace current cloud-based systems in certain scenarios like smart health where latency and communications have to be minimized to react fast to events.…”

Development of Novel Bioreactor Control Systems Based on Smart Sensors and Actuators

“…To date, smart sensors have found wide-ranging applications in healthcare, smart driving, smart cities, industrial plants, and IoT networks, as well as in bioreactor control (Lee et al, 2015;Hernandez-Rojas et al, 2018;Perez et al, 2018;Zhang et al, 2018). In one study, Lee et al (2015) introduced a RFIDbased wireless smart-sensor system, composed of a Pt_rGO RFID sensor tag and an RFID-reader antenna-connected network analyzer, to detect hydrogen gas.…”
