The following are the main issues to be solved: While IoT solves networking problems, WoT is focused exclusively on application layer protocols and tools. In response to this need, the Web of Things (WoT) arises as a concept that creates an abstraction layer above IoT, modifying the already existing web protocols that have provided scalability and interactivity to applications and that allow web developers to make use of the data and services collected from IoT devices. In addition, there is a growing Do It Yourself (DIY) community of makers that devise new products and customized IoT developments that are facing the mentioned challenges everyday. This heterogeneity makes it difficult to integrate intelligent sensors from different manufacturers into an application or an IoT system. Moreover, in this diverse IoT landscape, there is a lack of spread of interoperability standards for all layers, from the physical to the application layer. There are currently in the market hundreds of IoT manufacturers that develop prototypes, solutions, and proprietary SDKs. Therefore, in order to minimize sensor node consumption, it is necessary to optimize the firmware of the deployed sensors and make use of efficient communication technologies and lightweight protocols, which are also able to reduce response latencies and improve Quality of Service (QoS). In the last several years, intelligent sensor nodes have reduced in size (which is why they are also called motes), and, despite the current progress on energy harvesting techniques, they still depend on batteries to operate. In addition, sensors have to provide plug-and-play capabilities that enable to detect active sensors in a fast and accurate way. ![]() Thus, intelligent sensors, besides being able to process the collected information, have to perform additional computing tasks, exchange data through wired or wireless networks, add connectivity with actuators, or include some kind of display. The information of such elements can be managed locally or from higher layers (through a gateway, a cloud computing system, and even through a blockchain ).ĭue to the need for a greater abstraction level to implement advanced applications, the IoT has had to evolve. Īt the foundations of every IoT platform are the “things” that are intelligent sensors and actuators usually connected to wireless networks (thus creating a Wireless Sensor Network (WSN)). These applications are increasingly heterogeneous, complex, and demanding. Examples of IoT applications can be found for smart cities, smart homes, e-health, intelligent transportation, critical infrastructures, precision agriculture, smart factories, or for Industry 4.0. IoT infrastructure engages in multiple application domains and in emerging businesses where physical and virtual devices are able to inter-operate through a data network without human intervention. In fact, the IoT market has maintained a sustainable growth in the last several decades and is estimated to grow to 20 billion devices in 2020. The Internet of Things (IoT) is no longer a novel concept and has already become an everyday term. 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. Specifically, user experience was quantified empirically (i.e., how fast the system shows collected data to a user was measured). ![]() NAVICAT FOR MYSQL 2016 SERIAL GITHUB BLUETOOTHIn 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. 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. Such protocols enable the development of novel IoT solutions while guaranteeing low latency, low power consumption, and the required Quality of Service (QoS). It makes use of new lightweight protocols that allow sensors to self-describe, auto-calibrate, and auto-register. 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). ![]()
