With huge popularity and high resource efficiency JavaScript has gone well beyond the web and reached out for many other areas. The rapidly growing Internet of Things is no exception. This talk will discuss why we think that JavaScript is a good option to kick-start building your own Internet of Things. Solutions we have been used for building an end to end IoT system using JavaScript will be discussed. An introduction to JerryScript, an ultra-light JavaScript engine from Samsung, will be given to address the issue of resource restriction in embedded devices. It is followed by a look at JavaScript platforms based on JerryScript that provide direct JavaScript APIs to developers. The open gateway framework is node.js based and targets at decentralized ‘Internet of Things’ with privacy and security in mind. This talk is supported by a demo.

IoT.js - A JavaScript platform for the Internet of Things

IoT.js is a javascript platform that aims to provide inter-operable services for IoT world. Powered by JerryScript, an ultra-lightweight modular JavaScript engine, the platform is designed to bring the success of Node.js to constrained IoT devices. To address interoperability, IoT.js has provided a Node.js friendly architecture and comes with a subset of Node.js APIs. Since Samsung OSG first presented IoT.js in FOSDEM in 2016, the platform has been through a rapid growth in last couple of years. With a lot active high-quality contributions from the IoT.js and JerryScript open source community, IoT.js has released version 1.0 in July 2017 which presented a rich set of features, hardware and tool supports for developers. In this talk, we are looking at recent developments in IoT.js and share our vision for future plans. The talk is supported by a demo of iot.js running on constrained device seamlessly connects to node.js for third party cloud access.

The vast majority of devices in IoT space are constrained devices. A lot recent developments and standard initiatives have addressed connectivity solutions for constrained devices by introducing protocols such as CoAP and MQTT. With connectivity in place, the next challenge is how these devices can make use of the existing Web services. This talk introduces the web service interface (WSI) layer in IoTivity framework to address this challenge. A demo on how IoT devices can seamlessly access cloud Services with the helps of WSI in IoTivity stack will be given.

Web services have been one of the latest technological changes that are revolutionizing the world of business and our everyday lives. With the huge expanding of Things in the IoT world, the vision of accessing web services is not only for smart device any more. The existences of trillions of constraied devices brings great challenges and possibly opportunities of seamless interoperability with existing web services.

In this talk we will discuss the technical challenges from various aspects. A general review of existing solutions in industry and proposals/initiatives in research and standard will be given. To introduce the appoach used in IoTivity, we first give a detailed background introduction on IoTivity framework. Based on this we will discuss that with some of the most compelling applications in the IoT space involve rich and differentiated interactions between people and devices, a interface layer is required to provide features to help web service developers to introduce and tailor their service to the IoT context. This talk is supported by a demo on how IoT devices can seamlessly access cloud Services with the helps of web service interface layer in IoTivity stack.
