EURASIP Journal on Wireless Communications and Networking, 2012

The explosions of Internet of Things industry have been bringing more and more smart devices (SDs) into business and people's daily life. This creates new opportunities to build applications that better integrate real-time state of the physical world and requires agility for the software to accommodate customers' requirements. Nevertheless, devices are usually provided by different manufacturers, and applications are independently constructed based on their own infrastructures with little interoperability. Web of Things concept has enabled the interoperability between devices by RESTful web service in a lightweight way; however, it make less efforts to discuss how to integrate devices into complex business environment. Service-Oriented Architecture and Business Process Management approach are becoming applicable to embedded real-world devices and provide flexible service composition. However, it is based on WS-* web service specification which is too heavy and complex for devices and not compatible to RESTful style. In such situation, integrating device into business application with simplicity and providing agility composition of service based on device are significant challenges. We propose a web-based two-layered integration framework that enables SD to integrate with each other via lightweight interface and other back-end applications into agile business process. A real-life use case on elderly care is studied in detail based on the framework.

Abstract—As we advance towards an Internet of Things (IoT), it becomes necessary to conceive new forms of interaction between people and the everyday objects that surround them. A world full of internetworked objects with sensing capabilities requires effective tools in order to interpret contextual data gathered from the environment and services provided by smart objects. We aim to provide a browser for the IoT through what have referred to as a sentient visor.

The "Web of Things" vision promotes the integration of smart devices into web, using web technologies and protocols as underlying interaction mechanisms with smart devices. Technically many phones include various sensors and provide a largescale sensing platform. To make this functionality available to a large number of (web) developers our research aims at easing the creation of applications that use mobile context data (e.g., movement data). We present a sensing platform for mobile devices, called SENSE-SATION, which gathers and stores available information on a mobile phone and makes this information directly accessible via RESTful web services-locally and remotely. By using a concept of virtual sensors, the platform supports the full development process, from the initial idea via adapting/extending the platform to incremental development of virtual sensors and applications via Web 2.0 controls. Hence, (web) developers can create arbitrary context-aware applications that make use of mobile hardware capabilities without touching mobile phone programming at all. In this paper we discuss the design issues and provide case studies to describe how this platform can empower the development of social, context-aware applications.

Supporting human users when interacting with smart devices is important to drive the successful adoption of the Internet of Things in people's homes and at their workplaces. In this poster contribution, we present a system that helps users control Web-enabled smart things in their environment. Our approach involves a handheld interaction device that recognizes smart things in its view using state-of-the-art visual object recognition techniques. It then augments the camera feed with appropriate interaction primitives such as knobs or buttons for control, and can also display measured values, for instance, when recognizing a sensor. The interaction primitives are generated from user interface descriptions that are embedded in the Web representations of the smart things. Our prototype implementation achieves frame rates that allow for interactive use of the system by human users, and indeed proved to facilitate the interaction with smart things in a demonstration testbed in our research group.

The Web of Things vision aims to turn real-world objects into resources of the Web. The creation of accessible and addressable Virtual Objects, i.e. services that expose the status and capabilities of connected real-world objects using REST APIs, allows for new machine-to-machine interactions to be designed but also for a new user experience to be shaped. Indeed, the change brought about by the connectivity of objects and their ability to share information raises design issues that have to be considered by manufacturers and service providers alike. In this paper, we present an approach to the Web of Things based on both technical and user-centered points of view. We argue that new user interfaces have to be designed to allow users to visualize and interact with virtual objects and environments that host them. We illustrate our vision with an interaction mockup that allows the user to navigate the Web of Things through three devices (a smart phone, a web tablet and a desktop web browser).

In this paper we outline the challenges of Web API management in Internet of Things (IoT) projects. Web API management is a key aspect of service-oriented systems that includes the following elements: metadata publishing, access control and key management, monitoring and monetization of interactions, as well as usage control and throttling. We look at how Web API management principles, including some of the above elements, translate into a world of connected devices (IoT). In particular, we present and evaluate a prototype that addresses the issue of managing authentication with millions of insecure low-power devices communicating with non-HTTP protocols. With this first step, we are only beginning to investigate IoT API management, therefore we also discuss necessary future work.

Household appliances are being equipped with embedded micro-controllers and wireless transceivers, offering smart behavior. These augmented appliances form wireless networks and transform residential areas into smart homes. Advancements such as the effective penetration of the Internet in embedded computing and the promising practice of the Web of Things, allow the realization of Web-oriented smart homes. In a previous work, we developed a Web-based application framework for smart homes, supporting concurrent interaction from multiple family members. In this paper, we improve the functionality of our system by including a 6LoWPAN-based wireless sensor network inside the home environment, addressing issues such as device discovery and service description. Web techniques such as HTTP caching and push messaging, facilitate the efficient operation of a fully Web-based smart home. Through a technical evaluation, we show the benefits of directly Webenabling embedded sensors in terms of performance and energy conservation. The development of a Web-based graphical application abstracts home automation procedure for typical residents.

In recent years IoT (Internet of Things) is gaining interest among researchers and many IoT development platforms, SDK’s have been proposed. There are lots of low powered, efficient devices available in market which can be used to create IoT solutions. The main drawbacks of IoT is that every manufacture proposed it owns protocol and provide their own API’s to work with it. You need to be an avid programmer to implement, understand, customized and use this API’s. Since lots of these libraries are open source not much information can be gathered online. To solve this protocol agnostic problem in IoT many researchers are now focusing on WoT i.e. Web of Things. The main advantage of implementing WoT is that we can use familiar Web protocols to build up our solutions. In this paper we will discuss SOA architecture, proposing a high level WoT network implementation at home-using embedded devices and Web protocols like REST web services and JavaScript to achieve interoperability. We will also discuss security concerns in WoT and best practices to avoid vulnerabilities.

– In 21st century the people wants the world on their hands. It outlets the revolutions of computing and smart environment. Some technologies like Ubiquitous/pervasive and ambient intelligence satisfy the maximum need of smart world but these technologies are not tightly coupled with internet, so the people needs another technology extension. Internet of Things (IoT) is an ideal emerging technology to influence the internet and communication technologies. Simply " Internet of Things " connects " living and non living things " through " internet ". Traditionally in the object oriented paradigm everything in the world is considered as an object, but in the IoT paradigm everything in the world is considered as a smart object, and allows them to communicate each other through the internet technologies by physically or virtually. IoT allows people and things to be connected Anytime, Anyplace, with Anything and Anyone, by using ideally in Any path/network and Any service. This paper proposes architecture to enable the users to control and monitor smart devices through internet. It creates an interface between users and smart home by using GSM and internet technologies, or it simply creates GSM based wireless communication from the web server into the smart home. In this architecture the users give commands through web then the users inputs are converted into GSM-SMS commands. These commands are sent to embedded system module (embedded system directly connect with devices) through GSM network, and finally the user commands are parsed and executed by microcontroller to control any electronic objects like home appliances, lights, etc and it sends the acknowledgement. The embedded system module can place anywhere in the world and it will controlled by IoT Agent through GSM network.
