DIY interface for enhanced service customization of remote IoT devices: a CoAP based prototype

DIY vision for the design of a smart and customizable world in the form of IoT demands the involvement of general public in its development process. General public lacks the technical depths for programming state-of-the-art prototyping and development kits. Latest IoT kits, for example, Intel Edison, are revolutionizing the DIY paradigm for IoT and more than ever a DIY intuitive programming interface is required to enable masses to interact with and customize the behavior of remote IoT devices on the Internet. This paper presents the novel implementation of such a system enabling general public to customize the behavior of remote IoT devices through a visual interface. The interface enables the visualization of the resources exposed by a remote CoAP device in the form of graphical virtual objects. The VOs are used to create service design through simple operations like drag-and-drop and properties settings. The design is maintained as an XML document, thus being easily distributable and recognizable. CoAP proxy acts as an operation client for the remote device and also provides communication link between the designer and the device. The paper presents the architecture, detailed design, and prototype implementation of the system using state-of-the-art technologies.

Enhanced Service-Oriented Open Sensor Web Architecture with Application Server Based Mashup

Connecting the sensing devices present in the physical world to detect and measure various physical phenomenon such as temperature, humidity, and pollution into a network and presenting them as web resources to the end users have become the goal of a variety of research activities. As the physical network of these devices inherently possesses a heterogeneous nature thus most of the sensor web studies are based on providing domain specific solutions. Service-oriented architecture (SOA) has proven successes to resolve the scalability and evolvability of the web. The present solutions for the SOA based sensor web allows the users to access the sensor data as services but to integrate these services the client must put extra effort to implement the logic. We present an improved SOA based sensor web architecture which offers an easy approach to integrate sensor providers’ services with information provider services and enable the users to access it as a single, integrated, and searchable service. This approach offers the functionality present in the existing solutions as well as an integrated data access or service mashup. We discuss in detail an instance architecture for indoor environment monitoring, based on the proposition of this study.

A Study of Integration Architecture Based on Service Provider in Heterogeneous Sensor Networks

Recently, a lot of sensors are deployed to monitor the context in heterogeneous environments. A sensor is an engineering point of view as a device that collect the phenomenon signal. The sensor middleware is to enable clients to view context data on Internet. In this paper, we propose an integration architecture based on service provider using multiple sensor middleware in heterogeneous large-scale sensor networks.
