Communication with smart objects currently only works in isolated, sometimes even proprietary islands. This lack of interoperability limits the value of smart objects connected to the Internet of Things (IoT). We propose to use the Extensible Messaging and Presence Protocol (XMPP) to connect IoT islands. XMPP is inherently federated, secure, globally scalable and designed for collaboration. We use...
With the integration of smart objects into the Internet with the help of tiny IP stacks, a direct connection between these objects and ordinary computational devices can be realized at the IP layer. As IP alone cannot ensure an automatic integration at the higher layers, an homogeneous access via services (e.g., discovery, self-configuration) for the Internet of Things vision should be provided for...
The vision of ubiquitous communication is driven by increasing user mobility and the need to collaborate. Mobile collaborative applications, such as mobile audio/video conferences, collaborative writing, social networks, and mobile gaming, are already important parts of human interaction. In this paper, we present the uBeeMe platform that supports the development of cooperative applications for ubiquitous...
Crises such as the Fukushima incident in Japan showed the demand for flexible and easy-to-use monitoring and communication systems to support post-disaster management (i.e. the organization of actions in the follow-up of disasters), especially when critical infrastructure is affected. Such systems can effectively only be realized with a merging of various device classes and the integration of mobile...
A flexible and easy-to-use disaster management system is vital to provide rescue teams with accurate information and communication. This work promotes a post disaster management system that provides communication in infrastructure as well as ad hoc scenarios and that supports on demand creation of joint task forces. The system is build upon the Extensible Message and Presence Protocol (XMPP). Scenarios,...
The Internet of Things vision states that sensors and actuators shall be integrated into the global Internet to facilitate an interaction with and integration of the physical environment. The development of enabling technologies like uIPv6 and 6LoWPAN provide the basic requirements for this interconnection. However, a seamless Internet-connection and interconnection between sensors and actuators can...
An important challenge for the Internet of Things is the gap between scientific environments and real life deployments. Smart objects need to be accessible and usable by ordinary users through familiar software and access technologies to facilitate any interaction and to increase their acceptance rate. This work deals with a seamless integration, discovery, and employment of smart objects into the...
Recent crises like the Fukushima incident in Japan show that there is a demand for flexible and easy-to-use communication and sensor systems to support post-disaster management (i.e. the organization of actions in the follow-up of disasters), especially when critical infrastructure is affected. This paper introduces a system design that combines mobile XMPP-based and sensor-equipped devices with the...
