—Unlike traditional networked embedded systems, the Internet of Things interconnects heterogeneous devices from various manufacturers with diverse functionalities. To foster the emergence of novel applications, this vast infrastructure requires a common application layer. As a single global standard for all device types and application domains is(More)
The upcoming deployment of vehicular ad-hoc networks does not only facilitate novel telematics applications, but also poses strong requirements on security. Especially the adoption of active safety applications may raise new threats to road safety if security issues are not properly handled, thus thwarting their initial purpose. In this paper, a special(More)
In this paper we present a special simulation environment , used to analyze the effects of a real-time vehicle-to-vehicle warning-message distribution application on road traffic. For the realization of this environment, a coupling concept for coupling a traffic and a network simulator has been developed and implemented. Besides the simulation environment(More)
The increasing penetration of the real world with embedded and globally networked sensors enables the formation of a Web of Things (WoT), where high-level state information derived from sensors is embedded into Web representations of real-world entities (e.g. places, objects). A key service for the WoT is searching for entities which exhibit a certain(More)
—The increasing penetration of the real world with embedded and globally networked sensors leads to the formation of the Internet of Things, offering global online access to the current state of the real world. We argue that on top of this real-time data, a Web of Things is needed, a software infrastructure that allows the construction of applications(More)
—We present WebPlug, a framework for the emerging Web of Things. It consists of several building blocks which ease integration of things, including their sensors and actuators with the Web. For example, WebPlug supports versioning of and eventing for arbitrary Web resources, like sensor readings, thus simplifying the process of creating physical mash-ups.(More)
We present first experiences of using programmable low-power WiFi modules for connecting things directly to the Web. Instead of relying on dedicated low-power radio technology and specialized protocols, we leverage the ubiquity of IEEE 802.11 access points and the interoperability of the HTTP protocol. Using a loosely coupled approach, we enable seamless(More)
—We are observing an increasing trend of connecting embedded sensors and sensor networks to the Internet and publishing their output on the Web. We believe that this development is a precursor of a Web of Things, which gives real-world objects and places a Web presence that not only contains a static description of these entities, but also their real-time(More)
An increasing number of real-world entities is currently being connected to the Internet and the World Wide Web. We argue that this development is the precursor of a Web of Things (WoT), which in turn provides a promising way to prototype UbiComp applications, by significantly lowering the technical barriers for making things "smart". In this paper, we(More)
We present an open, decentralized, participatory system which realizes location-based services by gently extending the existing World Wide Web. Utilizing a geospatial search engine for such a Web of Places, users are able to consume location-based services generated by arbitrary parties using their mobile phones. Special care has been taken in order to(More)
