Current surveys and forecast predict that the num ber of wireless devices is going to increase tremendously. These wireless devices can be computers of all kinds, notebooks, netbooks, Smartphones and sensor nodes that evolve into real world scenarios forming a "Real-World-Internet" in the future.In our work we focus on the Future Internet with small battery driven devices forming the "Internet of Things". In recent networking research, testbeds gain more and more attention, especially in the context of Future Internet and wireless sensor networks (WSNs). This development stems from the fact that simulations and even emulations are not considered sufficient for the deployment of new technologies as they often lack realism.Experimental research on testbeds is a promising alternative that can help to close the gap.The deployment of testbeds is challenging and user and operator requirements need to be considered carefully. Therefore, the goal is to design an architecture that allows operators of WSN testbeds to offer numerous users access to their testbeds in a standardized flexible way that matches these requirements.In this paper we first identify some of the requirements, then introduce the architecture and general concepts of our WISEBED approach and show how this architecture meets the requirements of both groups. We give an overview of existing WISEBED compatible WSN testbeds that can be used for experimentation today. Main focus in this paper compared to previous work is to address the perspective of both users and operators on how to experiment or respectively operate a WSN testbed based on WISEBED technology.
The number of networked smart devices available in everyday environments is rapidly increasing; however, many current devices adopt mutually incompatible networks, protocols, and application programming interfaces. As such, creating mobile applications that dynamically discover and integrate ambient functionality across multiple vertical markets remains challenging. In this paper, we introduce a novel middleware framework, called Ambient Control, which enables commodity mobile devices (e.g., smart-phones) to dynamically mediate control messaging between incompatible smart devices situated in the user's environment. Ambient Control enables a variety of control capabilities and protocol translation services to be dynamically installed into a user's mobile device on-demand using plug-ins. The approach also features an intuitive "Tap to Interact" workflow that allows a user to tap nearby smart devices with a smart-phone to install required interaction plug-ins and automatically "wire" them together in interesting and potentially unforeseen ways. In this paper, we present a detailed overview of the Ambient Control framework, introduce our fully functional prototype, and present an evaluation indicating that the prototype provides efficient messaging performance and imposes low processing and memory overhead, making it suitable for deployment on many commodity mobile devices.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
