Wireless mesh networks (WMNs) are promising networks in the future Internet environments due to their self-configuration and ease of deployment. Although streaming and real time applications are possible using current mobile devices, these applications still suffer from low quality. Because link failures are not reported in congested situations, the(More)
Recent advancement in smart phones enables users to collaborate in mobile environments. Their diverse communication interfaces allow them to interact with nearby devices, enabling the sharing of computing capabilities and resources among collocated users. Given the personal nature of smart phones, the selection of trustworthy users must be incorporated to(More)
Wireless channels exhibit complex signal strength fluctuation over time due to signal propagation effects interacting with a dynamic environment. For accurate simulation of wireless networking protocols, it is important to model wireless channels accurately; without accurate models, simulation results have been shown to be significantly different from(More)
In order to support QoS in wireless ad-hoc networks, each node needs to monitor the network status and to determine whether the current network status satisfies the requirements of an application or not. Since the network requirements on an intermediate node are usually different from those on the end nodes, there is a need to convert the application(More)
—We present a testbed for exploring novel smart refrigerator interactions, and identify three key adoption-limiting interaction shortcomings of state-of-the-art smart fridges: lack of 1) user experience focus, 2) low-intrusion object recognition and 2) automatic item position detection. Our testbed system addresses these limitations by a combination of(More)
