Current centralized cloud datacenters provide scalable computation- and storage resources in a virtualized infrastructure and employ a use-based "pay-as-you-go" model. But current mobile devices and their resource-hungry applications (e.g., Speech-or face recognition) demand for these resources on the spot, though a mobile device's intrinsic characteristic is its limited availability of...
Consumption of multimedia content is moving from a residential environment to mobile phones. Optimizing Quality of Experience -- smooth, quick, and high quality playback -- is more difficult in this setting, due to the highly dynamic nature of wireless links. A key requirement for achieving this goal is estimating the available bandwidth of mobile devices. Ideally, this should be done quickly and...
Wireless intelligent transport systems based on Car-to-X communication technology are about to enter the mass market in upcoming years. Thereby, efficient and reliable security systems are a core point of concern in system design. Currently regarded digital signature schemes using pseudonym certificates can introduce significant overhead into the highly bandwidth restricted system. Thus, mechanisms...
Delay Tolerant Networks (DTNs) are sparse mobile ad-hoc networks in which there is typically no complete path between the source and destination. To increase the reliability of message delivery, multi-copy routing is often used at the expense of high buffer and bandwidth overhead. While much work has been done in the design of forwarding algorithms, little work has focused on studying forwarding under...
