While unstructured P2P systems have been embraced widely in mobile ad-hoc networks (MANETs), the applicability of structured approaches like distributed hash tables (DHTs) to such settings remains controversial. Existing research delivers promising empirical results addressing the concerns about performance, complexity, and reliability, but does not analyze the principles of combining DHTs and MANETs. This paper identifies and discusses the fundamental implications of non-infrastructural networks for DHTs and analyzes solutions to these challenges

Although file and printer sharing services have been deployed almost ubiquitously for a long time as part of Microsoft Windows, only recent peer-to-peer applications popularized file-sharing on a global scale. As theWindows CIFS protocol was designed for local area networks, its use has been confined to relatively small environments. We propose a mechanism to set up spontaneous virtual groups that allow to use legacy Windows file and printer sharing globally in virtual LANs.
In this position paper we propose an evaluation framework for networked mobile gaming, consisting of user, group, communication, and environment models. Each of these components acts as a detailed representation of re...

Energy consumption is a crucial characteristic of sensor networks and their applications as sensor nodes are commonly battery-driven. Although recent research focuses strongly on energy-aware applications and operating systems, energy consumption is still a limiting factor. Once sensor nodes are deployed, it is challenging and sometimes even impossible to change batteries. As a result, erroneous lifetime prediction causes high costs and may render a sensor network, useless before its purpose is fulfilled. In this paper, we present AEON (accurate prediction of power consumption), a novel evaluation tool to quantitatively predict energy consumption of sensor nodes and whole sensor networks. Our energy model, based on measurements of node current draw and the execution of real code, enables accurate prediction of the actual energy consumption of sensor nodes. Consequently, it prevents erroneous assumptions on node and network lifetime. Moreover, our detailed energy model allows us to compare different low power and energy aware approaches in terms of energy efficiency. Thus, it enables a highly precise estimation of the overall lifetime of a sensor network.
