In disaster situations, the coordination of rescue missions is a difficult task. The person in charge makes decisions under pressure, which could lead to inappropriate instructions to rescuers and could cost many lives. The aim of DisVis 2.0 approach is to release pressure from those responsible by providing decision support using predictive human-centric disaster simulations for infrastructure-less...
Reliable communications are crucial for the success of emergency response and management. However, today's technologies used by rescuers and civilians mainly rely on either centralized or specialized emergency approaches, which reveal individual issues especially in infrastructure- less emergency situations (e.g., blackout). In this paper, we present a customary home router upgraded as self- sustaining...
Graph-based topology control adapts wireless topologies to achieve certain target graph structures. Wireless sensor networks seem well-suited for the expectations (in particular those on provided energy savings) raised by topology control. Nevertheless, topology control has never made the breakthrough in real-world deployments. This work explores the reasons for this, identifying five practical obstacles...
This work demonstrates the effects of multi-layer adaptivity for a wireless live video streaming scenario. We investigate a specific type of adaptations, the so-called transitions, which switch between different network mechanisms during the runtime of an application. In comparison to a pure configuration adaptation, a transition is beneficial because a system may select those mechanisms that perform...
