Many networking applications implement topology adaptations to cope with network dynamics. Related work focuses on the specific application, lacking a general model for topology adaptations. In this paper, we analyze 14 topology adaptations from two different application domains. Based on the derived characteristics, we propose a general topology adaptation model. We present the Topology Adaptation...
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...
Topology control for wireless sensor networks is a thriving research field with no real-world adoption. This is partly due to the fact that a large number of approaches is focused on providing theoretical bounds. However, even more recent practical approaches are not being implemented. Integrating topology control with medium access control (MAC) and routing into a standard communication stack seems...
Numerous topology control algorithms for wireless sensor networks exist. Typically, these algorithms optimize general network metrics like the transmission range of sensors. Being of general nature, they suit application-specific requirements insufficiently; e.g., application-specific communication patterns may favor links that the general algorithm will remove.
Topology control for Wireless Sensor Networks (WSN) is a frequently tackled challenge, for which no satisfying general solution for realistic deployments has been found to the current day. Aiding to minimize unnecessary transmissions, it nevertheless represents a crucial function of WSN, in the light of their pursuit of efficiency. kTC is a new WSN topology control that unlike prior art neither relies...
