Adaptives hierarchisches Ray Tracing Verfahren zur parallelen Berechnung der Wellenausbreitung in Funknetzen
The continuous demand for mobile communications leads to the development of new cellular networks for transmission of data, voice and video sequences. Already established GSM mobile cellular networks, a great economic success of the last decade, will be slowly upgraded to and eventually replaced by …

Approximation algorithms for spectrum allocation and power control in wireless networks
Wireless networks have to operate despite the effects of interference. Therefore, it is a vital prerequisite to have algorithms that suitably manage wireless spectrum accesses. In this thesis, we design and analyze such algorithms from a theoretical perspective, striving for provable performance …
