Design and Simulation of Spectrum Management Methods for Wireless Local Area Networks

Wireless communication has become an integral part of daily life which results in an increasing number of wireless LAN devices deployed both in business, educational and residential environments and thus in increasing mutual interference between these devices. In addition, the requirements for the transmission platforms are increasing: voice-over-IP or video telephony rely on quality-of-service guarantees which have to be maintained even in case of concurrent access of multiple users.

This work discusses possible solutions for the above-mentioned problems based on research work which the author did in two projects funded by the German Research Foundation (Deutsche Forschungsgemeinschaft, DFG): In CoCoNet, automated spectrum management between neighbouring networks to reduce mutual interference was investigated while in XLayer, the focus was the resource allocation of a wireless LAN base station which serves a number of mobile terminals with data flows.
