Dynamic Channel Assigment   

This work examines the dynamic channel assignment problem (DCA) in wireless networks. DCA typically strives to optimize the problem of frequency or channel reuse while maintaining sufficient spatial separability of the wireless systems that transmit on the same channel. This work considers the impact of spatial and temporally varying channel demand functions. Of particular interest is the effect of considering a cumulative interference metric, rather than one based soley on geographic distance. We consider both mathematical programming approaches as well as algorithms that implement heuristics for real-time channel assignment.

In recent work we examine the application of DCA to the problem of spectrum sharing between licensed and unlicensed users of the RF spectrum.
