Workshop on Mobile Computing Systems and Applications ({HotMobile}) Doctoral Consortium}, year = {2009}, month = {February}, organization = {{ACM}}, note = {extended abstract}, abstract = {Increasing spatial reuse of spectrum is fundamental to improving the capacity and usefulness of large wireless networks. Steerable and adaptive antennas facilitate reuse, and a number of MAC-layer protocols have been developed for them. Existing protocols, however, do not allow the MAC (or scheduling) process to fully consider the capabilities of antenna reconfiguration, or vice-versa. Without such integration between MAC scheduling and physical antenna configuration, a ``chicken-and-egg'' problem exists: If antenna decisions are made before scheduling, they cannot be optimized for the communication that will actually occur. If the scheduling decisions are made first, the scheduler cannot know what the actual interference and signal strength properties of the network will be. To take full advantage of the dynamic capabilities of an advanced antenna system, MAC-layer processes need to know about not just any particular RF-level configuration, but about the range of \emph{possible} configurations. This research has two goals: To produce a fully-integrated algorithm for STDMA scheduling and beam steering, and to \emph{systematically} evaluate the costs and benefits of different approaches to such integration. Our approach to this research is based on a combination of mathematical analysis, simulation, implementation and deployment, and empirical measurement.}, owner = {andersoe}, timestamp = {2009.05.01} }
