Differentiated Service Classes over Multiple Beam Antennas

We present two on-demand MAC protocols to provide differentiated service classes over multiple beam antennas. We use embedded feedback from neighboring nodes to synchronize data communication at multiple beams. The protocols use multilevel queues to organize data, and employ a quality of service (QoS) aware packet scheduler to facilitate disparate traffic flows. We further present a novel paradigm in wireless channel access - receiver initiated choice of sender (RICS). RICS organizes the senders into multilevel queues providing an elegant method to bias the probability of channel award to these nodes. Simulation results demonstrate successful provision for multiple service classes.
