System and Method for Ad Hoc Network Access Employing the Distributed Election of a Shared Transmission Schedule

Increases bandwidth utilization via competition for empty-time slotsProvides collision-free access and priority-based channel access within ad hoc networks for high performance

Communication networks: a system that allows collision-free channel access within an ad hoc network while maximizing the use of available bandwidth

Scientists at the University of California, Santa Cruz have developed a novel topology-dependant TDMA method that acts as a collision-free medium access control (MAC) protocol that resolves contentions for time division multiple access (TDMA) for a single communication channel. By employing distributed election of a shared transmission schedule, the system can allow for collision-free access and increase the use of bandwidth.
