System And Method For Ad Hoc Network Access Employing The Distributed Election Of A Shared Transmission Schedule
Tech ID: 10196 / UC Case 2000-383-0
BACKGROUNDMany scheduling algorithms for time division multiple access (TDMA) have proposed to achieve collision-free transmissions of data frames within each time-slot of a single communication channel in multi-hop packet radio networks. A scheduled-access approach consists of establishing transmission schedules in a way that eliminates collisions and achieves efficient spatial reuse of the available bandwidth. Efficient scheduling with channel reuse can render much higher channel utilization than such fixed assignment approaches as TDMA and frequency division multiple access (FDMA).
DESCRIPTIONScientists at the University of California have developed a novel collision-free medium access control (MAC) protocol that resolves contentions for time division multiple access (TDMA) to a single communication channel.
APPLICATIONSThis new invention has several applications in wireless networks.
