>>>ABSTRACT:
>>>Rhee presents a distributed implementation of RAND, a randomized time slot
>>>scheduling algorithm, called DRAND. DRAND runs in O(d) time and message
>>>complexity where d is the size of a two-hop neighborhood in a wireless
>>>network while message complexity remains O(d), assuming that message
>>>delays can be bounded by an unknown constant. DRAND is the first fully
>>>distributed version of RAND. The algorithm is suitable for a wireless
>>>network where most nodes do not move, such as wireless mesh networks and
>>>wireless sensor networks. We implement the algorithm in TinyOS and
>>>demonstrate its performance in a real test bed of Mica2 nodes. The
>>>algorithm does not require any time synchronization and is shown to be
>>>effective in adapting to local topology changes without incurring global
>>>overhead in the scheduling. Because of these features, it can also be used
>>>even for other scheduling problems such as frequency or code scheduling
>>>(for FDMA or CDMA) or local identifier assignment for wireless networks
>>>where time synchronization is not enforced.

>>>Injong Rhee received his Ph.D. from the University of North Carolina at

>>>of the company until year 2002. His research interests are computer
>>>networks, congestion control, wireless networks, multimedia networking,
>>>distributed systems, and operation systems. He is an inventor of several

>>>world and is currently the default TCP algorithm used in Linux 2.6 and up.
>>>He received NSF Early Faculty Career Development Award in 1999 and New
>>>Inventor's award from NCSU.
