 +**Abstract:​** ​
 +We introduce a novel paradigm, called rapid on-off-division duplex
 +(RODD), for designing the physical and medium access control (MAC)
 +layers of a wireless ad hoc network formed by half-duplex radios. ​ A
 +node equipped with a half-duplex radio cannot simultaneously transmit and
 +receive useful signals at the same frequency. ​ Unlike in conventional
 +designs, where a node's transmission frames are scheduled away from
 +its reception, RODD lets each node transmit its signal through a
 +unique on-off duplex mask (or signature) over every frame interval,
 +and receive a signal through each off-slot. ​ Over the period of a
 +single frame, every node can transmit a message to its peers, and
 +simultaneously receive a message from each peer.  Thus RODD achieves
 +virtual full-duplex communication using half-duplex radios without
 +complicated scheduling at the frame level. ​ The throughput of RODD is
 +determined under some simple settings, which is significantly larger
 +than that of certain random access schemes. ​ RODD is especially
 +efficient in case the dominant traffic is simultaneous broadcast from
 +nodes to their one-hop peers. ​ Design issues such as peer discovery,
 +synchronization and coding schemes will also be addressed.
 +Dongning Guo joined the faculty of Northwestern University, Evanston,
 +IL, in 2004, where he is currently an Associate Professor in the
 +Department of Electrical Engineering and Computer Science. He received
 +the B.Eng. degree from the University of Science & Technology of
 +China, the M.Eng. degree from the National University of Singapore,
 +and the M.A. and Ph.D. degrees from Princeton University, Princeton,
 +NJ. He was an R&D Engineer in the Center for Wireless Communications
 +(now the Institute for Infocom Research), Singapore, from 1998 to
 +1999. He has held visiting positions at Norwegian University of
 +Science and Technology in summer 2006 and Chinese University of Hong
 +Kong in 2010-2011. He is an Associate Editor of IEEE Transactions on
 +Information Theory in the area of Shannon Theory.
 +Dongning Guo received the Huber and Suhner Best Student Paper Award in
 +the International Zurich Seminar on Broadband Communications in 2000
 +and is a co-recipient of the IEEE Marconi Prize Paper Award in
 +Wireless Communications in 2010. He is also a recipient of the
 +National Science Foundation Faculty Early Career Development (CAREER)
 +Award in 2007. His research interests are in information theory,
 +communications,​ and networking.
