Transmission failures are common in wireless networksdue to dynamic channel conditions and unpredictableinterference. To efficiently recover from failures, we proposea smart retransmission scheme where the receiver combinesinformation received from multiple failed transmissions associatedwith the same frame. The smart retransmission hastwo distinguishing features: (i) it can simultaneously supportpartial...
This paper proposes a novel routing protocol, DM+, to achieve distributed spatial multiplexing gain in wireless mesh networks. It lets multiple nodes simultaneously send and receive different streams over each hop. To realize this goal, we propose an optimization framework that jointly optimizes spatial multiplexing, routing, and rate limits while taking into account wireless interference. We further...
Distributed multiple-input multiple-output (MIMO) promises a dramatic capacity increase. While significant theoretical work has been done on distributed MIMO at the physical layer, how to translate the physical layer innovation into tangible benefits to real networks remains open. In particular, realizing multi-point to multi-point MIMO involves the following challenges: (i) how to accurately synchronize...
