T-Lohi: A New Class of MAC Protocols for Underwater Acoustic Sensor Networks
This paper introduces T-Lohi, a new class of distributed and energy-efficient media-access protocols (MAC) for underwater acoustic sensor networks (UWSN). MAC design for UWSN fac...

Tomlinson-Harashima Precoding for Broadcast Channels with Uncertainty
— We consider the design of Tomlinson-Harashima (TH) precoders for broadcast channels in the presence of channel uncertainty. For systems in which uplink-downlink reciprocity is ...

Scheduling in Mobile Ad Hoc Networks with Topology and Channel-State Uncertainty
—We study throughput-optimal scheduling/routing over mobile ad-hoc networks with time-varying (fading) channels. Traditional back-pressure algorithms (based on the work by Tassiu...

Throughput-Optimal Scheduling in Multichannel Access Point Networks Under Infrequent Channel Measurements
—We consider the problem of uplink/downlink scheduling in a multichannel wireless access point network where channel states differ across channels as well as users, vary with tim...
