Coding Strategies for Noise-free Relay Cascades with Half-Duplex Constraint
Abstract--Two types of noise-free relay cascades are investigated. Networks where a source communicates with a distant receiver via a cascade of half-duplex constrained relays, and...

Coding-Aware Scheduling for Reliable Many-to-One Flows
We revisit the problem of scheduling the sources transmissions in a many-to-one flow to provide reliable communication between n sources and a single destination. The performance o...

DPF: Fast, Flexible Message Demultiplexing Using Dynamic Code Generation
Fast and flexible message demultiplexing are well-established goals in the networking community [1, 18, 22]. Currently, however, network architects have had to sacrifice one for t...

An optimal algorithm for the distinct elements problem
We give the first optimal algorithm for estimating the number of distinct elements in a data stream, closing a long line of theoretical research on this problem begun by Flajolet...
