Bits Through Deterministic Relay Cascades with Half-Duplex Constraint
Tobias Lutz, Christoph Hausl, Ralf Kötter
Consider a relay cascade, i.e. a network where a source node, a sink node and a certain number of intermediate source/relay nodes are arranged on a line and where adjacent node pai…
An Algebraic Watchdog for Wireless Network Coding
MinJi Kim, Muriel Medard, Joao Barros +1
In this paper, we propose a scheme, called the "algebraic watchdog" for wireless network coding, in which nodes can detect malicious behaviors probabilistically, police their downs…
Communication over Finite-Field Matrix Channels
Danilo Silva, Frank R. Kschischang, Ralf Kötter
This paper is motivated by the problem of error control in network coding when errors are introduced in a random fashion (rather than chosen by an adversary). An additive-multiplic…
Coding Strategies for Noise-Free Relay Cascades with Half-Duplex Constraint
Tobias Lutz, Christoph Hausl, Ralf Kötter
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 networks…
