Generalized Gray Codes for Local Rank Modulation
Eyal En Gad, Michael Langberg, Moshe Schwartz +1
We consider the local rank-modulation scheme in which a sliding window going over a sequence of real-valued variables induces a sequence of permutations. Local rank-modulation is a…
Binary Causal-Adversary Channels
Michael Langberg, Sidharth Jaggi, Bikash Kumar Dey
In this work we consider the communication of information in the presence of a causal adversarial jammer. In the setting under study, a sender wishes to communicate a message to a…
Codes against Online Adversaries

In this work we consider the communication of information in the presence of an online adversarial jammer. In the setting under study, a sender wishes to communicate a message to a…
Adversarial Models and Resilient Schemes for Network Coding
Leah Nutman, Michael Langberg
In a recent paper, Jaggi et al. (INFOCOM 2007), presented a distributed polynomial-time rate-optimal network-coding scheme that works in the presence of Byzantine faults. We revisi…
