The Power of Abstract MAC Layer: A Fault-tolerance Perspective
Qinzi Zhang, Lewis Tseng
This paper studies the power of the "abstract MAC layer" model in a single-hop asynchronous network. The model captures primitive properties of modern wireless MAC protocols. In th…

Fault-tolerant Consensus in Anonymous Dynamic Network
Qinzi Zhang, Lewis Tseng
This paper studies the feasibility of reaching consensus in an anonymous dynamic network. In our model, anonymous nodes proceed in synchronous rounds. We adopt a hybrid fault m…

Echo-CGC: A Communication-Efficient Byzantine-tolerant Distributed Machine Learning Algorithm in Single-Hop Radio Network
Qinzi Zhang, Lewis Tseng
In this paper, we focus on a popular DML framework -- the parameter server computation paradigm and iterative learning algorithms that proceed in rounds. We aim to reduce the commu…
