Distributed Quantized Detection of Sparse Signals Under Byzantine Attacks

no code implementations27 Apr 2023 Chen Quan, Yunghsiang S. Han, Baocheng Geng, Pramod K. Varshney

The proposed detectors can achieve the detection performance close to the benchmark likelihood ratio test (LRT) detector, which has perfect knowledge of the attack parameters and sparsity degree.

Human-machine Hierarchical Networks for Decision Making under Byzantine Attacks

no code implementations25 Jan 2023 Chen Quan, Baocheng Geng, Yunghsiang S. Han, Pramod K. Varshney

Consequently, the proposed scheme can effectively defend against Byzantine attacks and improve the quality of human sensors' decisions so that the performance of the human-machine collaborative system is enhanced.

Efficient Ordered-Transmission Based Distributed Detection under Data Falsification Attacks

no code implementations18 Jul 2022 Chen Quan, Nandan Sriranga, Haodong Yang, Yunghsiang S. Han, Baocheng Geng, Pramod K. Varshney

In distributed detection systems, energy-efficient ordered transmission (EEOT) schemes are able to reduce the number of transmissions required to make a final decision.

Lower Bound on the Optimal Access Bandwidth of ($K+2,K,2$)-MDS Array Code with Degraded Read Friendly

no code implementations4 Feb 2021 Ting-Yi Wu, Yunghsiang S. Han, Zhengrui Li, Bo Bai, Gong Zhang, Liang Chen, Xiang Wu

Accessing the data in the failed disk (degraded read) with low latency is crucial for an erasure-coded storage system.
