Cross-Layer Anti-Jamming Scheme: A Hierarchical Learning Approach
IEEE Access, 2018 This paper investigates the cross-layer optimization for anti-jamming in the network and MAC layers, in which the jammer can adjust the jamming policies to maximize the jamming effectiveness.

A Countermeasure Against Random Pulse Jamming in Time Domain Based on Reinforcement Learning
IEEE Access, 2020 Pulse jamming is one of the common malicious jamming patterns that can significantly reduce the of wireless communication's reliability. This paper investigates the problem of anti-jamming communication in a random pulse jamming environment.

Intelligent OFDM telecommunication system. Part 1. Model of complex and quaternion systems [PDF]
, 2019 In this paper, we aim to investigate the superiority and practicability of many-parameter transforms (MPTs) from the physical layer security (PHY-LS) perspective. We propose novel Intelligent OFDM-telecommunication systems based on complex and quaternion

On the Impact of Wireless Jamming on the Distributed Secondary Microgrid Control
, 2016 The secondary control in direct current microgrids (MGs) is used to restore the voltage deviations caused by the primary droop control, where the latter is implemented locally in each distributed generator and reacts to load variations.

Uncovering Complex Overlapping Pattern of Communities in Large-scale Social Networks [PDF]
, 2018 The conventional notion of community that favors a high ratio of internal edges to outbound edges becomes invalid when each vertex participates in multiple communities. Such a behavior is commonplace in social networks. The significant overlaps among communities make most existing community detection algorithms ineffective.

Uncovering the Local Hidden Community Structure in Social Networks [PDF]
arXiv, 2021 Hidden community is a useful concept proposed recently for social network analysis. To handle the rapid growth of network scale, in this work, we explore the detection of hidden communities from the local perspective, and propose a new method that detects and boosts each layer iteratively on a subgraph sampled from the original network. We first expand
