Decentralized Reinforcement Learning Based Anti-Jamming Communication for Self-Organizing Networks

IEEE Wireless Communications and Networking Conference, 2021
This paper investigates the problem of decentralized spectrum sharing in self-organizing networks against a dynamic and unknown jamming environment using reinforcement learning. In the network, the anti-jamming spectrum sharing has to not only coordinate

Dynamic Spectrum Anti-Jamming Communications: Challenges and Opportunities

IEEE Communications Magazine, 2020
Due to the openness of the transmission medium, it is necessary for radio systems to have anti-jamming abilities. Traditional anti-jamming methods such as sequence-based frequency hopping and direct sequence spread spectrum have shortcomings of low spectral efficiency and fixed communication patterns.

Multi-Subchannel Spread Spectrum for Anti-jam Communications

2012 International Conference on Industrial Control and Electronics Engineering, 2012
This paper presents a novel anti-jamming wireless communication system called Multi-Subchannel Spread Spectrum (MSCSS). It is based on M-ary spread spectrum (SS), direct sequence spread spectrum (DS-SS), orthogonal frequency division multiplexing (OFDM), and multi-carrier code division multiple access (MC-CDMA).

A self-recovery scheme in anti-jamming communications

1996 IEEE International Conference on Acoustics, Speech, and Signal Processing Conference Proceedings, 2002
By exploiting the spatial diversity among different signals, anti-jamming communications can be accomplishing using antenna arrays. In this paper, we discuss the self-recovery problem for antenna array wireless systems after the communication link is broken due to abrupt environmental changes.

Randomized positioning DSSS for anti-jamming wireless communications

2016 International Conference on Computing, Networking and Communications (ICNC), 2016
Traditional anti-jamming approaches like Frequency Hopping Spread Spectrum (FHSS) and Direct Sequence Spread Spectrum (DSSS) require the sender and the receiver to share a secret key prior to their communication. If this key is compromised by the jammer, the jammer can then generate the frequency hopping patterns or the spreading codes used by the ...

Zero-Communication Seed Establishment for Anti-Jamming Techniques

Proceedings 2014 Workshop on Security of Emerging Networking Technologies, 2014
In an environment perturbed by malicious interference, establishing a reliable wireless connection without shared secrets typically relies on uncoordinated spread spectrum methods, such as UFHSS or UDSSS. These methods offer a lowthroughput channel for the exchange of key contributions with the goal to establish a shared secret.
