Routing and Spectrum Allocation in Broadband Degenerate EPR-Pair Distribution [PDF]
ICC 2024 - IEEE International Conference on CommunicationsWe investigate resource allocation for quantum entanglement distribution over an optical network. We characterize and model a network architecture that employs a single quasideterministic time-frequency heralded EPR-pair source, and develop a routing scheme for distributing entangled photon pairs over such a network.

Using Trust to Establish a Secure Routing Model in Cognitive Radio Network. [PDF]
PLoS ONE, 2015 Specific to the selective forwarding attack on routing in cognitive radio network, this paper proposes a trust-based secure routing model. Through monitoring nodes' forwarding behaviors, trusts of nodes are constructed to identify malicious nodes.

Eavesdropping-Aware Routing and Spectrum Allocation in EONs Using Spread Spectrum Techniques [PDF]
2018 IEEE Global Communications Conference (GLOBECOM), 2018 In this work, eavesdropping-aware routing and spectrum allocation (RSA) techniques are proposed for elastic optical networks (EONs) using orthogonal frequency division multiplexing (OFDM). To introduce physical (optical) layer security and protect these networks against eavesdropping attacks, spread spectrum (SS) with signal overlapping techniques are ...
