Distributed Algorithm for Dynamic Cognitive Ad-hoc Networks
Rohit Kumar, Shaswat Satapathy, Shivani Singh +1
Cognitive ad-hoc networks allow users to access an unlicensed/shared spectrum without the need for any coordination via a central controller and are being envisioned for futuristic…
Distributed Learning Algorithms for Opportunistic Spectrum Access in Infrastructure-less Networks
Rohit Kumar, Sumit J. Darak, Manjesh K. Hanawal +1
An opportunistic spectrum access (OSA) for the infrastructure-less (or cognitive ad-hoc) network has received significant attention thanks to emerging paradigms such as the Interne…
Throughput Optimized Non-Contiguous Wideband Spectrum Sensing via Online Learning and Sub-Nyquist Sampling
Himani Joshi, Sumit J Darak, A Anil Kumar +1
In this paper, we consider non-contiguous wideband spectrum sensing (WSS) for spectrum characterization and allocation in next generation heterogeneous networks. The proposed WSS c…
Learning to Coordinate in a Decentralized Cognitive Radio Network in Presence of Jammers
Suneet Sawant, Rohit Kumar, Manjesh K. Hanawal +1
Efficient utilization of licensed spectrum in the cognitive radio network is challenging due to lack of coordination among the Secondary Users (SUs). Distributed algorithms propose…
