Deep Recurrent Q-Learning Based Beam Steering Strategy for Throughput Maximization in WPCNs
Samannaya Adhikari, Navchetan Awasthi, Siddhartha Sarma
In wireless powered communication networks, medium access control protocols for devices using the harvest-then-transmit strategy must be distributed, low-overhead, and capable of h…
Energy-preserving Indirect-feedback for Wireless Power Transfer
Siddhartha Sarma, Rahul Shrestha, Rohit B. Chaurasiya
Recognising the limitations of various existing channel-estimation schemes for energy beamforming, we propose an energy-preserving indirect feedback-based approach for finding the…
Robust Energy Harvesting Based on a Stackelberg Game
Siddhartha Sarma, Kundan Kandhway, Joy Kuri
We study a Stackelberg game between a base station and a multi-antenna power beacon for wireless energy harvesting in a multiple sensor node scenario. Assuming imperfect CSI betwee…
Robust Power Allocation and Outage Analysis for Secrecy in Independent Parallel Gaussian Channels
Siddhartha Sarma, Kundan Kandhway, Joy Kuri
This letter studies parallel independent Gaussian channels with uncertain eavesdropper channel state information (CSI). Firstly, we evaluate the probability of zero secrecy rate in…
Secure Transmission in Amplify-and-Forward Diamond Networks with a Single Eavesdropper
Siddhartha Sarma, Samar Agnihotri, Joy Kuri
Unicast communication over a network of -parallel relays in the presence of an eavesdropper is considered. The relay nodes, operating under individual power constraints, amplify…
Beamforming for Secure Communication via Untrusted Relay Nodes Using Artificial Noise
Siddhartha Sarma
A two-phase beamforming solution for secure communication using untrusted relay nodes is presented. To thwart eavesdropping attempts of relay nodes, we deliberately introduce artif…
