Opportunistic User Scheduling for Secure RIS-aided Wireless Communications
Burhan Wafai, Sarbani Ghose, Chinmoy Kundu +2
In this paper, we provide expressions for the secrecy outage probability (SOP) for suboptimal and optimal opportunistic scheduling schemes in a reconfigurable intelligent surface (…
Jointly Optimal RIS Placement and Power Allocation for Underlay D2D Communications: An Outage Probability Minimization Approach
Sarbani Ghose, Deepak Mishra, Santi P. Maity +1
In this paper, we study underlay device-to-device (D2D) communication systems empowered by a reconfigurable intelligent surface (RIS) for cognitive cellular networks. Considering R…
Secrecy of Opportunistic User Scheduling in RIS-Aided Systems: A Comparison with NOMA Scheduling
Burhan Wafai, Sarbani Ghose, Chinmoy Kundu +2
In this paper, we propose an opportunistic user scheduling scheme in a multi-user reconfigurable intelligent surface (RIS) aided wireless system to improve secrecy. We derive the s…
Secrecy Outage of Dual-hop Regenerative Multi-relay System with Relay Selection
Chinmoy Kundu, Sarbani Ghose, Ranjan Bose
Relay selection is considered to enhance the secrecy of a dual-hop regenerative multi-relay system with an eavesdropper. Without assuming perfect decoding at the relays, the secrec…
Secrecy Outage of Proactive Relay Selection by Eavesdropper
Sarbani Ghose, Chinmoy Kundu, Octavia A. Dobre
In this paper, we consider an active eavesdropping scenario in a cooperative system consisting of a source, a destination, and an active eavesdropper with multiple decode-and-forwa…
Effects of CSI Knowledge on Secrecy of Threshold-Selection Decode-and-Forward Relaying
Chinmoy Kundu, Sarbani Ghose, Telex M. N. Ngatched +3
This paper considers secrecy of a three node cooperative wireless system in the presence of a passive eavesdropper. The threshold-selection decode-and-forward (DF) relay is conside…
