Abstract: This study introduces an enhanced version of the PEGASIS algorithm, termed the improved energy efficient anytime optimistic (IEE AO) protocol, designed to improve energy efficiency in ...

Abstract: In this paper, we consider a stacked intelligent metasurface (SIM) with the ability to perform beamforming in the electromagnetic (EM) wave domain. We develop a path-loss model that allows ...

Abstract: As a kind of wavefront with helical phase, orbital angular momentum (OAM) shows the great potential to enhance the security results of wireless communications due to its unique orthogonality ...

Abstract: In covert communications, the position of the warden has a variety of situations, which leads to different scenes that require different covert communication schemes to ensure the security.

Abstract: Reconfigurable intelligent surface (RIS) has emerged as a cost-effective solution for green communications in 6G. However, its further extensive use has been greatly limited due to its fully ...

Abstract: This study investigates the design of an integrated sensing and communication (ISAC) system under conditions of imperfect channel state information (CSI). It leverages rate-splitting ...

Abstract: In this paper, we study an intelligent reflecting surface (IRS)-aided radar-communication (Radcom) system, where the IRS is leveraged to help Radcom base station (BS) transmit the joint of ...

Abstract: This work investigates secure transmission in non-orthogonal multiple access (NOMA)-integrated sensing and communication (ISAC) systems, where legitimate users may act as internal ...

Abstract: Simultaneously transmitting and reflecting reconfigurable intelligent surface (STAR-RIS) has attracted considerable attention due to its ability to overcome the half-space limitation of ...
