The correspondence highlights the potential of reconfigurable intelligent surface (RIS) in anti-jamming communications, focusing on an aerial RIS (ARIS) deployed in the air to mitigate jamming attacks and enhance legitimate transmissions. Through joint optimization of ARIS deployment and passive beamforming, the problem is solved using an alternating optimization framework, with simulation results demonstrating the effectiveness of ARIS in mitigating jamming attacks.
This correspondence reveals the potential of reconfigurable intelligent surface (RIS) in anti-jamming communications. In particular, we consider an aerial RIS (ARIS) that can be flexibly deployed in the air so as to mitigate jamming attacks and enhance the legitimate transmissions. We formulate the joint optimization of ARIS deployment and passive beamforming and solve the problem through an alternating optimization framework, where the location of ARIS is obtained by successive convex approximation and the reflection beamformer is tackled with manifold optimization. Finally, simulation results demonstrate that an ARIS with our proposal can effectively mitigate the jamming attacks and thus safeguard the legitimate transmissions.
