Satellite communication networks have been considered an integral part of B5G and 6G
networks to achieve global coverage and enhanced Internet services. However, the …

In this paper, we investigate security and energy efficiency of multicast communication in
cognitive satellite terrestrial networks. To achieve high spectrum efficiency and low …

In this paper, we propose a dynamic spectrum allocation (DSA) scheme DeepBlocks at the
backdrop of sixth-generation (6G) communication networks that address the challenges of …

Cognitive radio (CR) technology allows secondary users (SUs) to opportunistically access
the licensed spectrum being authorized by the primary users (PUs) and then improves the …

This letter investigates the dynamic changes of security and efficiency in an unmanned
aerial vehicle (UAV)-to-ground network with a mobile UAV transmitter, a mobile ground …

Cooperative spectrum sensing among cognitive radio (CR) enabled smart devices improves
the sensing performance in deep fading environments. However, it is prone to attacks by …

This paper studies the possible physical layer security (PLS) enhancement in a wiretapped
two-way relay system from utilizing the reconfigurable intelligent surface (RIS) and …

Energy consumption remains an open challenge in aerial systems such as CubeSats and
therefore optimization of its allocation is a top priority for maximizing operational capacity …

In this paper, we have combined a game‐theoretic and an information‐theoretic notions to
describe the selfish behavior of each user in a two‐user linear deterministic cognitive …

In this paper, a two‐way relay‐aided cognitive satellite terrestrial network (TR‐CSTN) model
is proposed, where primary users are located at the edge of the base station. In the TR …
