چکیده
We explore the influence of cooperative jamming on covert communication for integrated satellite–terrestrial relay networks (ISTRN) in this article, where one full-duplex is utilized to support communications and acts as a jammer confuse eavesdroppers. A scheme first proposed efficiently achieve specific scenario. Further, probability detection error (PDE) derived. Subsequently, minimum PDE calculated using optimal threshold. Moreover, closed-form expression outage (OP) acquired quantify system’s performance. Based this, we design power optimization algorithm enhance effective rate under covertness constraints. Lastly, numerical simulation results are given verify efficiency our when interrupting Notably, an allocation factor can be obtained, leading higher rate.

متن کاملCovert Communication Achieved by A Greedy Relay in Wireless Networks
Covert communication aims to hide the very existence of wireless transmissions in order to guarantee a strong security in wireless networks. In this work, we examine the possibility and achievable performance of covert communication in one-way relay networks. Specifically, the relay is greedy and opportunistically transmits its own information to the destination covertly on top of forwarding th...
متن کاملJamming in wireless networks with cooperative jammers
The problem of jamming plays a very important role in ensuring the quality and security of wireless communications, especially now when wireless networks are quickly becoming ubiquitous. Since jamming phenomenon can be considered as a game where a player (say, jammer) is playing against a user (transmitter), game theory is an appropriate tool for dealing with the jamming problem. In this paper ...

In cooperative communication systems, different terminals collaborate to form a virtual-multiple antenna array system and exploit the spatial diversity to achieve a better performance. It can be generally categorized into amplify-andforward protocol and decode and-forward protocol. Among the various cooperative communication protocols which have been proposed in the past decades, the slotted co...
متن کاملRelay Selection Considering Successive Packets Transmission in Cooperative Communication Networks
Relay selection has been regarded as an effective method to improve the performance of cooperative communication system. However, frequent operation of relay selection can bring enormous control message overhead and thereby decrease the performance of cooperative communication. To reduce the relay selection frequency, in this paper, we propose a relay selection scheme to choose the best relay w...
