Jamming Power Estimation Technique Under Wireless Physical Layer Security in Presence of an Eavesdropper

In this paper, we study the secrecy performance of a communication scenario between a transmitter and a receiver nodes in the presence of a passive eavesdropper node. In order to degrade the eavesdropper capacity, a friendly jammer node is employed to generate jamming signal. The jamming signal interferes and confuses the eavesdropper node. This paper proposes a jamming power estimation technique to achieve secrecy performance requirements. In this paper, we utilize the relation between the jamming power and the probability of secrecy outage to derive a closed form expression of the jamming power estimation technique. Based on the results, the proposed estimation technique meets the secrecy performance requirements.
