摘要：In wireless networks, security issues have taken acritical role in today’s communications. In the proposed work,two hop wireless relay network in the presence of aneavesdropper is considered. The interest spans over a fournode network model including a source, destination, trustedrelay and an untrusted eavesdropper, in which the relayforwards the source message in a decode-and forward manner.When transmitting the messages from source to relay,eavesdropper intercept and try to capture that messages. Thedestination transmits an artificial jamming noise to the relay,to prevent that eavesdropper interception. This approach isanalyzed for different jamming power allocation schemes tominimize the outage probability of the secrecy rate andimprove the SNR rate, based on the channel state informationavailable at the destination.
