摘要：
Cooperative jamming, a potential supplement can be used to improve physical layer based security by transmitting a weighted jamming signal to create interference at the eavesdropper. The secrecy rate is derived for cooperative jamming technique in terms of network throughput. We have analysed the effect of Aloha protocol with cooperative jamming on the secrecy capacity of large scale network. To implement cooperative jamming with Aloha protocol a transmitter can be considered as a source or as a friendly jammer with the massage transmission probability p. We observed that an optimum level of security can be achieved for a specific value of jammer power using cooperative jamming and at the moderate value of massage transmission probability p using cooperative jamming with Aloha protocol.
