Abstract: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 jamme… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
