Abstract:Abstract-In this paper, we propose a simple and standard compliant retransmission mechanism, called Carrier-Sense Automatic Repeat reQuest (CS-ARQ), which aims at improving system performance, both in terms of throughput and energy efficiency, by avoiding useless data packet retransmissions. More specifically, in case of missed acknowledgment (ACK), the source makes use of its carrier-sensing capabilities to decide whether retransmitting the data packet or soliciting the ACK retransmission from the destination… 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.
