Abstract:In conventional slotted nonpersistent CSMA, a packet is generated during a slot, and the terminal senses the channel at the beginning of the next slot. It is known that slotted CSMA has better throughput performance than unslotted CSMA. However, because of the propagation delay, if more than two packets are generated during the same slot, later packets might sense the channel as idle, and they will cause a conflict. Furthermore, when the CSMA modes are used in practical radio communication systems, the hidden‐… 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.
