In this paper, we introduce the concept of ceased areas for enhancing the spatial reuse in CSMA/CA based wireless ad hoc networks. Intuitively, a ceased area is created by a transmitter-receiver pair where all other nodes are required to keep silent. The size of a ceased area depends on the transmission power and the transmitter-receiver distance. A new transmission power control (TPC) scheme that can minimize the induced ceased area is proposed. And it is superior to previous TPC schemes in throughput.
In this paper, based on the concept of ceased areas, the spatial reuse in IEEE 802.11 ad hoc networks is enhanced by transmission power control (TPC). A ceased area is created by a transmitter-receiver pair where all other nodes should cease their transmissions for a while. The size of a ceased area varies with the transmission power. A new TPC scheme that can minimize the induced ceased area is proposed. It is practical without needs to know the transmitter-receiver distance. And its performance in network throughput is superior to previous TPC schemes.
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.
