Receiver Centric Physical Carrier Sensing for Vehicular Ad Hoc Networks
Joon Yoo · 2013
Most vehicular ad hoc networks use sender-centric carrier sensing where a sender determines the transmission timing through channel assessment. However, sender-centric carrier sensing suffers from both exposed and hidden terminal problems even with physical and virtual carrier sensing. In this paper, we propose a new receiver-centric carrier sense (RCS) technique where a receiver triggers packet transmissions based on local channel assessment.
