Merit of PHY-MAC Cross-Layer Carrier Sensing: A MAC-Address-based Physical Carrier Sensing Scheme for Solving Hidden-Node and Ex
This paper examines how various carrier-sensing schemes affect the exposed-node (EN) and hidden-node (HN) phenomena. In the process, we identify a new carrier-sensing mechanism fo...
