This paper presents the design, implementation, and experimental evaluation of CMAP (Conflict MAPs), a system that increases the number of successful concurrent transmissions in a wireless network, achieving higher aggregate throughput compared to networks that use Carrier Sense Multiple Access (CSMA). CMAP correctly identifies and exploits exposed terminals in which two senders are within range of one another, but each intended receiver is far enough from the other sender that the two transmissions can succeed even if done concurrently.
