In this paper, we propose an enhancement to the existing IEEE 802.11 DCF MAC function to improve channel spatial reuse efficiency, and thus improve data throughput. Our modification, named the Location Enhanced DCF (LED) for IEEE 802.11, incorporates location information in the RTS-CTS-Data-ACK handshakes of the IEEE 802.11 DCF so that other stations sharing the channel are able to make better interference predictions and blocking assessments. Physical layer receiver capture effect is also useddoi:10.1109/infcom.2005.1497931 dblp:conf/infocom/NadeemJAA05 fatcat:t6jdojlm4re6lkxgh7rkwiokte
