Joint transmit power and physical carrier sensing adaptation based on loss differentiation for high density IEEE 802.11 WLAN
In high density (HD) IEEE 802.11 WLAN, packet loss can occur due to co-channel interference (asynchronous interference) or collisions (synchronous interference). In order to effec...
