摘要: In this paper we propose an enhanced Transmit Power Control (TPC) scheme and a new fractional Carrier Sense Multiple Access with Collision A voidance (F-CSMA/CA) for use in dense 802.11 network. The schemes improve the energy normalized Media Goodput performance networks overlapping Basic Service Sets (OBSSs) by mitigating interference effect using TPC reducing generated during neighboring BSS-edge transmission inter-cell coordination. works seamlessly CSMA/CA multiple access technique, is suitable evolution of future WLAN systems such as IEEE 802.11ah [4], High Efficiency WiFi (HEW) [5]. Numerical results demonstrate increase good put up to 80% downlink 100% uplink over existing schemes.
