We investigate the problem of efficient resource control for elastic traffic over the EDCA (Enhanced Distributed Channel Access) and HCCA (Hybrid Coordination Function - HCF - Controlled Channel Access) mechanisms of IEEE 802.11e. Our approach consi
This paper presents a novel scheduling algorithm for HCCA (Hybrid Coordination Controlled Channel Access) access model of IEEE 802.11e.The aim of this algorithm is to enhance the QoS for the support the multimedia traffic. Compared with the schedule
转载关于WIFI 2.4G上20_40MHz带宽的一篇文章； Abstract—We investigate the impact of 20/40 MHz coexistence on the performance of wireless local area networks(WLANs). To that end, we present simulation results of overlapping basic service sets (BSSs), a 802.11n BSS
Three different MCS feedback mechanisms are defined: – Immediate: A station sends a request for MCS feedback and receives response from the MFB responder within the same scheduling interval („tranmission opportunity“, TXOP) – Delayed: A station send
