LoRa is an unlicensed band-based low-power and wide-area (LPWA) technology, which has great network resource constraints because of its limited available frequency resource due to narrow industrial scientific medical (ISM) band, long response time due to its low data rate and low resource utilization due to its primitive medium access control (MAC). This paper studies […]

Recently, the IEEE 802.11 working group has announced a new distributed access mechanism called Enhanced DCF (EDCF) to provide service differentiation among traffic classes defined as access category. With the increasing demand for supporting Quality of Service (QoS) in IEEE 802.11 wireless LANs, the EDCF is now attracting many researchers’ attention due to its practical […]
