“…A new wireless network technology IEEE802.11ax being developed, the use of this technology can achieve 8 seconds to download complete 10GB of capacity. [6] IEEE802.ax not only use the MU-MIMO (Multi-User Multiple-Input MultipleOutput) technology, but also the use of OFDMA (Orthogonal Frequency Division Multiple Access), that is orthogonal frequency-division multiple access technology, which is the next-generation high-speed wireless. Therefore, the "Internet + MOOC" mode is Internet-based, with 2G, 3G, 4G and WLAN, WIFI wireless network communications technology.…”

Abstract. This paper is devoted to examining the construction of MOOC platform based "Internet +". It firstly introduced the "Internet+" model, the "Internet + education" influence and the significance of education. Then, it analyzed the existing problems in the development of the current MOOC, and put forward the model of "Internet + MOOC" through the method of software engineering. It explored the advantage of "Internet + MOOC" mode and promoting the function to the education teaching. This paper put forward the framework of "Internet + MOOC platform model, and point out the problems need attention in the construction of the platform.

Abstract-Age of Information (AoI) is a relatively new metric introduced to capture the freshness of a particular piece of information. While throughput and delay measurements are widely studied in the context of dense IEEE 802.11 Wireless LANs (WLANs), little is known in the literature about the AoI in this context. In this work we study the effects on the average AoI and its variance when a sensor node is immersed in a dense IEEE 802.11 WLAN. We also introduce a new cross layer MAC technique, called Latest UPdate MAC (LUPMAC), aimed at modifying the existing IEEE 802.11 in order to minimize the average AoI at the receiver end. This technique lets the MAC layer keep only the most up to date packets of a particular piece of information in the buffer. We show, through simulation, that this technique achieves significant advantages in the case of a congested dense IEEE 802.11 WLAN, and it is resilient to changes in the variance of the total network delay.

“…The IEEE standard for WLANs was named as IEEE 802.4L at the beginning in 1988, while it was renamed as IEEE 802.11 in 1990 [1]. IEEE 802.11 standard defined the physical layer (PHY) and medium access control sub-layer (MAC) specification for the WLANs [2].…”
