“…It causes the degradation of the total throughput of all terminals (utilization efficiency for the bandwidth). To improve the total throughput of terminals by avoiding data frame collisions, a novel MAC method, Synchronized Phase MAC (SP-MAC) [17]- [19], based on the synchronization phenomena of coupled oscillators [20] has been proposed. [17]- [19] have showed that SP-MAC can improve the total throughput by reducing data frame collisions drastically.…”

“…Moreover, there is a possibility that the AP occurs buffer overflow by many data arrived from each link. Here, from the characteristic of SP-MAC, each of the wireless terminals obtains the same transmission opportunity as the AP [17]. In other word, the AP has only the same channel resource as one of the wireless terminals.…”

Ryoma ANDO†a) , Student Member, Ryo HAMAMOTO † * b) , Hiroyasu OBATA †c) , Chisa TAKANO †d) , and Kenji ISHIDA †e) , Members SUMMARY In IEEE802.11 Wireless Local Area Networks (WLANs), frame collisions occur drastically when the number of wireless terminals connecting to the same Access Point (AP) increases. It causes the decrease of the total throughput of all terminals. To solve this issue, the authors have proposed a new media access control (MAC) method, Synchronized Phase MAC (SP-MAC), based on the synchronization phenomena of coupled oscillators. We have addressed the network environment in which only uplink flows from the wireless terminal to an AP exist. However, it is necessary to take into consideration of the real network environment in which uplink and downlink flows are generated simultaneously. If many bidirectional data flows exist in the WLAN, the AP receives many frames from both uplink and downlink by collision avoidance of SP-MAC. As a result, the total throughput decreases by buffer overflow in the AP. In this paper, we propose a priority control method based on SP-MAC for avoiding the buffer overflow in the AP under the bidirectional environment. Also, we show that the proposed method has an effect for improving buffer overflow in the AP and total throughput by the simulation.
