Wireless LAN based on IEEE802.11 standard uses Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) for media access control. However, the data frame collisions often occur if the number of wireless terminals increases in CSMA/CA. To solve this problem, the authors have already proposed and evaluated an media access control method based on synchronization of coupled oscillators (SP-MAC). Previous evaluations showed SP-MAC can obtain high total throughput of all wireless terminals compared to CSMA/CA in the specified environment. However, it is unclear the performance in other environments. This paper evaluates the SP-MAC performance considering the number of wireless terminals, several traffic patterns, and the applicability of SP-MAC for a real-time communication.
