Abstract

Message In Message (MIM) is an emerging wireless technology to improve the capacity of wireless networks, which augments concurrent transmission opportunities of contending wireless nodes. In a MIM-capable communication system, however, the challenging problem is that the concurrent transmission opportunity is restricted by underlying network topologies. In this paper, we propose an MIM-aware association control scheme (MIMAC) that can greatly increase concurrent transmission opportunities by regulating the association among OpenFlow APs in NOX-based wireless systems. MIMAC exploits the distinctive features of NOX architectures, such as maintaining a global view of the network topology and controlling the association among OpenFlow APs in a centralized way. Using simulation-based evaluations, we demonstrate that MIMAC achieves high throughput enhancement by up to 200% compared to legacy WLAN systems.
