A Software-Defined Networking (SDN) agent is a software element bridging an SDN controller and any legacy wireless network elements by providing the abstraction of these elements. In this paper, we present the work of an SDN approach for designing and implementing a radio resource management (RRM) framework for wireless local area networks (WLAN). The framework provides support for real-time rate adaptation (RA) and transmit power control (TPC) applications. It is also flexible to satisfy various degrees of granularity, per link, per flow and per packet. We implement the proposed framework as an extension to the Wireless Open-Access Research Platform (WARP), an FPGA based Software-Defined Radio (SDR) platform. Our evaluation results demonstrate the effectiveness of decoupling RRM functions from the underlying wireless hardware. To highlight the applicability of our approach, we present a use case deployed over the framework focusing on providing high-throughput reliable multicast transmissions, hence improving the WLAN's overall spectrum efficiency.
