Dynamic Radio Resource Management, RRM, is an essential design block in the functional architecture of any Wifi controller in IEEE 802.11 indoor dense enterprise Wlans.

In a mono-channel condition, it helps tackle co-channel interference problem and enrich end-to-end Wifi clients experience.

In this work, we present our dRRM solution: WLCx, and demonstrate its performance over related-work and vendor approaches.

Our solution is built on a novel and realistic per-Beam coverage representation approach.

Unlike the other RRM solutions, WLCx is dynamic: even the calculation system parameters are processed. This processing comes at price in terms of processing time.

To overcome this limitation, we constructed and implemented a NURBS surface-based optimization to our RRM solution. Our NURBS optimized WLCx, N-WLCx, solution achieves almost 92.58% time reduction in comparison with basic WLCx. Furthermore, our optimization could easily be extended to enhance others, vendors and research, RRM solutions.
