A Centralized Feedback Control Model for Resource Management in Wireless Networks

In a wireless environment, guaranteeing QoS constraints is challenging because applications at multiple devices share the same limited radio bandwidth in the network. In this paper we introduce and study a resource management model for centralized wireless networks, using feedback control theory. Before applying in practice, the proposed model is evaluated using the well-known 20-sim dynamic system simulator. The experimental results show that flexible and efficient resource allocation can be achieved under our specified system parameters and WLAN scenarios; however, care should be taken in setting the control parameters and coefficients.
