Abstract
A method for optimizing a wireless network comprises obtaining local measurement and feedback data from a single node in the network; estimating a state of the node by using the local measurement and feedback data in an analysis framework model of the wireless network; applying the estimated state of the node to a local control law to determine one or more local protocol parameter updates for the node; and transmitting the one or more local protocol parameter updates to the node in the network. The method can further comprise obtaining global measurement and feedback data from one or more additional nodes in the network; estimating a state of the one or more additional nodes by using the global measurement and feedback data in the analysis framework model; applying the estimated state of the one or more additional nodes to the local control law; applying the estimated state of the one or more additional nodes to a global control law to determine one or more network-wide protocol parameter updates; and transmitting the network-wide protocol parameter updates to the network.
