Abstract

A method is provided that can include designating as a control node, a first communication node of a plurality of communication nodes associated with a satellite communications system. The method can include, designating as a listening node, a second communication node of the plurality of communication nodes. The listening node is responsive to instructions provided by the control node. The method includes receiving, at a tuning module, one or more input tuning factors, wherein the one or more input tuning factors can include at least a resource burden factor. Responsive to receiving the one or more input tuning factors, the method includes adjusting by the tuning module, one or more tunable output parameters. The method includes sending, from the control node to the listening node, instructions comprising one or more of the tunable output parameters, and executing the instructions at the listening node.
