Adaptive power control of localized subnets for reducing self-interference in wireless networks

One method to reduce self-interference in a wireless network, such as a Link 16 network, while maintaining simultaneous multiple access, takes advantage of the physical proximity of nodes in a localized subnetwork, such as a fighter-to-fighter subnetwork on a flight wing. , by actively reducing the transmission powers used for subnet messages between nodes. Calibration messages, such as Precise Participant Location and Identification (PPLI) messages, are exchanged between all nodes in the localized subnetwork, from which each node determines identities, transmission powers, noise levels and the SNRs of all other nodes. The node then determines a link margin for other nodes and sets its transmission power to a "safe" level for the subnetwork according to the lowest link margin.
