Abstract
A method for mitigating the effect of a localized jamming attack on a secure, tactical wireless network implements a dynamic relay assignment ('DRA') approach, whereby nodes are dynamically assigned to relay communications to 'disadvantaged' nodes that are subject to the attack, the relay nodes being selected based on their communication reliability and their proximity to the disadvantaged nodes. In embodiments, the nodes share with each other performance statistics and, in embodiments, measured local noise levels. In various embodiments, each node provides data to a “strategy optimizer” which then dynamically makes relay assignments. In Link-16 embodiments support for a “DRA” relay mode is added, and the communication protocol is extended to support the required exchange of communication quality and local noise information via PPLI messages.
