Dynamic Routing Under Extreme Cognitive Jamming Environments

摘要

A system and methods for dynamic routing under extreme cognitive jamming environments are presented. Jammer signals emitted by a network protocol-aware cognitive jammer are scanned for at a router node in an ad-hoc wireless network, and jammer behaviors are detected based on signal characteristics of the jammer signals. A network dynamic pattern caused by the network protocol-aware cognitive jammer is classified based on the detected jammer behaviors observed over a period of time, and dynamic routing strategies of the first router node are adapted to achieve robust data delivery based on the network behavioral pattern. Data packets sent by the router node are routed to avoid nodes and routes that are affected by the jammer signals.
