Robots searching for enemy sensor network

dez-song's picture

How to enable a robot to efficiently detect an enemy sensor network? This project develops algorithms and systems that enable a robot equipped with a directional radio antenna to detect transient and anonymous radio sources. The problem is difficult because the robot cannot treat the radio sources as continuous radio beacons due to unknown number of radio sources, signal source anonymity, short transmission durations, and dynamic/intermittent transmission patterns.

  • If we know the sensors employ CSMA MAC layer, we can use the information.

  • If we do not know anything but signal strength and antenna configuration, we have a different approach,
