1. A method for detecting malicious data in an ad-hoc network, comprising:

  • receiving data at a node in the ad-hoc network, the data having purportedly been sensed by other nodes in the ad-hoc network,wherein a given node senses data associated with itself and with proximate nodes in the ad-hoc network, whereby proximate nodes in the ad-hoc network can redundantly sense data about each other,wherein the received data was redundantly communicated to the node by the other nodes in the ad-hoc network;

    determining, at the node, if the received data, along with data sensed locally by the node, is consistent; and

    if not, using a model which accounts for malicious nodes to determine an explanation for the inconsistency.
