Abstract:
1. In an ad-hoc network, a method of detecting messages from an unwanted intruder, the method comprising: receiving a first message purporting to be from a mobile communication device in the ad-hoc network, the first message having a first location component incorporated therein; receiving a second message purporting to be from the mobile communication device, the second message having a second location component incorporated therein; determining movement based upon the first location component and the second location component; and determining whether at least one of the first message and the second message is from the intruder by comparing the movement with a distance required for the mobile communication device to change direction, wherein the distance required for the mobile communication device to change direction is determined based on physical movement capabilities of a vehicle or person with which the mobile communication device is associated and the distance required for the mobile communication device to change direction is stored in a database, and wherein determining whether at least one of the first message and the second message is from the intruder comprises determining that at least one of the first message and the second message is from the intruder when the movement and the distance required for the mobile communication device to change direction indicate that the mobile communication device could not have changed direction quickly enough to travel from a location associated with the first location component to a location associated with the second location component.
