Wormhole attack is a severe attack in mobile ad hoc networks, which is particularly challenging to defend against.In this paper, a new method defined as time ruler using distance measurement for detecting wormhole attack is proposed including its hypothetical model, the concept of time ruler and the process of its establishment, storage and calibration.The feasibility of the method on theory, thus respectively deriving two discriminating inequalities with the use of sending time ruler and receiving time ruler are analyzed in detail.The performances of the method are also analyzed and its validity is evaluated with Omnet++ developing tools.
