Directed Diffusion Routing Protocol(DDRP) is easy to suffer from wormhole attack.Take only two wormhole nodes in Wireless Sensor Network(WSN) for example,the quantitative relationship between placement of poison nodes and severity of wormhole attack is formulated reduction.The optimal placement of two poison nodes and most severity of wormhole attack are solved by simulation on OMNeT++ platform.In order to prevent wormhole attack,the best gradient node reinforcement is changed into gradient nodes probabilistic selected reinforcement in DDRP.Simulation results prove the effectiveness of the proposed strategy
