| 摘 要： | 定向扩散路由协议极易遭受虫洞攻击。为此，以仅存在2个毒害节点的情况为例，推导毒害节点放置位置与虫洞攻击严重程度间的定量关系。通过OMNeT++上的仿真实验，求解毒害节点最佳放置位置，并说明对应的最大虫洞攻击严重程度。为预防虫洞攻击，提出一种将最佳梯度节点加强转换为梯度节点概率选择加强的策略。仿真实验结果表明，该预防策略是有效的。

| Abstract: | 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 |
