In Wireless Sensor Network (WSN), securable data transmission is one of the most challenges. During the transmission between the source and a destination node, routing information of the particular path may be misbehaved by the particular nodes which are known as wormhole nodes/attackers. The paths which include the wormhole nodes are known as wormhole attacked paths. For improving security in WSN, these wormhole attacked paths should be identified. To achieve this, wormhole attack detection method and optimal or secure path selection are presented in this paper. Initially, ‘K’ paths or multiple paths are generated between source and destination using Ad-hoc On demand Multipath Distance Vector (AOMDV) routing protocol. Then, the source node identifies the wormhole attacked path by verifying the Detection Packet (DP) and Feedback Packet (FP) from the destination. After detecting the wormhole attacked paths, the source node selects the optimal path among the attacker free paths using Particle Swarm Optimization (PSO) algorithm. Simulation results show that the performance of the proposed approach improves energy efficiency and network lifetime of the network.

在无线传感器网络（WSN）中，安全的数据传输是最大的挑战之一。在源节点和目标节点之间的传输过程中，特定路径的路由信息​​可能会被称为虫洞节点/攻击者的特定节点误导。包括虫洞节点的路径被称为虫洞攻击路径。为了提高WSN的安全性，应确定这些虫洞攻击路径。为此，本文提出了虫洞攻击检测方法以及最优或安全的路径选择方法。最初，使用临时按需多路径距离矢量（AOMDV）路由协议在源和目标之间生成“ K”个路径或多个路径。然后，源节点通过验证来自目标的检测数据包（DP）和反馈数据包（FP）来标识蠕虫攻击路径。在检测到虫洞攻击路径后，源节点使用粒子群优化（PSO）算法在攻击者自由路径中选择最佳路径。仿真结果表明，所提方法的性能提高了网络的能效和网络寿命。
