A dual constraint based wormhole attack detection method is proposed to address the most destructive wormhole attacks in wireless sensor networks.This algorithm improves the Shadowing path loss model and RSSI ranging technology by limiting the transmission distance of neighbor discovery messages to prevent wormhole nodes from establishing false neighbors.It also uses an encrypted hash key algorithm to determine the legitimacy of data during transmission,preventing internal wormhole attacks during the data transmission phase.If abnormal data is found,the energy threshold constraint principle is used to detect wormhole attack nodes and delete them,effectively solving the problems of data loss and tampering caused by wormhole attacks.The simulation results based on OMNeT++show that the algorithm outperforms other algorithms in terms of malicious node detection rate,error rate,and network lifecycle,and can effectively prevent wormhole attacks in wireless sensor networks.
