A kind of wormhole attack defense strategy of WSN based on neighbor nodes verification

摘要

Wormhole is a kind of attack in Wireless Sensor Network (WSN) that needs not to crack encryption key, which has great harm. Aiming at characteristics of Wormhole attack, the paper presented a kind of wormhole attack defense strategy of WSN based on neighbor nodes verification. Under this strategy, when each normal node received control packet, it will monitor the packet to determine whether it comes from its normal neighbor nodes to avoid Wormhole attack effectively. Modeling and simulation of WSN based on OMNeT++ shows that the AODV added neighbor nodes verification successfully implement effective defense.
