DETECTING WORMHOLE ATTACKS IN WIRELESS SENSOR NETWORKS
Keywords:WSN, wormhole, security attacks, defense mechanism, special network,malicious node, sensor nodes, string topology, anchor node, directional antenna.
Wireless sensor networks (WSN), consisting of wireless sensors and control devices and methods of self-organization using intelligent algorithms, demonstrate broad prospects. WSNs are subject to numerous types of threats and attacks. One of which is a wormhole attack. This article provides an overview of wormhole attack detection methods in WSN, as well as a new optimized method for detecting this attack. The detection method is based on the removal of the edges of the wormhole and causes significant changes in the length of the shortest paths between network nodes.The accuracy of the proposed algorithm is not affected by the number of wormholes
