Variants of Wormhole Attacks and Their Impact in Wireless Sensor Networks

摘要

In wireless sensor networks, nodes have limited battery, transmission power, and processing capabilities. For routing the packets, cooperation between nodes is needed. Wireless sensor network is vulnerable to wide range of attacks. A more dangerous attack is wormhole attack in which packets are received in one area and replied in another area of the network. For on-demand routing protocols, route discovery mechanism is affected by wormhole attack and routing is disturbed. In this paper, we have presented variants of wormhole attacks and their impact in wireless sensor networks.
