Detection and Prevention of Wormhole Attacks in Leach Protocol for Wireless Sensor Networks

Authors : R.M. Dilip Charaan, R. Ramesh and E. Uma

Abstract: Due to the remote wireless nature and human unattended environment of WSN, they are more vulnerable to various types of attacks and intruders may visit these networks purposely or unintentionally. The algorithms proposed in order to detect if any intruder is inside the network and to detect the wormhole and black hole attacks. In this detection technique it tries to prevent the attacks in LEACH protocol in a wireless sensor networks using the multiple base stations and key. Since, LEACH protocol is used the consumption of energy is also reduced to maximum extent. This in turn reduces the overhead and data delivery increases. As multiple base stations are employed data gets delivered cent percent. Since, LEACH protocol is used, it guarantees power supply for a considerable amount of time with extra energy. This ensures that the packet delivery ratio has increased prolonging the lifetime of the network. The individual nodes are given more security, adding security to nodes will consume more energy thus reducing the lifetime of the network. If the nodes are solar aware, the energy level gets equalised and also surplus energy may be obtained because of usage of LEACH protocol. The proposed protocols are made to detect and prevent the attacks thus controlling the overhead, increasing packets delivered and extending the lifetime of the wireless sensor networks.
