Detection and Prevention of Wormhole Attacks in Wireless Sensor Networks

Abstract

Abstract-A Wireless Sensor Network (WSN) is a collection of petite sensor terminals, capable of sensing and communication. Here topology is dynamic Node developments result in dynamic topology and cause link failures in an Ad-hoc. Here focusing on the using of packet scheduling technique for AODV (Ad Hoc on Demand Distance Vector) routing protocol by weight hop based scheduling in this paper. The transitional node starts the packet scheduling and manages its buffer memory according to data transfer rate. Intermediate store the data packets and repair the broken route and manage overflow of data packets. This proposed system attempt to send the data packet by utilizing backup routes opposed to dropping it. It evaluates the planned procedure on NS-2.34 simulator. Simulation results show that proposed scheme performance is better than AODV.
