Analysis of Wormhole Attack on Network Based on RPL

Abstract

Due to the growth of Internet literacy, the current world is transforming in a rapid way. The emergence of IoT has an important part to play in this growth. As the devices started to get smart, a new concept was introduced, where objects and things could communicate with each other and was named Internet of Things. The growth was so rapid that the security aspects could not keep up with the technology. Security in IoT devices is one of the biggest concerns while implementing these devices. IoT devices work with constrain resources under constrain environments. To overcome such challenges, routing over low power and lossy network (RPL) was introduced. RPL uses distance vector routing protocol to deliver data/packets from one destination to other. RPL works with 6LoWPAN which stands for IPv6 over low-power wireless personal area networks. The two combined make IoT protocol for routing over low power and lossy network, but these protocols do not provide any security to the IoT network. The main motivation of this paper is to observe the network behavior for RPL by simulating a wormhole attack. As wormhole attack is one of the most significant attack in wireless sensor network, the paper focuses on the power consumption of a normal RPL network and comparing it with the network preforming the wormhole attack. The wormhole attack is mostly used for misguiding packets and creating a false path for the packets to take while disrupting the network behavior. The observation between the two networks is presented in this paper. The
