ABSTRACT: Wireless sensor networks (WSNs) consist of a large number of sensor
nodes that monitor the environment and a few base stations that collect the
sensor readings. Individual sensor nodes are subject to compromised security
because they may be deployed in hostile environments and each sensor node
communicates wirelessly. An adversary can inject false reports into the networks
via compromised nodes. Furthermore, an adversary can create a wormhole by
directly linking two compromised nodes or using out-of-band channels. If these
two kinds of attacks occur simultaneously in a network, existing methods cannot
defend against them adequately. We thus propose a secure routing method for
detecting false report injections and wormhole attacks in wireless sensor
networks. The proposed method uses ACK messages for detecting wormholes and is
based on a statistical en-route filtering (SEF) scheme for detecting false
reports. Simulation results show that the proposed method reduces energy
consumption by up to 20% and provide greater network security.
