Efficient Detection of Routing Attacks in Wireless Sensor Networks

A lot of effort has been spent in securing the routing procedure in wireless sensor network (WSNs) since this is accomplished in a cooperative way and is vital for the communication of the sensors with the base station which collects the sensed data. The communication over wireless links in combination with the ad hoc organization introduces vulnerabilities. Each node monitors the behaviour of its neighbours in order to check whether they behave maliciously or not. Nodes with low trustworthiness are then avoided during routing decisions which are based on location and trust information. The efficiency of the proposed approach in defending against black-hole, grey-hole and integrity attacks is evaluated using computer simulations.
