Sinkhole Attack Detection based on Redundancy Mechanism in Wireless Sensor Networks

Wireless sensor networkshas a bright future because of its low-cost, save-power, and easy implementation .etc. However, its security problems have become hot research topics in many applications. Sinkhole attack is just one of frequently encountered security problems, which is easily combined with other attacks to cause more damage. In order to prevent sinkhole attack, we do some research on it, and one way to detect the sinkhole attack based on the redundancy mechanism is proposed in this paper. For the suspicious nodes, messages are sent to them through multi-paths. By evaluating the replied comprehensively, the attacked nodes are finally confirmed. Lastly, a simulation is performed to test the effectiveness of the method. And the simulation shows that the approach could work to some extent.
