Abstract

As sensor-driven applications become progressively more integrated into our lives; issues linked to sensor privacy will become increasingly important. In wireless sensor networks, adversaries can make use of the traffic information for locating the monitored objects. Network coding has been shown to be an efficient approach to improve the wireless system performance. In a wormhole attack, the attacker can forward each packet using wormhole links and without modifies the packet transmission by routing it to an unauthorized remote node and pose a severe threat to many functions in the network, such as routing and localization. We developed a wormhole attack and are prevented by DAWN (Distributed detection Algorithm against Wormhole attack in wireless Network coding systems) algorithm using hash operation in cryptosystems. Simulation and methodical results reveal that our scheme acquires low energy consumption and less false positive rate than hotspot attack.
