Defending Selective Forwarding Attacks in Underwater Acoustic Networks Applying Trust Model

Underwater Acoustic Networks (UAN) are formed by acoustically connected ocean-bottom sensors, autonomous vehicles that function underwater in tandem with a surface station to provide a link to an on-shore control center. Applications that deploy them require long-term monitoring of the deployment area. The safety and security of such networks should be guaranteed in the light of Denial of Service (DoS) attack a class of attack that commonly targets them. A specific kind of DoS attack termed as selective forwarding is considered and an improved solution to defend such attack is proposed and analyzed for its efficiency.
