A Trusted Ad Hoc Routing Protocol Based on Fuzzy Mathematics

Prior secure routing protocols in ad hoc networks are vulnerable under many kinds of attacks, such as wormhole attack, vertex cut attack, etc. Direct anonymous ad hoc on demand vector (DAAODV) protocol uses Direct anonymous attestation (DAA) protocol and Property based attestation (PBA) protocol to solve this problem, but its efficiency is relatively low. We propose a routing protocol called FuzzyAODV, which uses Trusted Computing technology to ensure routing security, while simplifies the secure link establishment. We also take malicious nodes into consideration, and propose a method to identify possible DoS attacks, thus adopt different strategies accordingly to keep high performance. We evaluate the performance of our protocol using NS2 network simulator, and the result shows that our protocol is more efficient than DAAODV protocol. Security analysis demonstrates the correctness of our solution.
