A Multivariant Stream Analysis Approach to Detect and Mitigate DDoS Attacks in Vehicular Ad Hoc Networks

Algorithm 3

Input: Network Trace Nt.

Output: Null.

Step 1. Start

Step 2. Read Network Trace Nt.

Step 3. Rule set Rs = Preprocessing(Nt)

Step 4. Receive incoming packet .

Step 5. Compute multi-attribute stream weight MASW.

Step 6. For each rule Ri from Rule set Rs

Step 7. Compute similarity measure MASM =

Step 8. If MASM < MASW && MASM<>Ri.Features

Step 9. Classify True

Step 10. Else

Step 11. Classify malicious

Step 12. End

Step 13. End

Step 14. Stop.
