MSOM: Efficient Mechanism for Defense against DDoS Attacks in VANET

Algorithm 1

Multilayer Distributed SOM.

1 while(True) do

2Randomly initialize DSOM weights

3Sequentially input data from initial dataset

4while (criterion DSOM) do

5Compute the Euclidean distance betweenand

6Update the weights of the winning neuron and its neighborhood of BMU

7Input into CSOM

8Compute the Pearson squared distance betweenandwith

9Start training

10Merge DSOMs sent from all RSCs to eNBC

11Distribute the merged map (DSOM) to all RSCs

12Classify incoming traffic as normal or attack
