Extending probabilistic packet marking algorithm to detect DDoS in WSN

Traditional probabilistic packet marking algorithm can not fit to detect DDoS in wireless sensor networks (WSNs), because WSNs have resource constraints. A DDoS attack may result in network disasters due to the energy exhaustion of the nodes along the attacking path. This paper presented a new extended probabilistic packet marking algorithm to detect DDoS in WSNs which enabled to reconstruct attacking paths with fewer collected packets under multiple attacks. The effectiveness of the proposed algorithm was demonstrated in the simulate studies.
