The authors propose two advancements in the existing Bloom filter based traceback schemes for WSNs (Wireless Sensor Networks): the support of directed queries, and a way of reducing the false positive rate at the nodes nearer to the sink. Simulation results show that the proposed mechanism can efficiently traceback the packets with very few false positives. Traceback in communication networks, is a promising solution to counter the spoofed attacks by determining the probable source of the malicious packet(s) or the attack path(s). Traceback schemes are very well addressed in the literature; however, most of the schemes are proposed for IP networks and very limited work can be seen in the field of WSN (Wireless Sensor Network) traceback.
