A Novel Traceback Scheme of Malicious Nodes in Wireless Sensor Networks
Xin Wang · Chuangan jishu xuebao · 2013
For wireless sensor networks lacking of single reliable routing device,the packet markings will be tampered by forwarding nodes.In order to solve this problem,this paper proposes an improved node sampling packet marking method.The method generates the watermark with the ID and data packet by hash function,and then probabilistic watermark marking(PWM)marks into the marked area.The Sink node can trace the malicious node using the markings.This algorithm effectively prevents the colluded nodes from changing marking,and locates the malicious node in a hop.The theoretical analysis and simulations show that the improved algorithm can effectively track the malicious nodes.Compared to the methods of based on edge marking traceback,the success rate rapidly increases.
