Identify Abnormal Packet Loss in Selective Forwarding Attacks
Gao Chuan · Chinese Journal of Computers · 2006
In this paper,the authors propose a lightweight security scheme,CHEMAS(CHEckpoint-based Multi-hop Acknowledgement Scheme),for detecting selective forwarding attacks.This scheme can randomly select part of intermediate nodes along a forwarding path as checkpoint nodes which are responsible for generating acknowledgements for each packet received.The strategy of random checkpoint selection significantly increases the resilience against attacks because it prevents a proportion of the sensor nodes from becoming the targets of attempts to compromise them.The authors examine the detection accuracy of this scheme using both theoretical analysis and simulations.
