An Efficient Cross-Layer Approach for Malicious Packet Dropping Detection in MANETs

This paper introduces a novel IDS approach for detecting malicious packet dropping behaviors in MANETs. Although some similar proposals can be found in the specialized literature, two main differences exist with ours. First, mobility aspects are explicitly considered into the approach by means of a heuristic which considers the operation of the forwarding process at the nodes. Second, this fact results in a significant improvement in the detection performance of the system, especially in terms of low false positive rate. The different experimental results obtained show the promising nature of our approach, both in terms of the detection capabilities exhibited and from the point of view of the simplicity of the scheme.
