combined and analyzed. As the information is collected from different layers for detecting intru-
sion, therefore, the proposed architecture provides more accurate detection. Authors have claimed
that their proposed cross layer–based IDS is efcient in detecting multi-layer internal attacks. Also
the proposed cross layer–based IDS can detect low-intensity attacks and attack-switching behavior.
Chiang and Hu [20] have proposed a cross layer–based jamming detection system for wireless
broadcast networks. The proposed system initially works by building an asymmetric system using
a spread-spe ...
