Ellipsoidal neighbourhood outlier factor for distributed anomaly detection in resource constrained networks

作者:

Highlights:

• Detecting anomalies in data is challenging on resource constrained networks.

• A hyperEllipsoidal Neighborhood Outlier Factor (ENOF) is proposed.

• A distributed algorithm using hypersellipsoidal clusters and ENOF scheme is proposed.

• Capable of identifying local and global anomalies at individual node levels.

• Achieves superior detection capabilities with minimal communication overhead.
