Title: Visual Detection of Anomalies in Wireless Sensor Networks

Speaker: Prof. Jim Bezdek

Time and Date: 2.00 pm, Tuesday, 23 March 2010

Place: Brown Theatre, Dept. of EEE (building 193), The University of Melbourne

Abstract:

This talk begins with some general information about wireless sensor networks (WSNs). We propose classification of WSN anomalies as: type 1 (at a single node); type  2 (an entire node); and higher order (a subtree of nodes in the network). We give definitions for three models of anomalies using level sets of ellipsoids. Then we define three measures of similarity on sets of ellipsoids. The similarities in turn enable us to apply visual assessment techniques (the VAT method) to images of the (dis)similarity data so derived. We conclude with two examples that show how elliptical anomalies might be detected in real WSNs.
