Detailed Diagnosis of Performance Anomalies in Sensornets

Executive Summary

This paper addresses the problem of analysing performance anomalies in sensor networks. This paper proposes an approach that uses the local flash storage of the motes for logging system data, in combination with online statistical analysis. The results show not only that this is a feasible method but that the overhead is significantly lower than that of communication-centric methods, and that interesting patterns can be revealed when calculating the correlation of large data sets of separate event types.
