Identifying network failure via detecting changes in power profile

Failure in the network devices can be identified by detecting changes in the behaviour of the network. Such a network can be part of the communication infrastructure, which will play a significant role in the emergency managements. Network power consumption behaviour, namely its power profile, is a relatively robust profile such that from changes in that profile failure of the links or/and the nodes in the network can be detected. In this paper, we propose a statistical change detection system that relies on the Intersection of Confidence Intervals (ICI)-based test to detect variations in the profile of the power consumption. After failure detection, the proposed solution continues reading new samples of power consumption data to build the new power profile, which will allow us to detect multiple failures that occur in series. Through numerical examinations we show the effectiveness of the change detection action.
