Sketch Based Anomaly Detection Scheme in Wireless Sensor Networks

The constrained capacity of wireless sensor nodes and harsh, unattended deploy environments make the data collected by sensor nodes usually unreliable. We have proposed a count-min sketch based anomaly detection scheme with the goal of detecting the ...

This article describes a distributed hyperspherical cluster based algorithm for identifying anomalies in measurements from a wireless sensor network, and an implementation on a real wireless sensor network testbed. The communication overhead incurred in ...

In the Internet of Things era, Wireless Sensor Network (WSN) acts as a key infrastructure, provides a large number of outstanding applications nowadays. WSN is a distributed and self-organizing wireless network with lots of constraint issues such as ...
