    Anomaly Detection in Wireless Sensor Networks Using Self-Organizing Map and Wavelets

    This paper proposes an anomaly detection scheme which is able to detect anomalies accurately by employing only important features of data signals, instead of using all the sensor data traces. The contribution of this paper centers on anomaly detection by using Discrete Wavelet Transform (DWT) combined with a competitive learning...

    Relative Gain Array Interaction Analysis of UPFC Device for Damping Oscillations

    UPFC devices are used to improve real power, reactive power, improve bus voltage and eliminate line loses in ac systems. An additional task of UPFC is to enhance transmission capacity as result of power oscillation damping. This paper use Relative Gain Array (RGA) for analyzing the interactions among the UPFC...

    Improved and Simple Scheduling Scheme for Real-Time Data Communication in Wireless Sensor Networks

    Data communication protocols in wireless sensor networks are influenced by the packet scheduling algorithm and the routing protocol. The packet scheduling algorithms can arbitrate the use of the network in a deadline sensitive manner to ensure that most packets make their deadline. The routing protocol can influence the paths taken...
