Network control platform (NCP) and quality of service switch (QSS) are developed to realize centralized control and management technology, which is essential for guaranteeing traffic engineering and service quality in the next generation network. This paper presents high-speed connection management mechanism to enhance connection setup delay of the existing SNMP interface between NCP and QSS. We built up a connection management platform in the laboratory environment to validate the realization of the proposed mechanism.
Home appliance load disaggregation using cepstrum-smoothing-based method
Kong, Seongbae,Kim, Youngwook,Ko, Rakkyung,Joo, Sung-Kwan IEEE 2015 IEEE transactions on consumer electronics Vol.61 No.1
<P>Various load disaggregation methods have been developed for monitoring home appliance loads to save energy in a smart home. Most of load disaggregation methods are designed to focus on the on/off events of single appliance. In reality, however, multiple appliances can be turned on/off simultaneously. Load disaggregation can be complicated by the simultaneous on/off events of multiple appliances. This paper presents a cepstrum-smoothing-based load disaggregation method to effectively deal with the simultaneous on/off events of multiple appliances. Further, a data acquisition system is developed to obtain only the characteristic signals of appliances and to filter the noise inputted from the power supply. Test results are provided to demonstrate the effectiveness of the proposed cepstrumsmoothing- based load disaggregation method<SUP>1</SUP>.</P>
