In this paper we explore the possibility of inferring activities of daily life (ADLs) from aggregate power load signatures of people's homes, which has many applications including e-healthcare. Such power load data are available from smart meters that will be widely deployed in many countries by utilities or customers, creating an infrastructure at the forefront of the Internet of Things (IoT). The...
A novel intrusion detection approach based on Adaptive Resonance Theory (ART) and Principal Component Analysis (PCA) is put forward according to analyzing now intrusion detection methods. In this model (PCA-MART2), it defines network behaviors relied upon the datagram. PCA is applied to feature selection about input samples and the multi-layered ART2 is designed to subdivide the imprecise clustering...
Frequency hopping (FH) which can hop according to predefined frequency map becomes more and more important in the communications. However if it uses some frequencies which have been interfered, its performance will become worse. This affects communications quality. A new technique, named Spectrum hole detection technique, which is in cognitive radio, is proposed in this paper. And also an AFH system...
