The current large-scale Internet of Things(IoT)networks typically generate high-velocity network traffic *** use IoT devices to create botnets and launch attacks,such as DDoS,Spamming,Cryptocurrency mining,Phishing,*** service providers of large-scale IoT networks need to set up a data pipeline to collect the vast network traffic data from the IoT devices,store it,analyze it,and report the malicious IoT devices and types of ***,the attacks originating from IoT devices are dynamic,as attackers launch one kind of attack at one time and another kind of attack at another *** number of attacks and benign instances also vary from time to *** phenomenon of change in attack patterns is called concept ***,the attack detection system must learn continuously from the ever-changing real-time attack patterns in large-scale IoT network *** meet this requirement,in this work,we propose a data pipeline with Apache Kafka,Apache Spark structured streaming,and MongoDB that can adapt to the ever-changing attack patterns in real time and classify attacks in large-scale IoT *** concept drift is detected,the proposed system retrains the classifier with the instances that cause the drift and a representative subsample instances from the previous training of the *** proposed approach is evaluated with the latest dataset,IoT23,which consists of benign and several attack instances from various IoT *** classification accuracy is improved from 97.8%to 99.46%by the proposed *** training time of distributed random forest algorithm is also studied by varying the number of cores in Apache Spark environment.

American Journal of Plant Sciences 2017年第12期8卷 2995-3012页

作者： Arumugam Nagarajan saravanan soorangkattan Kavitha Thangavel Boobalan Thulasinathan Jothi Basu Muthuramalingam Arun Alagarsamy Under Graduate Lab Department of Biotechnology Bhupath and Jyoti Mehta School of Biosciences Indian Institute of Technology-Madras Chennai India Department of Botany School of Life Sciences Alagappa University Karaikudi India Department of Microbiology School of Life Sciences Alagappa University Karaikudi India

The floristic diversity of plants and their abundance were analyzed in 2.5 km campus to explore their medical importance by random sampling. The results for plant diversity in IIT-M campus showed nearly 100 species of flowering plants, with genera belonging to nearly 40 families. The most dominant family in the present study is Fabaceae with 15 species (25%) of the medicinal trees. In addition, the dominant medicinal herbs belong to the families of Acanthaceae, Apocynaceae, Fabaceae and Rubiaceae containing 4 species (12%) each. The identified medicinal tree and herb are verified with Red data book to explore their conservation status of every identified medicinal trees and herbs. On comparison with the existing IUCN red data list, the conservation status of 73% of trees and herbs identified in the present study were not assessed. Also, the biodiversity of plants focused on ethano-botanical aspects to reveal their medicinal uses.
