Yet, adoption of SDN is contingent on a thorough analysis of security implications. In this paper, we investigate a man-in-the-middle (MITM) attack that exploits the centralized topological view critical to SDN operations. In particular, we present a new scheme for detection and classification of the attack at the network layer. We apply wavelet analysis to detect anomalous conditions introduced by the MITM attack using traffic signals collected at network switch ports. We then identify unique characteristics of reported anomalies in the collected traffic signals to build a classification framework. Other cyber events, such as a distributed denial-of-service and network congestion, are presented to the detection scheme to validate its general applicability. Overall, we successfully demonstrate the capability to detect and classify the MITM attack in addition to other cyber events at the network layer, thereby contributing to the security of SDN.","PeriodicalId":179948,"journal":{"name":"2018 12th International Conference on Signal Processing and Communication Systems (ICSPCS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134076926","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The size and the power capacity of capsule endoscopy have been the main bottlenecks to achieve an efficient locomotion design. Running a locomotion device for a long time it seems to be impossible without the utilization of an external magnetic field that has been found to be unsafe for human risks. A short utilization of a locomotion mechanism, which is controlled from outside the capsule, could solve the problems of size and power capacity limitations. The short utilization of the simplified design could solve a major risk of capsule endoscopy which is capsule retention. This paper is set out to investigate the feasibility of developing an internal capsule retention release mechanism to solve the problem of capsule endoscopy retention. This includes the design and configuration of new capsule model to mount the proposed locomotion system. Two types of motors were tested in this paper; these are a two-phase stepper motor and a coin-type vibration motor. The design of the printed circuit board (PCB) of the nRF51×822 was reconfigured to fit within the small dimensions of the new model. The operation performance of both motors using a limited power source has been recorded which show that the proposed design is able to work efficiently for a limited time. However, a number of steps need to be undertaken to realize the feasibility of the new design for practice which includes testing in an animal or a fabricated model that allow for peristaltic movement similar to the human GI tract movement.","PeriodicalId":179948,"journal":{"name":"2018 12th International Conference on Signal Processing and Communication Systems (ICSPCS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125125467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, gaining insight into the fundamentals and explaining their functionality is an open research area of high interest. In this paper, we use an information theoretic approach to reveal typical learning patterns of ANNs. For this purpose the training samples, the true labels, and the estimated labels are considered as random variables. Then, the mutual information and conditional entropy between these variables are studied. We show that the learning process of ANNs consists of essentially two phases. First, the network learns mostly about the input samples without significant improvement in the accuracy, thereafter the correct class allocation becomes more pronounced. This is based on investigating the conditional entropy of the estimated class label given the true one in the course of training. We next derive bounds on the conditional entropy as a function of the error probability, which provide interesting insights into the learning behavior of ANNs. Theoretical investigations are accompanied by extensive numerical studies on an artificial data set as well as the MNIST and CIFAR benchmark data using the widely known networks LeNet-5 and DenseNet. Amazingly, in all cases the bounds are nearly attained in later stages of the training phase, which allows for an analytical measure of the training status of an ANN.","PeriodicalId":179948,"journal":{"name":"2018 12th International Conference on Signal Processing and Communication Systems (ICSPCS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122962389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The detection of the NLOS propagation is very important to guarantee the accuracy of the UWB system. Based on the channel impulse response (CIR) sample, the NLOS condition could be identified. However, for the decawave chips, each CIR sample contains 1015 points. Thus the real-time realization of the NLOS detection with CIR is very hard, since the import and calculation of such a large amount of data cause to huge delay. In order to reduce the delay, the minimal needed size of the points in CIR for accurate NLOS identification is discussed in this paper. The support vector machine (SVM) is used for the classification based on the original CIR points or the eight different features extracted from each CIR. Furthermore, a new method is proposed for the identification based on the convolution algorithm. Compared to the existing approach with CIR, the needed CIR points for the detection are dramatically reduced, which makes the on-line identification realization possible. The accuracy of the NLOS identification with less CIR points is even better. The new proposed method using convolution algorithm also shows very promising results compared the other approaches.","PeriodicalId":179948,"journal":{"name":"2018 12th International Conference on Signal Processing and Communication Systems (ICSPCS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126760730","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
