In RSS (Received Signal Strength)-based localization, the radio propagation model of a RFID (Radio Frequency IDentification) tag based on the RSSI (Received Signal Strength Indicator) measurements is used to convert the signal strength into distance. However, the propagation model for a single tag in one direction is not too accurate due to large deviations in the measured RSSI values. In this paper, an approach using a single RFID tag is presented. Performances of a single active UHF-RFID tag operating at 433 MHz are examined. Distance estimations are determined using the One-Slope Model (OSM). Improvements in distance estimations for different angles are based on an averaging algorithm which allows detecting the attenuation of the signal in a series of positions of the reader antenna. In addition, the Path Loss Exponent 'n' is also determined in different positions. Further, Experimental validations show the evolution of the Power when the distance (tag-reader) increases. Then, the Path loss contours, for measured distances, are plotted.","PeriodicalId":398620,"journal":{"name":"2018 IEEE Middle East and North Africa Communications Conference (MENACOMM)","volume":"126 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127971237","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}

This paper presents a novel algorithm that debugs throughput of Total-Order Broadcast primitives automatically in the multi-datacenter environments.

This work reveals the potential of Wikipedia mining for geopolitical study. Actually, Wikipedia offers solid knowledge and strong correlations among countries by linking web pages together for different types of information (e.g. economical, historical, political, and many others). The major finding of this paper is to show that meaningful results on the influence of country ties can be extracted from the hyperlinked structure of Wikipedia. We leverage a novel stochastic matrix representation of Markov chains of complex directed networks called the reduced Google matrix theory. For a selected small size set of nodes, the reduced Google matrix concentrates direct and indirect links of the million-node sized Wikipedia network into a small Perron-Frobenius matrix that preserves the PageRank probabilities of the global Wikipedia network. We perform a novel sensitivity analysis that leverages this reduced Google matrix to characterize the influence of relationships between countries from the global network. We apply this analysis to the set of 27 European Union countries. We show that with our sensitivity analysis we can exhibit easily very meaningful information on geopolitics from five different Wikipedia editions (English, Arabic, Russian, French and German).","PeriodicalId":398620,"journal":{"name":"2018 IEEE Middle East and North Africa Communications Conference (MENACOMM)","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117190084","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}

These methods are used to measure the complex relative permittivity (ερ) and complex relative permeability (μ^) of a material under test (MUT). In these methods, post processing algorithms such as Thru-Reflect- Line (TRL) Calibration and Nicolson-Ross-Weir (NRW) are employed to provide the required calibration standards and conversion tools. They, along with the frequency domain scattering parameters, characterize the dielectric properties of the MUT. The proposed methods can be employed in different applications that range from electronics manufacturing, to biomedical implementation, and industrial food production. These methods are compared and analyzed in this paper. Several experiments are conducted to validate the proposed techniques. These techniques are adjusted to reduce the constraints on MUT while maintaining acceptable accuracy.","PeriodicalId":398620,"journal":{"name":"2018 IEEE Middle East and North Africa Communications Conference (MENACOMM)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129638059","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}

As Data Mining is the main key step in Knowledge Discovery process in Databases (KDD), it is necessary to find a new methodology that combines web data extraction playing the role of data collection from the web and data mining techniques on the extracted categorical data in order to discover knowledge. The main contribution of this research is proposing a methodology to apply the clustering notion on categorical web data and to use the clustering results as part of the input for the classification conducted on another set of data. Data mining and relative data processing are conducted by developing intelligent tools. The performance of the algorithms used in our methodology is demonstrated with the clustered job postings dataset and classified job searchers dataset by using the three measures accuracy, recall and precision for the clustering algorithm and the error of classification for the classification technique. The results show that our proposed approach of combination ends up with good results in Knowledge Discovery from the web.","PeriodicalId":398620,"journal":{"name":"2018 IEEE Middle East and North Africa Communications Conference (MENACOMM)","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122530132","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}

Bahi","doi":"10.1109/MENACOMM.2018.8371008","DOIUrl":"https://doi.org/10.1109/MENACOMM.2018.8371008","url":null,"abstract":"There is not a proper mathematical definition of chaos, we have instead a quite big amount of definitions, each of one describes chaos in a more or less general context. Taking in account this, it is clear why it is hard to design an algorithm that produce random numbers, a kind of algorithm that could have plenty of concrete appliceautifat (anul)d bions. However we must use a finite state machine (e.g. a laptop) to produce such a sequence of random numbers, thus it is convenient, for obvious reasons, to redefine those aimed sequences as pseudorandom; also problems arise with floating point arithmetic if one wants to recover some real chaotic property (i.e. properties from functions defined on the real numbers). All this considerations are synthesized in the problem of the Pseudorandom number generators (PRNGs). A solution to these obstacles may be to post-operate on existing PRNGs to improve their performances, using the so-called chaotic iterations, i.e., specific iterations of a boolean function and a shift operator that use the inputted generator. This approach leads to a mathematical description of such PRNGs as discrete dynamical systems, on which chaos properties can be investigated using mathematical topology and measure theory. Such properties are well-formulated, and they allow us to characterize which functions improves the sensitivity to the seed, the expansivity, the ergodicity, or the topological mixing of the generator resulting from such a post-processing. Experience shows that choosing relevant boolean functions in these chaotic iterations improves the randomness of the inputted generator, for instance when considering the number of statistical tests of randomness passed successfully. If we focus on the cryptographical application of PRNGs, there are two main classical notions to be considered, namely collision and avalanche effect. In this article, we recall the chaotic properties of the proposed post-treatment and we study the collision property in families of pseudorandom sequences produced by this process.","PeriodicalId":398620,"journal":{"name":"2018 IEEE Middle East and North Africa Communications Conference (MENACOMM)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121836403","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}

Many businesses rely on this technology to keep their systems running but concerns are rising about security breaches in cloud computing. Cloud providers (CPs) are taking significant measures to maintain the security and privacy of the data stored on their premises, in order to preserve the customers' trust. Nevertheless, in certain applications, such as medical health records for example, the medical facility is responsible for preserving the privacy of the patients' data. Although the facility can offload the overhead of storing large amounts of data by using cloud storage, relying solely on the security measures taken by the CP might not be sufficient. Any security breach at the CP's premises does not protect the medical facility from being held accountable. This work aims to solve this problem by presenting a secure approach for storing data on the cloud while keeping the customer in control of the security and privacy of their data.","PeriodicalId":398620,"journal":{"name":"2018 IEEE Middle East and North Africa Communications Conference (MENACOMM)","volume":"51 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132772611","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}
