The most of the WSN applications involve indoor environments and low costs requirements, so the Global Position System cannot always assure a reliable operating and cheap solution. As a consequence, other methods have to be considered for nodes locating, among all, the most widespread methods are based on Received Signal Strength Indicator (RSSI) measurements. The main advantage of this method is that it does not require additional hardware since the measurement of RSSI is often built-in in radio chipsets for the most common standards in use for a WSN (Bluetooth, Wi-Fi, ZigBee). However, solutions based on RSSI measurements suffer of high uncertainty due to several phenomena as high variability of RSSI measurements, external interferences and multipath to cite a few. In this paper the influence of the multipath is investigated and the effects of different processing techniques for multipath mitigating, based on the employment of frequency diversity, are analyzed in simulation environment and in real scenarios.","PeriodicalId":440636,"journal":{"name":"2015 IEEE International Workshop on Measurements & Networking (M&N)","volume":"10 24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114185992","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}

Unlike the first scenario, the second one is a new research path that has received less attention in the scope of Intrusion Detection System (IDS) research. The term “unsupervised” refers to the method ability to select the optimal number of components automatically without the need of careful initialization. Experiments are carried out using a public dataset collected from a real network. Favorable results indicate the effectiveness of unsupervised GMMs.","PeriodicalId":440636,"journal":{"name":"2015 IEEE International Workshop on Measurements & Networking (M&N)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115430200","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 context emerged with the Internet of Things (IoT), where different technologies connected with the Internet provide several applications to change people's lifestyle. However, such integration of heterogeneous devices causes many problems of security and privacy due vulnerabilities of technologies, carrying important consequences to the users of IoT technologies. In this context, we proposed a reference ontology (IoTSec) with security concepts of M2M communications to help find secure solutions to the IoT environment. We followed a literature review and MENTOR methodology to gather and harmonize security ontologies and knowledge of vulnerabilities, which are the root causes for problems of all information security. In order to elucidate our approach, we describe a case study about the applicability of IoTSec in the industrial scenario.","PeriodicalId":440636,"journal":{"name":"2015 IEEE International Workshop on Measurements & Networking (M&N)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128241497","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 approach in fact does not require the installation of external devices since it relies on low-cost devices of common use, like smartphones, which are used both as measurement platform and user interface. In this paper we focus the attention on implementing algorithms for estimating and tracking the heading direction of a user while he/she is walking inside a building. The novelty of the method here proposed, is that it does not refer to an absolute estimation of the heading direction of a user with respect to the four cardinal directions, as usually done in literature. The method proposed in this paper is based on detecting relative changes in the direction of a user with respect to a reference system obtained during an initial calibration phase. Then, the fundamental direction which exhibits the minimum ℓ2-norm distance with respect to the raw measured values is provided in output. As it can be noted from experimental results reported in the paper, the direction of a user can be detected with a sufficient reliability.","PeriodicalId":440636,"journal":{"name":"2015 IEEE International Workshop on Measurements & Networking (M&N)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124229162","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 devices are fed through the electrical grid, which in turn supplies multiple devices simultaneously. The normal operation of an equipment can produce quality events in the power bus that can lead others to fail. This justifies the need for a wireless network of sensors (WSN) spread through the electrical installation. In addition, a wireless solution results in easiness of installation and maintenance. The main task of a WSN will be to monitor in real time the occurrence of power quality events. These goals will demand the development of efficient computational algorithms to detect and report these quality events through the network. In this paper two different solutions are described and compared. In a first approach the wavelet transformation is used for event detection. This solution is afterwards compared with a less computational demanding algorithm based on segmentation and labelling which also compacts the information to be transmitted.","PeriodicalId":440636,"journal":{"name":"2015 IEEE International Workshop on Measurements & Networking (M&N)","volume":"141 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127325690","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}

USRP Hardware Driver (UHD) gain is a supplementary amplification parameter available to the user, nonetheless its manipulation has to be done with care.

The wearable device is able to recognize critical events like falls or prolonged inactivity, to monitor the user posture and to send an alarm to a centralized monitoring system which will broadcast the alarm to caregivers alert devices. The paper focuses on the smart algorithms developed for the classification of the ADL (Activities of Daily Living) which use the information from the inertial sensors installed on the user device. In particular a novel, with respect to the State Of The Art, multi-sensor data fusion approach, combining data from the onboard accelerometer and the gyroscope is presented.

The considered node is tailored for wide area sensors networks aimed to carry out measurements in frequency domain. To this aim, the node takes advantage from some known or recently proposed CS features in such a way as to outperform the nominal specification of its data acquisition module. To make the spectrum estimation feasible on the node level, a suitable strategy for input signal random sampling and an efficient CS implementation, i.e. the greedy algorithms based on the so-called match-pursuit approach, are exploited. First tests are presented, related to a cost-effective microcontroller from STMicrocontroller, namely STM32F429ZI, characterized by a data memory depth sufficient to execute the agile computational scheme of the greedy algorithm. The estimated spectra concur with those obtained through standard discrete Fourier transform-based approaches, thus highlighting the feasibility of the proposed measurement node.","PeriodicalId":440636,"journal":{"name":"2015 IEEE International Workshop on Measurements & Networking (M&N)","volume":"357 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123339098","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}
