Among cooperative spectrum sensing methods, the Amplify and Forward (AF) technique assumes that SUs relay the received signals without additional processing. In the present paper, inspired by previous works, we introduce a novel cooperative AF scheme with three SUs, where two SUs (denoted as S2 and S3) perform a sequential relaying for the signal transmitted by the third SU (S1) using a Time Division Multiple Access (TDMA) transmission protocol. This sequential relaying requires three consecutive time slots. In the first slot, S1 transmits a test signal; in the second slot, S2 relays the signal received during the first slot; in the third slot, S3 relays the signal received during the second slot. Considering the conventional Energy Detection (ED), the detection probability is estimated analytically and by simulation. Even the novel scheme requires an additional time slot, we demonstrate that the sequential relaying AF scheme outperforms the non-cooperative scheme for almost any topological position of the relaying SUs.","PeriodicalId":405841,"journal":{"name":"2020 13th International Conference on Communications (COMM)","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134135109","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}

Usually, IoT devices have limited resources and Low Power and Lossy Networks (LLNs) are being used to interconnect such devices. Routing Protocol for Low-Power and Lossy Networks (RPL) is one of the preferred routing protocols for this type of network, since it was specially developed for LLNs, also known as IPv6 over Low-Power Wireless Personal Area Networks (6LoWPAN). In this paper the most well-known routing attacks against 6LoWPAN networks were studied and implemented through simulation, conducting a behavioral analysis of network components (resources, topology, and data traffic) under attack condition. In order to achieve a better understanding on how attacks in 6LoWPAN work, we first conducted a study on 6LoWPAN networks and RPL protocol functioning. Furthermore, we also studied a series of well-known routing attacks against this type of Wireless Sensor Networks and these attacks were then simulated using Cooja simulator provided by Contiki operating system. The results obtained after the simulations are discussed along with other previous researches. This analysis may be of real interest when it comes to identify indicators of compromise for each type of attack and appropriate countermeasures for prevention and detection of these attacks.","PeriodicalId":405841,"journal":{"name":"2020 13th International Conference on Communications (COMM)","volume":"221 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123291232","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}

Often e-business integrates different services which communicate with each other. Frameworks and collections of services can be developed in efficient manner using Service Oriented Architecture (SOA). Web services based on Soap protocol and Rest architectural style are key technologies, used to realize e-business applications frameworks. In this paper is presented an e-business platform example, based on SOAP and REST Web services, which can be accessed by mobile users through Android OS Smartphones, while the data traffic amount and cost are optimized. The digital content source is represented by the Bucharest Stock Exchange (BSE), but it also can be retrieved from on-line vendors, e-commerce, e-payment agents etc. A performance evaluation for the e-business SOAP and REST Web services, provided on 4G LTE and IEEE 802.11n WLAN channels, is presented in the paper, in a QoS approach, referring to the response time and throughput. The content and informational tools of the platform can be extended and configured to provide and comply with other types of e-business services as: e-banking, e-commerce, e-payment agents etc, according to different application patterns.","PeriodicalId":405841,"journal":{"name":"2020 13th International Conference on Communications (COMM)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116342938","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 proposed neural system consists of an ensemble of two DCNNs modules for thermal infrared facial image processing; the first module is composed by 12 layers and the second one has 10 layers. The two DCNNs have been trained separately, using different architectures and different sets of parameters. The final decision is influenced by the confidence degrees of two CNN component modules. The proposed method is evaluated using the dataset of 400 thermal infrared facial images belonging to 10 subjects. For each subject the dataset contains 20 thermal images corresponding to sober condition and other 20 images for inebriation condition obtained 30 minutes after the subject has drunk 100 ml amount of whisky. The experiments of the proposed DCNN couple for subject independent drunkenness detection lead to the overall correct detection score of 95.75%. This confirms the effectiveness of the proposed approach.","PeriodicalId":405841,"journal":{"name":"2020 13th International Conference on Communications (COMM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121449454","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}
