Although this is simple with a very short detection time, the competitive behavior of secondary users can lead to additional expenses in terms of energy. Indeed, the contention on data channel unoccupied by licensed user leads to a single winner, but also involves a loss of energy of all nodes. In this paper, we investigate the problem of energy efficient spectrum sensing, by applying an approach based on regret-matching learning, to improves secondary users battery life and the performance of the network. We will demonstrate by simulations, that the regret matching learning can achieve good results.","PeriodicalId":103830,"journal":{"name":"2018 International Conference on Advanced Communication Technologies and Networking (CommNet)","volume":"192 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116111888","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}

For example, if we request the cloud computing to do a huge treatment over our encrypted big data it should decrypt it at first, which means revealing the private encryption key to an untrusted part and that constitute a security problem. Processing encrypted data in cloud computing is an efficient solution. Homomorphic encryption schemes are powerful tools that allow performing computations over ciphertexts without any prior decryption. We propose a new efficient homomorphic encryption scheme based on Lucas theorem. Our cryptosystem allows performing several AND gates over encrypted cloud data. The cost of one AND of two ciphertexts is equivalent to the cost of addition on numbers. The proposed scheme uses the {0,1} as cleartext space and one key for encryption and decryption, i.e it is a symmetric encryption scheme.","PeriodicalId":103830,"journal":{"name":"2018 International Conference on Advanced Communication Technologies and Networking (CommNet)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125126675","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}

One strategy to deal with this challenge is to reduce, as much as possible, the number of the discovered services using different mechanisms such as semantic Web-based clustering. However, most existing approaches are better suitable for static context and don't consider the dynamicity of services and gateways. Moreover, most of them are centralized approaches. In this paper we propose a distributed WoT services semantic discovery architecture. Our architecture leverages three services filtering mechanisms: clustering, indexing and ranking, which are semantic annotation-based. Also, this architecture takes into account both the dynamicity of WoT services through an incremental clustering algorithm, and the mobility of IoT gateways, through WoT gateways.","PeriodicalId":103830,"journal":{"name":"2018 International Conference on Advanced Communication Technologies and Networking (CommNet)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129279913","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, in practical communication scenarios, transceiver architectures inevitably suffer from radio-frequency (RF) front-end related impairments that can lead to degradation of the overall system performance, with in-phase/quadrature-phase imbalance (IQI) constituting a major impairment in direct-conversion transceivers. In the present work, we quantify the effects of joint transmitter/receiver IQI on the performance of NOMA based multi-carrier (MC) systems under multipath fading conditions. Furthermore, we derive the asymptotic diversity order of the considered MC NOMA set up. Capitalizing on these results, we demonstrate that the effects of IQI differ considerably among NOMA users and depend on the underlying system parameters. For example, it is shown that the first sorted user appears more robust to IQI, which indicates that higher order users are more sensitive to the considered non-negligible impairment.","PeriodicalId":103830,"journal":{"name":"2018 International Conference on Advanced Communication Technologies and Networking (CommNet)","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127987883","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}

Because of the development in hardware, software, and communication technologies. However, real-time applications are facing several challenges for providing reliable communications (V2V and V2I) due to many effective factors which increase the rate of topology change, including high-speed mobility and sparse vehicle density. In this paper, we first establish a real-time path planning strategy which utilizes real-time information about traffic conditions for providing the shortest paths with minimum travel time. This strategy utilizes vehicular ad hoc networks (VANETs) to enable real-time communications among vehicles, roadside units (RSUs), and a central server. Each vehicle can request a shortest-path by sending a simple request packet to the server and waiting for a reply containing a new route as sequence of turning movements. Finally, our path planning strategy is implemented and simulated based on a real map by using Veins framework (with IEEE 802.11 p/WAVE standard). Veins is capable of running OMNET++ and SUMO in parallel. Simulation results confirm that our proposed path planning approach improves significantly the travel time.","PeriodicalId":103830,"journal":{"name":"2018 International Conference on Advanced Communication Technologies and Networking (CommNet)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116143993","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}

On the other hand, though the understanding of individual factor influencing the pathogenesis has progressed biologically and clinically, theoretical study of the integrated dynamics leading to the calculus of urolithiasis through the crystal growth and aggregation from the crystal nucleation using a mathematical model has not been made yet. Then I derived the mathematical model of the process leading to the onset of urolithiasis so as to clarify how a variety of factors affecting urolithiasis influence the pathogenesis quantitatively. In the mathematical model, the process leading to the onset of urolithiasis is divided into the following three processes. (1) formation of crystal nuclei. (2) formation of calculi by growth of crystal nuclei. (3) bonding of calculi to urinary tract cells and growth of calculi. In addition, the parameters of the volume of the urinary tract, the flow rate of urine etc. are introduced to represent the characteristics of the urinary tract. As a result, for instance, in case of calcium oxalate calculi, the conditions that the calculus does not grow were shown analytically and numerically. And the dependence of the growth of the calculus on the volume of the urinary tract or the flow rate of urine was also clarified analytically and numerically. Then, based on the analysis of this mathematical model, we propose specific solutions in clinical.","PeriodicalId":103830,"journal":{"name":"2018 International Conference on Advanced Communication Technologies and Networking (CommNet)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121157096","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}
