In this paper, we introduce an auction-based resource allocation scheme between a spectrum broker and base stations (BS)s that belong to a wireless service provider (WSP). Each BS submits the proportion of resources it wishes to lease from each auctioned spectrum band based on its true demand and the auctioneer's offered price. The spectrum broker leases the resource blocks (RB)s of its under-utilized spectrum bands to the WSP base stations using an iterative resource allocation algorithm. The proposed algorithm is based on a fair spectrum auction. The spectrum broker who manages the under-utilized spectrum resources plays the role of an auctioneer. First, we establish utility functions for the auctioneer and each participating BS. Then we maximize these utilities in iterations in order to achieve optimal price and allocated resources. Furthermore, we introduce a cheat-prevent auction mechanism based on ascending-bid auction to prevent greedy BSs from cheating activities to obtain lower prices for the auctioned resources. Finally we present simulation results on the performance of the proposed resource leasing mechanism.","PeriodicalId":222207,"journal":{"name":"2019 International Conference on Wireless Networks and Mobile Communications (WINCOM)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125962805","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}

{"title":"Ethereum for Secure Authentication of IoT using Pre-Shared Keys (PSKs)","authors":"Mohammad El-Hajj, A. Fadlallah, M. Chamoun, A. Serhrouchni","doi":"10.1109/wincom47513.2019.8942487","DOIUrl":"https://doi.org/10.1109/wincom47513.2019.8942487","url":null,"abstract":"Enterprises are no doubt interested in reaching data collected from billions of Internet of Things (IoT) devices which opens a huge potential business. The main concern remains the security challenges from the distribution of key while using public key cryptography. To ensure that IOT connected devices can be trusted to be what they are supposed to be, robust IoT device authentication is mandated. Each IoT device therefore requires a unique identity which can be verified when the device tries to link to an intermediate device. One of the early solutions used to secure data transmission among parties in public networks is the Public Key Infrastructure (PKI) which is used to distribute and manage public keys (digital certificates) among different parties and these certificates are generated upon request by Certificate Authorities (CA). Nevertheless, for billions of devices connected to IoT and mobile phones, the distribution management of certificates for each client proved to be inefficient. In this research, we propose a decentralized authentication platform based on PKI and Ethereum Blockchain. The public key certificates are stored in a decentralized fashion and the private keys are stored inside the devices themselves. It also includes a protocol for Pre-Shared Keys (PSK) distribution. PSK keys are then used by PSK-based security protocols for securing the communication channel between two devices. This platform includes a client-side module, a server-side Wallet Management Function, and a smart contract deployed on the Ethereum Blockchain network. This platform can be used by applications for end devices and/or intermediate devices authentication and a secure Machine-to-Machine (M2M) communication. The proposed platform is validated by the implementation of a Secure Session Establishment between IoT devices. Results show that the solution implementation has minimal impact on the existing networks, and the secure session setup time between two devices is negligible compared to the existing security methods. Eventually, this scheme can help removing the trust requirement placed on clients by the current PKI/CAs infrastructure.","PeriodicalId":222207,"journal":{"name":"2019 International Conference on Wireless Networks and Mobile Communications (WINCOM)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127304180","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 optical performance of solar collectors is very sensitive to the optical errors and geometric inaccuracies and assembly of structures. Therefore, to maintain high optical performance, an accurate technique to monitor and adjust the solar collectors' quality in their essential steps and during operation is essential. In this paper, the distant observer method is presented and described as the suitable technique for field measurement that requires a low pre-arrangement effort and measurement time. The field measurement setup of the proposed technique based on the distant observer method and image processing algorithms is presented, in which a parabolic trough collector installed on the research platform Green Energy Park (Benguerir, Morocco) is evaluated. Roberts, Prewitt and Sobel contour detection algorithms are used to detect the reflected image of the absorber tube. In addition, a neural network algorithm is proposed to rapidly and precisely detect the parabolic trough form.","PeriodicalId":222207,"journal":{"name":"2019 International Conference on Wireless Networks and Mobile Communications (WINCOM)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131210209","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}

By using both techniques: Tone Reservation (TR) and Clipping (CL), which have a certain complementarity, we can improve their performance in terms of convergence speed, transmission quality through Error Vector Magnitude (EVM) and Bit Error Rate (BER) results. The TR technique exploits the null sub-carriers in communications standards in order to generate a correction signal used to reduce the PAPR. Nevertheless, this method has limited performances due to the reduced number of the available sub-carriers. For this purpose, our contribution is to introduce a new approach for the TR technique based on Preconditioned Conjugate Gradient (PCG) optimization algorithm combined with the CL technique. The simulations with WiMax 802.16e standard shown that this new technique realizes an increased PAPR reduction compared to the classical and more recent methods with similar parameters.","PeriodicalId":222207,"journal":{"name":"2019 International Conference on Wireless Networks and Mobile Communications (WINCOM)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124746517","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}

Vehicular Ad hoc NETworks (VANETs) represent important opportunities to exploit content that virtual service providers (VSPs) offers. The concept of “Cache as a Service (CaaS)” is a promising technique to minimize the average latency while satisfying the QoE requirements of vehicles. In this paper, we mainly consider the problem of optimizing latency in ITS, exploiting a completely virtualized environment and caching feature. In this perspective, virtual service providers (VSPs) and mobile virtual network operators (MVNOs) are connected in the Cloud through network as a service (NaaS), using distributed infrastructure as a service (IaaS). VSPs provide services according to VANETS movement. The VANET, as service requester will take advantage of emerging caching techniques (CaaS) to accomplish the on-demand low-latency services requiring computing resources and bandwidth. Consequently, we propose a many-to-many matching strategy coupled to CaaS caching capabilities on distributed F-RAN between VANET and virtual service provider (VSP). We exploit the deferred acceptance algorithm to solve this game. To highlight the effectiveness of our approach, we applied it on two typical on-demand services requiring ultra-reliability and low-latency communications (uRLLC): The intelligent transport and the video streaming services. The simulation results demonstrate the effectiveness of our approach in terms of improved latency and bandwidth optimization and especially during periods of traffic congestion.","PeriodicalId":222207,"journal":{"name":"2019 International Conference on Wireless Networks and Mobile Communications (WINCOM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127961274","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}
