Massive MIMO is widely seen as the most promising 5G radio technology as it promises very high throughput to many users while also guaranteeing fairness, thanks to the channel hardening effect limiting the small-scale fading. A key question though is to what extent this achieved throughput is homogeneous among users, and what degrees of freedom exist to improve fairness. A promising option to provide uniform throughput using Massive MIMO would be a proper power control, based on long-term channel statistics. This paper studies the trade-off between throughput and fairness and it compares different power-allocation schemes. Assuming users affected by log-normal large-scale fading, simulations show that the trade-off is critical. as user-dependent differences caused by large-scale fading are causing unfairness in the system and fairness is achieved at the price of throughput reduction. In a limited large-scale fading scenario, throughput or fairness optimization is possible without incurring huge losses on the other dimension. For heavy large-scale fading scenarios the cost of enforcing fairness is very large: more than 50% of throughput reduction is observed. Despite the critical trade-off, Massive MIMO is shown to be less sensitive to throughput losses when enforcing fairness, compared with traditional communication systems.","PeriodicalId":226008,"journal":{"name":"2017 IEEE Symposium on Communications and Vehicular Technology (SCVT)","volume":"426 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115998822","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}

Various RATs can offer different throughputs, and thus RAT selection plays an important role in quality of service provisioning. In this paper, considering a heterogeneous network with two throughput classes, we introduce a new practical probabilistic RAT selection approach. In contrary to the common deterministic approaches, in this scheme, each user performs the RAT selection periodically in a random manner using an association probability determined by a central unit in the network. The user remains connected to the selected RAT for a specific amount of time and then again performs the selection. To find the association probabilities, the network throughput maximization is formulated. Since the resulting problem is not convex, we propose two alternatives, one with sub-optimal solution but lower complexity and one with the use of change of variables with optimal solution. Finally, numerical simulations demonstrate the superior performance of our proposed schemes in comparison to several possible approaches. Also, these numerical investigations indicate that our sub-optimal method works very close to the optimal one.","PeriodicalId":226008,"journal":{"name":"2017 IEEE Symposium on Communications and Vehicular Technology (SCVT)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117008231","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}

Three coding configurations are investigated. In the first configuration (C1), the PON link and the TP link are protected by a Reed-Solomon (RS) code and trellis-coded modulation (TCM), respectively. In the second configuration (C2), the PON link is the same as with C1, but the TP link is now protected by the concatenation of an outer RS code and inner TCM. We compare these conventional coding configurations C1 and C2 with an alternative configuration (C3), in which an outer RS code protects the cascade of the uncoded PON and the TCM-encoded TP. Whereas the configuration C3 has the same complexity as the configuration C1, we show that the former is able to achieve approximately the same information bitrate as the (more complex) configuration C2, at the expense of a slightly (about 1 dB) higher optical power. Our numerical results for a typical setting indicate that the configurations C2 and C3 can provide information bitrates beyond 10 Gbps, which are about 20–25% larger than for configuration C1.","PeriodicalId":226008,"journal":{"name":"2017 IEEE Symposium on Communications and Vehicular Technology (SCVT)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129201853","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 emissions contain intrinsic features of the device itself. RF fingerprinting can be used to enhance the security of wireless networks since the fingerprints provide a form of authentication complementing other measures. RF-based authentication turns out to be of practical use in security applications as long as the RF fingerprinting delivers high identification and verification accuracy, and the whole process is computationally efficient. In this paper, we investigate a novel approach to RF fingerprinting based on the application to time series of the Symbolic Aggregate Approximation algorithm (SAX). This is a compression scheme known to be time efficient and, although it has been applied to many domains, it has so far never been investigated in the problem of RF fingerprinting. We demonstrate that a SAX-based approach provides a very high identification accuracy (over 99%), and turns out to be attractive, as compared to classification without SAX, from both a computational standpoint and its robustness to noise.","PeriodicalId":226008,"journal":{"name":"2017 IEEE Symposium on Communications and Vehicular Technology (SCVT)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134033977","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 evaluation is performed using a virtual environment so that the obtained results are similar to the expectations of a real world testbed. According to the specific requirements in disaster situations, three different scenario categories are implemented. The focus of the scenarios defined in the first category is to evaluate the behavior of the protocols inside a static network. The focus in the second category is to test their performance after dynamic processes. The focus in the last category is to predict the behavior of the routing protocols inside a large network expected after a disaster. The obtained results can be interpreted as follows: in the first category, the results obtained by HWMP and B.A.T.M.A.N. advanced are similar. Both protocols take the variations in the link throughput into consideration for their routing operations. In the second category, the protocol HWMP shows the most promising results concerning dynamic processes inside the network. The results obtained in the last category show that none of the examined protocols is appropriate for large networks, with the exception of Babel, which can be modified to support a large number of clients and routers. Because none of the examined routing protocols can fulfil the requirements in disaster situation, a new network architecture is proposed, which combines the advantages of two routing protocols to address the existing routing challenges.","PeriodicalId":226008,"journal":{"name":"2017 IEEE Symposium on Communications and Vehicular Technology (SCVT)","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133384826","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 future deployment of V2X necessitates interworking between different access technologies, i.e., Dedicated Short-Range Communications (DSRC) and Cellular networks. However to achieve an efficient V2X interworking, we need to resolve the multi-hop issue, mainly originating from the V2X hybrid architecture. To resolve this issue and consequently to analyze the interconnected system, characterizing the output process of IEEE 802.11p-based DSRC protocol is of a fundamental importance. This paper proposes stochastic Regenerative Model to provide a complete description of IEEE 802.11p output process. The accuracy of the model is verified through extensive simulations. As a case study, the proposed model is compared with the Poisson model in the performance evaluation of V2X interworking. Numerical and simulation results verify the ability of the Regenerative Model to capture the deviations of the actual output process of IEEE 802.11p under different traffic intensity as compared to the Poisson model.","PeriodicalId":226008,"journal":{"name":"2017 IEEE Symposium on Communications and Vehicular Technology (SCVT)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115479883","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}
