The possibility of providing CCAM services along different countries when vehicles traverse various national borders has a huge innovative business potential. However, the seamless provision of connectivity and the uninterrupted delivery of real-time services along borders also pose technical challenges which 5G technologies promise to solve. The situation is particularly challenging given the multi-country, multi-operator, multi-telco-vendor, multi-car-manufacturer, and cross-generation scenario of any cross-border layout. Motivated by this, the 5GCroCo project, with a total budget of 17 million Euro and partially funded by the European Commission, aims at validating 5G technologies in the Metz-Merzig-Luxembourg cross-border corridor, traversing the borders between France, Germany and Luxembourg. 5GCroCo validation will focus on three use cases: 1) tele-operated driving, 2) high definition map generation and distribution for automated vehicles, and 3) Anticipated Cooperative Collision Avoidance. The results will help reduce the uncertainties associated with eV2X communications across borders in Europe in preparation of commercial 5G deployment.","PeriodicalId":112723,"journal":{"name":"2019 European Conference on Networks and Communications (EuCNC)","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116696786","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 paper proposes a novel hybrid content caching replacement algorithm in MEC to increase its caching efficiency where future request references are predicted using a polynomial fit algorithm along with Lagrange interpolation. Additionally, a distributed co-operative caching algorithm to improve data access within MECs.

We propose to realize these network functionalities directly in the dataplane, exploiting the characteristic of FlowBlaze, a novel stateful programmable dataplane.

Assuming that the Virtual Network Operators (VNOs) guarantee contracted Service Level Agreements (SLAs) with the users, the proposed approach uses weighted proportional fairness as a basis for allocation of the remaining capacity. This allocation is achieved by a distributed, pricing-based solution to a two-layer convex optimization problem. Through this mechanism, some of the key functionalities of the centralized virtualization platform are transferred to the individual VNOs and users. This allows for a drastic reduction in the complexity of the system management compared to the previously proposed centralized approaches. Therefore, it leads to a much more scalable design for dense network deployments with real-time applications. Another advantage of the proposed distributed cross-layer optimization is the enhanced level of isolation among different VNOs. The proposed approach is evaluated by simulating a scenario with 3 types of VNOs and differentiated SLAs sharing radio resources from an underlying physical heterogeneous network. Results for the 4 types of service classes confirm that given sufficient aggregate capacity, all SLAs are satisfied, the entire aggregated capacity is utilized, and the residual available capacity is shared among the users proportionally fair.","PeriodicalId":112723,"journal":{"name":"2019 European Conference on Networks and Communications (EuCNC)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127758568","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}

In this paper, we propose two methods for finding the message from the codeword in a QC-LDPC code. The first method is a general scheme which views the problem as a set of linear equations. This method is not realizable with pure digital circuits and may be implemented by having a processor core in the design. The second method is rather an alternative scheme which makes use of a particular structure in generator matrices of QC-LDPC codes in order to find the message from a non-systematic codeword. We examine a large class of non-systematic Latin squares QC-LDPC codes and one of the IEEE 802.16e standard QC-LDPC codes, and show that they have the required structure to be usable by the algorithm. The latter method is realizable in hardware and can be implemented with a digital circuit consisting of XOR gates.","PeriodicalId":112723,"journal":{"name":"2019 European Conference on Networks and Communications (EuCNC)","volume":"2017 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127554457","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}

Counting Bloom filters address this drawback using counters at the expense of increased filter size. Other alternatives like the Deletable Bloom Filter (DlBF) or the Ternary Bloom Filter (TBF) have been proposed to maintain a small filter size while supporting deletions of elements with some probability. These structures offer different trade-offs between deletability, false positive rate and filter size. In this paper, we propose a new filter called the D-FP (Deletable Fingerprint) Bloom filter that stores two-bit fingerprints, instead of a single bit or a counter, that can indicate whether the item can be deleted. By using the fingerprints, the D-FP Bloom filter provides lower false positive rates than the TBF at low filter occupancies and better deletability than the DlBF thus providing more options to desginers that want to trade-off both parameters. In addition to presenting the D-FP Bloom filter, this paper also presents an analysis of the effects of deletions on the performance of the DlBF and TBF. Finally, as a result of the simulations, we observe that the original analytical estimate for the deletable probability of DlBF tends to overestimate the probability.","PeriodicalId":112723,"journal":{"name":"2019 European Conference on Networks and Communications (EuCNC)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131294501","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 band has a high potential for near future short range, high data rate applications due to large spectral resources and reasonable path loss. The frequencies around 300 GHz are among the first ones where the molecular absorption loss becomes a significant factor. This loss increases exponentially with the distance and is not a major issue at short distances (few meters), but entirely blocks signals over large distances. Modeling of the molecular absorption loss is relatively straightforward, but requires large numbers of parameters from spectroscopic databases. This paper derives a simplified polynomial absorption loss model for the major absorption lines. This extends and gives more accurate absorption loss values in comparison to the existing ITU-R absorption loss models. The simplified polynomial expressions by ITU-R are mostly limited to about 350 GHz frequency, although being rather accurate up to about 400 GHz. This paper gives a simpler and more accurate absorption loss model to those bands.
