Compensating for high propagation losses by using high gain antennas at both user equipment † (UE) and access point (AP) sides these systems will greatly benefit from highly directional transmission serving unicast sessions. However, highly directional nature of NR communications may affect the conventional service procedures of multicast sessions in wireless networks as more than a single transmission may be required to serve UEs in the same multicast group. Accounting for random resource requirements induced by locations of UEs as well as human blockage phenomenon, we develop a model for performance analysis of 5G NR systems serving a mixture of unicast and multicast sessions. The main performance metrics of interest are drop probabilities of unicast and multicast sessions. The proposed model, complemented with antenna models and beam-steering procedure, can be further used to determine optimal AP intersite distance for 3GPP NR systems.","PeriodicalId":211042,"journal":{"name":"2018 10th International Congress on Ultra Modern Telecommunications and Control Systems and Workshops (ICUMT)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115415477","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}

Numerical analysis of the solution using the KANTBP 4M program is performed for the SOODE exact solvable eigenvalue problem. The discrete energy eigenvalues and eigenfunctions are analyzed for vibrational and rotational states of the diatomic beryllium molecule solving the eigenvalue problem for the SOODE numerically with the table-valued potential function approximated by interpolation Lagrange and Hermite polynomials and its asymptotic expansion for large values of the independent variable specified as Fortran function. The efficacy of the programs is demonstrated by the calculations of twelve eigenenergies of vibrational bound states with the required accuracy, in comparison with those known from literature, and the vibrational-rotational spectrum of the diatomic beryllium molecule.","PeriodicalId":211042,"journal":{"name":"2018 10th International Congress on Ultra Modern Telecommunications and Control Systems and Workshops (ICUMT)","volume":"5 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129215210","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}

Traditionally, this is achieved via redundant devices and switch-over functionality. Existing solutions often handle redundancy on the application layer, which can be complex to install and maintain. This paper presents a novel and generic approach to provide redundancy for Smart Grids via software defined networking (SDN). Existing approaches of utilizing SDN in Smart Grids mainly focus on replacing technologies like Multiprotocol Label Switching (MPLS) and Virtual Local Area Networks (VLANs) to reduce configuration effort and increase network reliability. The proposed concept however aims to simplify control infrastructure redundancy setup and to increase flexibility. This is achieved by moving the redundancy logic from the application to the network, creating an application-agnostic solution to manage redundancy transparently across communication layers. Especially in scenarios with interruption-tolerant application-layer protocols and policies, benefits like reduced costs and additional configuration options are expected.","PeriodicalId":211042,"journal":{"name":"2018 10th International Congress on Ultra Modern Telecommunications and Control Systems and Workshops (ICUMT)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131938867","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}
