3GPP New Radio (NR) air interface operating in a millimeter wave frequency band is expected to provide the main bearer service in the fifth generation (5G) mobile systems. 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.

A computational scheme of the finite element method (FEM) is presented that allows the solution of the eigenvalue problem for a SOODE with the known potential function using the ODPEVP and KANTBP 4M programs that implements FEM in the Fortran and Maple, respectively. 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.

The major strength of the smart city concept consists of an efficient gathering of the citizens data using the fast and reliable communication infrastructure and ICT integration of different municipality sectors. The introduction of smart city will allow the creation of sustainable economic development and high quality of life by improving the key areas, such as the economy, mobility, environment, people, living, and government. The use of 5G technology in the smart city concept will enhance performance and welfare; it will also reduce cost and resource consumption. The major benefit of the smart services is that they provide multi-tenancy, shared infrastructure, multi-service, context-aware adaptation and optimized QoS/QoE mechanism according to the service needed and the infrastructure state. In that way, these services will improve the quality of life for citizens and will deliver a better user experience.

Network Function Virtualization (NFV) provides mobile telecom operators with the capability to legacy mobile core functions in virtualize network entities VNFs. This allows to offer fine-grade on-demand network services due to dynamically change of the amount of resources which handle the user traffic. - scale in/out process. Virtualization helps to decrease the OPEX of operators, but it is important to find a tradeoff between legacy and virtualised entities to be able to provide services and meet the QoS. We consider the hybrid 5G EPC core which contains both legacy and virtualized entities. The virtualized resource allocation process follows the hysteretic algorithm. The EPC Core is modelled as a queuing model with dynamically changed number of servers.

The 5G technology requires the application of optical fiber in the access network. The chromatic dispersion in fiber causes distortion of transmitted signal. The dispersion can be compensated by digital optical filters. The physical size of the filters depends on the number of coefficients. It is proved that the minimum number of coefficients is limited by the physical characteristics of optical fiber and has a quadratic dependence on frequency band. An analytical equation for estimating the number of coefficients is proposed. And the method for decreasing the total number of coefficients is considered.

In critical infrastructures such as Smart Grids, reliability is crucial. 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.

Long end-to-end delays in interactive or live multimedia systems, as perceived by the users, impair the Quality of Experience and the task performance. Hence, developers are out to assess end-to-end delays for detecting and correcting defects. Measurements at lower system levels only (e.g., packet delay at the transport layer) are not sufficient as network delay does not include significant delays in higher layers (e.g., buffers or audio and video interfaces). This paper addresses these concerns and presents low-cost, portable, GPS-synchronized embedded devices to measure perceived end-to-end delays in geographically distributed multimedia systems at the accuracy of a few microseconds.
