Designing, dimensioning, and optimization of communica-tion networks have been an inseparable part of the develop-ment of telecommunications and information infrastructurefrom the very beginning of their existence.These networkingproblems have changed substantially over the recent yearsas a result of the changes in the telecommunications areatowards 4G/5G wireless multiservice networks and mobilecommunications, as well as networks convergence. Each andevery newly introduced type of a radio network technologyis followed by a substantial increase in both the numberand the complexity of problems that need to be resolved bytheoreticians and engineers.
No matter what these developing changes may bring, theessential tasks for 4G/5G wireless communication networksremain the same: (1) to develop new technologies offeringincreasing radio network capacity, (2) to determine and eval-uate the relationship between the quality of service (qualityof experience) parameters and the parameters characterizingtraffic sources (services), (3) to control and optimize theusage of radio network resources, and (4) to enhance thecapabilities of data transport, transmission, and receptionbetween end users and the core network.These tasks providea basis for developing engineering algorithms and tools usedfor designing, analysis, dimensioning, and optimization ofwireless systems and networks.
The objective of this special issue, containing 11 papersselected from submissions to the open call for papers, was tobring together the state-of-the-art research contributions that
address challenges in 4G/5G radio networks design, dimen-sioning, and optimization.
In the paper “Energy Efficiency and Capacity Tradeoffin Cloud Radio Access Network of High-Speed Railways,” S.Li et al. propose a predictable path loss based time domainpower allocation (PPTPA) method to improve energy effi-ciency performance of High-Speed Railways (HSR) commu-nication system. The authors assumed in the paper that inthe future the communication system for HSR will be basedon cloud radio access network. The optimization problemformulated in the paper is based on joint energy efficiencyand services transmission delay constraints.The effectivenessof the proposed power allocation algorithm was validatedin the paper by HSR channel measurement trace basedemulation results and extensive simulation results.
The paper “Mobile Network Planning Tool Based onDataAnalytics” by J.Moysen et al. describes the tool which is basedon the information available in the network and allow prop-erly deploying, configuring, and optimizing network nodes.In the tool two optimization techniques, that is, MachineLearning (ML) and Genetic Algorithms (GAs), are used. Inorder to evaluate the proposed tools two case studies werediscussed: for the small cell deployment in a dense indoorscenario and for a detected fault in a macrocell network. Asimulation-based performance analysis of the proposed toolwas carried out over the Ns-3 LTE-EPC Network Simulator.
In the paper “Virtualized ANR to Manage Resources forOptimization of Neighbour Cell Lists in 5G Mobile Wireless

Networks” by Y. Shin and S. Kim the network function vir-tualization (NFV) for Automatic Neighbour Relation (ANR)was proposed. The author assumed that in 5G networksan increase of simultaneous handover and the change ofneighbour cell lists will be very quickly and the traditionalANR function has neighbour removal function but it doesnot consider fast changes in the neighbour list. Therefore thenew ANR-virtual network function (ANR-VNF) is proposedin the paper. The experiments for the studied strategy ofANR were executed in practice by using LTE core network(Amarisoft LTE-100 Platform).
In the paper “A Categorized Resource Sharing Mech-anism for Device-to-Device Communications in CellularNetworks” by J. Chen et al., the resource sharing mechanismfor device-to-device (D2D) communications is studied. Inthe proposed solution the D2D pairs are divided into threegroups based on comparison of theminimum transmit powerwith the maximum transmit power of each cellular UE.The mechanism studied in the paper enables multiple D2Dpairs in the second group to share the resource with cellularuser equipment (UE) simultaneously and D2D pairs in thefirst group and the third group share resource with cellularUEs based on the transmit power minimization principle.Results of simulations conducted by the authors show that theproposed scheme allows obtaining a relatively higher networkthroughput and a lower transmit power of the D2D system.
The paper by P. Sroka and A. Kliks, entitled “PlayingRadio Resource Management Games in Dense Wireless5G Networks” proposes an efficient and flexible tool forinterference mitigation in ultradense heterogeneous cellular5G networks. Authors study, via simulation, various game-theory based algorithms which concentrate on the opti-mization of the overall base station energy consumption.Simulation results verify that the adopted game-theoreticalgorithms are very promising solutions for interferencemitigation outperforming the algorithm proposed for LTE-Advanced in terms of the achieved spectral efficiency.
The paper by S. Hanczewski et al. entitled “Convolu-tion Model of a Queueing System with the cFIFO ServiceDiscipline” proposes an approximate convolution modelof a multiservice queueing system that services a mixtureof independent multiservice Bernoulli-Poisson-Pascal callstreams under the continuous First-In-First-Out (cFIFO)service discipline. The accuracy of the proposed convolutionmodel is verified by simulation experiments for a number ofqueueing systems.
The paper by F. Alsewaidi et al. entitled “Enhancing RadioAccess Network Performance over LTE-A for Machine-to-Machine Communications under Massive Access” proposesthree methods to enhance RAN performance for Machine-to-Machine (M2M) communications over the LTE-A stan-dard. The first method employs a different value for thephysical Random Access Channel (RACH) configurationindex to increase random access opportunities. The sec-ond method addresses a heterogeneous network by usinga number of picocells to increase resources and offloadcontrol traffic from the macro base station.The third methodinvolves aggregation points and addresses their effect onRANperformance. The results presented in the paper confirmed
that the proposed methods improved RACH performance interms of access success probability and average delay.
The paper by J. Sae and J. Lempiainen, entitled “Main-tainingMobileNetworkCoverageAvailability inDisturbanceScenarios,” studies the case of disturbance and disasterscenarios in mobile networks. Authors perform varioussimulation scenarios under different network layouts withthe aim of maintaining the availability of cellular networksin disturbance scenarios. Simulation results show how themobile network availability duration can be sustained byselecting a set of evolved node B (eNB) sites to operateat a time and still maintain a reasonable service level andavailability in disturbance scenarios.
In the paper “Macrocell Protection Interference Align-ment in Two-Tier Downlink Heterogeneous Networks” by J.Seo et al., theMCP-IAmethod to limit interference problemsin two-tier (picocells and macrocells) MIMO networks waselaborated. Due to the proposed solution, the additional arrayand diversity gains, in comparison to the results obtained onthe basis of existing interference alignment solutions, can beobtained for the macro users. The performance of the pro-posed method was evaluated in a simulation environment, atthe link level as well as at the system.
The paper “LDPC Decoding on GPU for Mobile Device”by Y. Lu et al. proposed a software multicode word parallelLDPC decoder, exploiting OpenCL based graphics process-ing units built-in into mobile devices. Software realizationof LDPC decoding ensures a possibility of dynamic changeof code length, code rate, and the number of iterations, inorder to tune to networks’ conditions. The tests led in theexperimental test-bed confirmed high performance of theproposed solution and confirms a possibility of its applicationfor large file transmission and delay-sensitive services likevideo calling in mobile networks.
The paper “Latent Clustering Models for Outlier Identi-fication in Telecom Data” by Y. Ouyang et al. deals with theproblem of fast and robust identification of unexpected trafficstreams in high-speedmobile networks, generated in the caseof malicious attacks or technical problems. As the solutionto this problem, the authors selected an approach based onclustering models and proposed the application of GaussianProbabilistic Latent Semantic Analysis (GPLSA) and time-dependent GaussianMixture Models (timeGMM).The com-parison of the efficiency of the methods was performed in asimulation environment.
