The performance of YouTube in mobile networks is crucial to network operators, who try to find a trade-off between cost-efficient handling of the huge traffic amounts and high perceived end-user Quality of Experience (QoE). This paper introduces YoMoApp (YouTube Performance Monitoring Application), an Android application, which passively monitors key performance indicators (KPIs) of YouTube adaptive video streaming on end-user smartphones. The monitored KPIs (i.e., player state/events, buffer, and video quality level) can be used to analyze the QoE of mobile YouTube video sessions. YoMoApp is a valuable tool to assess the performance of mobile networks with respect to YouTube traffic, as well as to develop optimizations and QoE models for mobile HTTP adaptive streaming. We test YoMoApp through real subjective QoE tests showing that the tool is accurate to capture the experience of end-users watching YouTube on smartphones.

5G mobile networks will very likely include features that allow for a dynamic spectrum access (DSA) in order to exploit spectrum holes of a primary system. The efficient utilization of spectrum holes with minimum impairment of the primary system requires a waveform with a very low adjacent channel leakage ratio as well as robustness to time and frequency offsets. One of the approaches for new waveforms is Generalized Frequency Division Multiplexing (GFDM), a digital multi-carrier transceiver concept that employs pulse shaping filters to provide control over the transmitted signal's spectral properties. In this paper we present experimental results that evaluate the impact of the new GFDM waveform on an existing 4G system. The 4G system was based on Eurecom's OpenAirInterface for the eNB and a commercial UE. The 5G system was emulated using the LabVIEW/PXI platform with corresponding RF adapter modules from National Instruments and TUD's GFDM implementation. The experimental results show that GFDM can be used with about 5 dB higher transmit power than a corresponding orthogonal frequency division multiplexing (OFDM) system, before any impact on the primary system is noticeable. The results from our real-time measurements were validated by simulations.

The lifetime of a wireless sensor network is the most important design parameter to take into account. Given the autonomous nature of the sensor nodes, this period is mainly related to their energy consumption. Hence, the high interest to evaluate through accurate and rapid simulations the energy consumption for this kind of networks. However, in the case of a network with several thousand nodes, the simulation time can be very slow and even impossible in some cases. In this paper, we present a new model for a parallel computing of energy consumption in wireless sensor networks. This model is combined with a discrete event simulation in a multi-agent environment and implemented on GPU architecture. The results show that the proposed model provides simulation times significantly faster than those obtained by the sequential model for large networks and for long simulations. This improvement is more significant if the processing on each node is very time consuming. Finally, the proposed model has been fully integrated and validated into the CupCarbon simulator.

In this paper we propose a queuing model for predicting behavior of an uncorrelated Rayleigh flat fading channel. Using the notion of Hyperexponential (HE) probability density function, we model a Rayleigh fading channel as a combination of a few parallel exponential processes in the form of G/HR/1 queue with well-defined service and waiting time distributions. We illustrate validity of our analytical model with some numerical results.

Forward error correction (FEC) is a method for error control of data transmission adopted in several mobile multicast standards. FEC is a feedback free error recovery method where the sender introduces redundant data in advance with the source data enabling the recipient to recover from different arbitrary packet losses. Recently, the adoption of FEC error control method has been boosted by the introduction of powerful Application Layer FEC (AL-FEC) codes i.e., RaptorQ codes. Furthermore, several works have emerged aiming to address the efficient application of AL-FEC protection introducing deterministic or randomized online algorithms. The investigation of AL-FEC application as primary or auxiliary error protection method over mobile multicast environments is a well investigated field. However, the opportunity of utilizing the AL-FEC over mobile unicast services as the only method for error control, replacing common feedback based methods that are now considered to be obsolete, is not yet examined. In this work we provide an analysis on the feasibility of AL-FEC protection over unicast delivery utilizing online algorithms on the application of AL-FEC codes with exceptional recovery performance.

The provisioning of e-health and specifically m-health services requires the usage of advanced and reliable communication techniques to offer acceptable Quality of Experience (QoE) for doctors in the transfer of biomedical data between involved parties (i.e. flawless, or almost flawless, and prompt enough delivery) using wired or wireless access networks. To overcome the restrictions of conventional communication systems and to address the challenges imposed by wireless/mobile multimedia transfer and adaptation for healthcare applications, the CONCERTO project proposes a cross-layer optimized architecture with all the needed critical building blocks integrated for medical media content fusion, delivery and access, even on the move in emergency contexts. This paper describes the proposed reference system architecture, presenting the developed components and mechanisms in a comprehensive way, depicting and clarifying the overall picture and highlighting the impact of the CONCERTO approach in the healthcare domain. The evaluation of the proposed system is carried out both via simulation analysis and, more importantly, via validation involving real medical staff.

Homogenous Poisson Point Process (HPPP) have been adopted as an efficient model for the spatial distribution of Device-to-Device (D2D) links in cellular networks. However, real D2D deployments are rarely uniform distributed. Recently, non-uniform random spatial models have been introduced for devices involved in direct communications. To limit the interference created by D2D users, and other base stations, typically power control is adopted counteracting the path loss and shadowing effects in each link. However this does not prevent cellular users from experiencing coverage limitation. In this paper we develop an analytical model to characterize the coverage probability of cellular networks in the presence of D2D links accounting for shadowing, power control and users random locations. We consider the deployment of base stations is based on a homogeneous PPP (HPPP), whereas D2D links on a non-homogeneous PPP (NHPPP). Finally, to validate our model, we compare our theoretical analysis with simulation results.

We present a general framework for studying a lattice construction approach, namely the elementary divisor construction (EDC), which shows its strength in improving the overall rate over the multiple access channels (MAC) with low computational cost. Then a soft detector is developed for lattice network relaying, based on the multilevel structure of EDC. This makes it possible to employ iterative decoding in lattice network coding, and hence to improve the reliability of decoding the linear combinations over the message space.

Cloud Radio Access Network (C-RAN) is receiving increasing attention not only within the research community but also from operators and standardization bodies. However, even a good technology will be deployed only if it is economically viable. In our previous work, for larger scale deployment we recommend to divide the area into multiple BBU Pools. In this paper we show how to optimally assign cells to different BBU Pools in such a scenario. By using Integer Linear Programming (ILP) method we derive engineering guidelines for minimizing the CAPital EXpenditure (CAPEX) of C-RAN deployment.

With the expected increase in data traffic by multiple hundred-folds in the coming years, future networks are likely to experience large densification of small cells, with or without detailed network planning, in order to increase the network capacity. The biggest challenge this densification brings along is very high interference. Thus there is an urgent need to develop strategies that could help in the first place to avoid such large interference in small cell clusters. In this paper, we propose a novel scheme for dynamic radio resource management in the downlink for a cluster of heavily overlapped small cells. The scheme proposes the use of jointly considering real time interference and traffic characteristics of the small cells in the cluster. It is observed that the proposed method comparing to full reuse or fractional frequency reuse, leverages the network performance in terms of mean user throughput and total number of satisfied users, achieving ≥95% of the data-rate demand, at relatively a lower scheduling overhead.
