Network emulators are often used tools for different kinds of experiments, for example testing network protocols and studying application behavior under certain network conditions. It is crucial for network emulators to work according to their specifications in order to ensure reliability and reproducibility of the performed experiments. This paper therefore evaluates the accuracy and performance of current well-established network emulators, including hardware and software solutions. The results show that no emulator reproduces all effects perfectly. Although the accuracy is acceptable in general, we finally analyzed strengths and weaknesses of the different solutions. Other researchers can use our measurement results to choose the right emulator for their experiments.

Monitoring of oilfield well-head installations can be enhanced by Quadcopters equipped with video cameras flying at low altitude. Backhaul of a video stream from a Quadcopter's camera takes place via WiMAX base-stations within the installation. This paper considers a problem that arises: Video stream interruption as a handover occurs between WiMAX base-stations. The paper presents a scheme for hard handover recovery during video streaming to a remote monitoring station. The selective Negative ACKnowledgment (NACK) scheme trades a reduced but acceptable video quality during handover for improved end-to-end latencies compared to unselective NACKs. Both forms of NACK (selective and unselective) promise better video quality (by several dB) than with UDP transport or traditional congestion-controlled streaming, which results in long delays during handovers.

With the exponential growth of video traffic over wireless networked and embedded devices such as mobile phones and sensors, mechanisms are needed to predict the perceptual quality of video in real time and with low complexity, based on which networking protocols can control video quality and optimize network resources to meet the quality of experience (QoE) requirements of users. This paper proposes an efficient and light-weight video quality prediction model through partial parsing of compressed video bitstreams. A set of features were introduced to reflect video content characteristics and distortions caused by compression and transmission. All the features can be obtained directly from the H.264/AVC compressed bitstream in parsing mode without decoding the pixel information in macroblocks. Based on these features, an artificial neural network model was trained for perceptual quality prediction. Evaluation results show that the proposed prediction model can achieve accurate prediction of perceptual video quality through low computation costs. Therefore, it is well-suited for real time networked video applications on embedded devices.

Advanced, dynamic spectrum management techniques are needed for frequency reuse in tiered and heterogeneous wireless networks. For reuse of transmission resources, feasibility in a power control sense is of prime interest. In this paper, it is shown that by transforming the signal to interference and noise ratio (SINR) to a power fraction, feasibility of resource reuse can be identified. The influence of maximum transmission powers and noise on feasibility are evaluated. It is motivated that a degree of spatial occupation can be defined with power fractions and that infeasibility occurs when the overall required occupation exceeds a finite value. Based on these findings, a system model is presented that can be used to identify communication pairs for feasible resource reuse.

Spatial modulation (SM) has recently drawn a great deal of attention, particularly due to the low complexity that it promises for both the transmitter and the receiver sides. However, this technique has a significant spectral efficiency loss with respect to spatial multiplexing (SMX) with the same number of transmit (Tx) antennas, and when the modulation order is increased to achieve the same spectral efficiency, it loses in terms of the bit error rate (BER). In this paper, a new type of SM (referred to as Enhanced SM) is proposed which increases the number of bits transmitted per channel use compared to conventional SM. Note that conventional MIσMO techniques including SMX and SM employ a fixed signal constellation. In our proposed technique, some information bits select not only the index(es) of the active antenna(s), but also the constellations to be transmitted from each of them. Both the closed-form analysis and the numerical results demonstrate that the proposed technique achieves better performance than conventional SM and that in most cases it also outperforms SMX.

Wireless data traffic is continuously increasing due to the steady rise in both connected device number and traffic per device. Wireless networks, traditionally confined below 6 gigahertz, are getting clogged and unable to satisfy the ever-increasing demands of its users. Already aware of this, telecommunications industry and academia have been working on solutions. One of the main methods for throughput increase is operation bandwidth expansion; however, sufficient spectrum is not available within the conventional frequencies. Following various considerations, 60 GHz industrial, scientific and medical radio band has been selected as the new spectrum to be utilized and wireless personal and local area network standards for the band are already completed. In line with the stated developments, this paper proposes the use of 60 GHz band for the fifth generation (5G) communication systems. After very briefly setting the scene of the current wireless communication networks, the physical layer properties of the 60 GHz band are presented. A representative indoor simulation between the fourth generation and proposed 5G cases is set and performed. The results are assessed and compared before concluding the paper.

Nanowireless electro-magnetic communication networks in the Terahertz band have raised interest in the networking community these very last years. However, if detailed studies have been published on analytical modelling of these networks, no simulation have been run to study in detail the characteristics of the transmission medium. We have designed Vouivre, a standalone nanowireless simulator, which is interfaced with two micro-robots simulator DPRSim and VisibleSim. This paper describes briefly Vouivre and presents first metrics of the communication channel using a communication paradigm called TS-OOK (Time Spread On-Off Keying).

In next generation cellular systems, femtocell technology has been emerged as one of the leading deployment strategies aiming for a better indoor coverage and “5-bar” signal strength. Although widely studied in the literature, mobility and handover managements in these networks remain as a technical challenge in need of effective solutions. Especially in challenging indoor environments which consist of several walls and other physical obstacles, unnecessary handovers caused by unpredictable path losses are triggered in many situations. In order to manage the misleading handover decisions caused by these challenging topological infrastructures, a spatial estimation can be implemented into the handover algorithm. With this motivation, in this paper, we propose a new handover algorithm based on path loss measurements. To minimize the number of unnecessary handovers not only the measured path loss but also spatially estimated path loss values are considered for handover decision. Since empirical path loss models estimate path loss based on the average measurements, these models may not be suitable for challenging femtocell deployments. In this paper, instead of using empirical path loss models, Kriging interpolation methods are used so as to spatially estimate path loss measurements. The simulation results show that the proposed algorithm can minimize unnecessary handovers and lower the ping-pong handover rate compared with conventional scheme in challenging indoor environments.

In this paper, we study the capacity of multiple-input multiple-output (MIMO) systems under the constraint that amplitude-limited inputs are employed. We compute the channel capacity for the special case of multiple-input single-output (MISO) channels, while we are only able to provide upper and lower bounds on the capacity of the general MIMO case. The bounds are derived by considering an equivalent channel via singular value decomposition, and by enlarging and reducing the corresponding feasible region of the channel input vector, for the upper and lower bounds, respectively. We analytically characterize the asymptotic behavior of the derived capacity upper and lower bounds for high and low noise levels, and study the gap between them. We further provide several numerical examples illustrating their computation.
