In a SDN-based data center network, the controller used greatly affects the behavior of the network. In this paper, the observation is conducted to describe the effect of various link failure scenarios to data center network performance using the Ripl-POX controller. Results shown in this paper can be used as a consideration for both controller selection or building for managing the data center and switch replacement method selection. This paper shows the effect of one to three switches that is turned down simultaneously on overall bandwidth. The simulation is done on 4k-fat tree data center network on mininet environment with RipL-POX as controller.

In this paper, the outage probability performance of optical inter-platform link is analyzed. Atmospheric turbulence is one of the main impairment affecting the operation of optical inter platform link. An inter-HAP channel was modeled as a random process with log normal distribution. The outage probability expression is theoretically derived and numerical results are presented. The results illustrate the outage probability dependence on the power margin, turbulence strength, and propagation path length.

Fast Multigrid Poisson solvers have been considered essential for developing efficient numerical method solutions in diverse fields. In this paper, we compare fast and simple multigrid methods: V-Cycle, W-Cycle, and F-Cycle to solve Poisson Equation (PE) in polar plane coordinates. The solver is analysed toward different 2n + 1 grid sizes to evaluate its convergence properties, i.e. precision and accuracy, as compared to reference problem of cylindrical annulus. Each multigrid cycle is evaluated based on computation time, convergence error, and relative error. The results show that W-Cycle (γ = 4) gives more optimized solution as Poisson solver in comparison with the other multigrid methods.

In this paper we present the most implementable scheme for transmitting 19 channels electroencephalography (EEG) and speech signals simultaneously using a speech channel of telephony system. The proposed system works based on re-sampling, multiplexing and filtering concepts. Re-sampling is applied to adjust EEG sampling frequency such that appropriate with speech signal sampling frequency. The 19 channels are time multiplexed then mixed with the speech to produce a transmitting signal. In the receiver side, speech and EEG are separated by filtering. Based on simulation result in the noise environment, the proposed system has successfully separated the speech and the EEG signals. The correlation coefficient between the received signals after separation and the original ones are more than 0.8 for EEG and more than 0.7 for speech in 30 dB SNR. Moreover, the proposed system has high possibility to be implemented with low computational complexity.

In this paper the coverage and capacity of CDMA system is evaluated using admission and power control to serve for low to medium speed internet services, such as digital TV or film/video streaming in rural areas. One of the unique characteristics of CDMA system is that it is possible to trade off between capacity and its coverage, called the cell-breathing. Open loop and closed loop power control can be used to increase the capacity of CDMA system; while admission control can be applied to trade-off between its capacity and the coverage. Computer simulation was conducted to evaluate the power control performance in Rayleigh fading channel. Then semi-analytical evaluation was performed to obtain the coverage-capacity trade-off. The result shows that the capacity of CDMA systems increases when power control was employed. Numerical and semi analytical evaluation show that CDMA coverage and capacity can be traded-off to meet various demand of traffic capacity and cell coverage in rural environments.

Internet penetration in developing countries depend on a variety of factors, including the Gross Domestic Product (GDP), the density of telephone connections, and the density of personal computer users. Internet kiosks have been deployed in 21 rural ditrict areas of Garut Regency to facilitate internet access for local/district government as well as for the community who have no access to internet Each district was equiped with 10 PCs, a printer, a scanner, and an internet connection either using DSL or cellular access technology. The program was government sponsored through the Ministry of Communications and Information of the Republic of Indonesia. This program was also designed to provide education and training for the district internet kiosks operator as well as for the staffs of information technology at Garut Regency, on understanding, efficient use, management, maintenance, as well as the ethical/professional use of information to upgrade their skills. This study was then conducted to evaluate factors affecting internet penetration in rural areas of Garut Regency, West Java of Indonesia.

In OFDMA (Orthogonal Frequency Division Multiple Access) wireless system, environmental conditions and mobility of all users make the conditions of propagation of each user on all subcarriers changed at different times. Required radio resource allocation scheme that works with accurate, has a fairly low complexity and it is able to adapt to changing conditions. This research is to answer these issues by developing a new resource allocation scheme that is adaptive to changes in the channel, with the classification of some subcarriers into one chunk is based on the analysis of the constellation signal received on each subcarrier. We propose grouping some subcarriers into one chunk by using clustering concept, the algorithm chosen for the simplicity of the computing process is a K-Mean Clustering. The simulation results indicate that the resource allocation scheme that we have proposed give SSE (Sum Squared Error) improvement and can improve throughput when compared to the conventional scheme which uses clustering on the received signal level.

In this paper, we propose a smart home platform based on optimized wireless sensor network (WSN) protocol and scalable architecture. In this platform, system environment is divided into two main environments, indoor and outdoor. Outdoor environment uses internet-cloud system, while indoor environment uses WSN system. This scheme is also well known as Internet-of-Things (IoT) concept. Those two environments are connected to each other by using access point bridge. WSN system is established from efficient and scalable WSN components. Each component of WSN is designed to use an optimized protocol. WSN components are connected to each other in mesh topology in order to provide scalable architecture for further extension and changes. For outdoor environment, the existing internet-cloud system is used as infrastructure. Thus, this smart home platform can be monitored and controlled from smart phone, anytime and anywhere, as long as mobile data access is provided. For databasing implementation, SQLite database system is chosen because of its low cost and easy configuration. For system evaluation, several tests have been conducted to deliver the profile of proposed system.
