Abstract

At present, in the field of application of numerous IT, multi-core processors are widely used, the hardware development is much faster than the speed of software development. Multi-core processor software is using the design concept of single-core processor software, so this software is not high-performance and the performance processor is not fully played. This paper firstly introduces the traditional software design method based on multiple cores, and then points out two problems existing in it.To improve its efficiency, I propose a method called pipeline which can improve processor utilization and the throughput of a processor, at the same time, reduce the cost of the system. This method has been verified in the network packet processing. DOI : http://dx.doi.org/10.11591/telkomnika.v12i4.4811

Abstract

The idea of Internet of Things (IoT) based traffic management & routing solution for parking space is due to the vehicle parking has become major issue in urban areas. The growing number of vehicles has contributed to the traffic problem and vehicle parking issue nowadays. The main purpose of this project is to assist the user to locate the vacant parking space, which help to reduce time and fuel consumption on searching the parking space. This proposed system was used online system via website application, which assist people to find the available parking slot. In fact, the system counted the capacity of the available parking space and notified the user through the website application. Frankly, the system was equipped with an ultrasonic sensor, which acts as the detector that sent data to the microcontroller in order to update into UBIDOTS cloud server for data logger purposes. This system could lessen or solve the time management problem at the parking area, which user could save their time by checking the available parking slots in advance through the website application.

Abstract

Cyber security has become a critical priority for electric utilities. With the increase in the use of intelligent measuring devices like PMUs and more advanced communications and information technology in smart grid, the overall attack surface has increased. Cyber attacks against synchrophasor system critical infrastructure are detrimental to the functioning of the society as a whole. This paper presents the latest on cyber security of synchrophasor system in smart grid, specifically; it focuses on the deep understanding of the risk in terms of threats, vulnerabilities and consequences that arise from cyber attacks. Since the research on cyber security for the smart grid is still in its early stage, our objective is to provide an overview, analyze potential cyber security threats, and review existing security solutions in the Wide Area Monitoring System.

Abstract

Taking the botnet incident response plan decision-making as an example, we construct a new graph model to represent complex plan resolution domain by using action decomposition. In this model we introduced action layer, relation between subactions and decompose the complex incident response plan into many layers. This graphic model provides a powerful representing framework on the complex plan domain. By analyzing the decomposing method and the action node structure, we prove that the store space size of this graphic representation is not increased exponentially when the action node added. We present a quantitatively analyzing algorithm on the plan resolution domain. DOI: http://dx.doi.org/10.11591/telkomnika.v11i1.1869

Abstract

Unlike the shortest path is randomly chosen in the traditional shortest path routing strategy, a novel routing strategy to improve the network transportation capacity is proposed in this paper. According to the different characteristics of the nodes along actual paths, we specify the shortest paths of all pairs of nodes aiming at reducing the betweenness of those high-betweenness nodes. Simulations on both computer-generated and real-world networks show that the new routing strategy can enhance the network transportation capacity greatly. And it works better in those networks with the fuzzy community structure. DOI: http://dx.doi.org/10.11591/telkomnika.v11i10.2963

Abstract

A dual resonance reflectarray unit cell element has been proposed which evolved from a square patch element to enhance its bandwidth performance. A bend in the width of the element is used to modify its dimensions and surface currents for broadband operation. The results have been analyzed in the frequency band of 24 GHz to 28 GHz. Two different combinations of its dimensions are selected for the investigating of its various performance parameters. A maximum static phase range of 432° and 255° have been obtained with selected dimensions. The wide-band features of proposed unit cell element can be used particularly to design a broadband reflectarray antenna for future fast communication systems.

Abstract

There has been an increasing attentiveness in the uses of sensor networks. Because sensors are normally controlled in on-board power supply, proficient supervision of the network is essential in improving the life of the sensor. The majority research protocols objective at offering link breakage reducing and mitigating from the same. Yet, selecting the well-organized communication do all the beneficial to the transmission process thus demonstrating better improvement in the network performance. In this article, we propose Best Communication Node Election for well-organized Path in Flat Topology The main goal of this work is to choose the best data transmission node in flat topology for improve the multi hop routing. This scheme, the best communication node selection based on Path Metric and this Path Metric is measured by the packet obtained rate, dropped rate, latency rate and node energy. This scheme provide guarantees quality of Service in the network.

Abstract

This paper describes a development of an algorithm for assessing stand productivity by considering the stand variables. Forest stand productivity is one of the crucial information that required to establish the business plan for unit management at the beginning of forest planning activity. The main study objective is to find out the most significant and accurate variable combination to be used for assessing the forest stand productivity, as well as to develop productivity estimation model based on leaf area index. The study found the best stand variable combination in assessing stand productivity were density of poles (X2), volume of commercial tree having diameter at breast height (dbh) 20-40 cm (X16), basal area of commercial tree of dbh >40 cm (X20) with Kappa Accuracy of 90.56% for classifying into 5 stand productivity classes. It was recognized that the examined algorithm provides excellent accuracy of 100% when the stand productivity was classified into only 3 classes. The best model for assessing the stand productivity index with leaf area index is y = 0.6214x - 0.9928 with R2= 0.71, where y is productivity index and x is leaf area index.

Abstract

High voltage substations as pivotal sections of power network play an important role in power network because of supplying electrical energy for consumers. In recent years with increment of electricity consumption and complexity of power system, the substation stability and protection against various faults or overvoltages has been a big concern. Surge arresters as protective device has the responsibility of attenuating overvoltage due to lightning or switching occurring in transmission or distribution system. Absence or failure of arresters inside or near substations can lead to load interruption and great outage in the system. Therefore their presence is indispensable. Demonstrating the surge arresters presence necessity and evaluating their failure impact during normal operating condition and overvoltage in different scenarios of arrester location and lightning surge position in view point of EMTP simulation and reliability technique is the purpose of this paper.

Abstract

Traditional vehicle video monitoring system enjoys not only large data but also dispersion, so it is difficult to retrieve and network. Wireless intelligent video analysis system of  vehicle on DM6446 is designed to solve the problem. In which ARM side of DM6446 completes the main control of the system, then it calls intelligent video analysis algorithm in DSP side of DM6446 through the Codec Engine, which greatly improves the efficiency of the system, and the TCP/IP protocol controls data transmission in the WCDMA network. The monitoring display terminal gets video information by accessing the corresponding IP address. The experiment shows that the system designed realizes intelligent recognition of license plate and vehicle body color safely and reliably, and the wireless network is coherent. DOI: http://dx.doi.org/10.11591/telkomnika.v11i5.2477
