Performance analysis of social-aware content-based opportunistic routing protocol on MANET based on DTN 基于DTN的基于社会感知内容的MANET机会路由协议性能分析
I. G. A. S. Negara, L. V. Yovita, T. Wibowo
Nowadays, almost all telecommunication devices use TCP/IP to communicate with each other. However, it is difficult for MANET to support the type of end-to-end connectivity required by TCP/IP-based communications due to disruptions, frequent topology changes and network partitions caused by the movement of the nodes. DTN is an emerging paradigm in the telecommunication network which is able to provides data communication in areas with intermittent connectivity, long delay communication, and high error rate. SCORP (Social-aware Content-based Opportunistic Routing Protocol) is a routing protocol on DTN which works by taking account of social proximity and content interests on each node before replicating the message to the other node in order to improve the ability of network in sending messages. In this paper, we show the performance analysis and the advantages of SCORP compared with Epidemic and Spray and Wait under different number of buffer size and nodes on the network. We also show the impact of different number and types of interests per group of nodes on the performance of SCORP. We use Braga and Asia-Afrika area in Bandung as the simulation area in The ONE Simulator.
如今,几乎所有的电信设备都使用TCP/IP进行通信。然而,由于节点移动引起的中断、频繁的拓扑变化和网络分区,MANET很难支持基于TCP/ ip通信所需的端到端连接类型。DTN是一种新兴的电信网络模式,它能够在间歇性连接、长时延通信和高错误率的领域提供数据通信。SCORP (social -aware content -based Opportunistic Routing Protocol)是一种基于DTN的路由协议,它在将消息复制到另一个节点之前,先考虑每个节点的社交接近度和内容兴趣,以提高网络发送消息的能力。本文给出了SCORP在不同缓冲区大小和网络节点数下的性能分析以及与Epidemic和Spray and Wait相比的优势。我们还展示了每组节点不同数量和类型的兴趣对SCORP性能的影响。我们在the ONE Simulator中使用Braga和万隆的亚非地区作为模拟区域。

Fiber optic has an important role in the development of telecommunications infrastructure in Indonesia. Better network performance and quality of the speed that offered by fiber optic can support the data requirement which continues to increase every year. In Indonesia, Fiber Optics is used as the primary network infrastructure Backbone and Access and still continue to develop the fiber optic network in Indonesia. Therefore, the process of reporting, controlling and monitoring are imperative for network deployment of fiber optic network by using an application system to be more efficient and accelerate the decisionmaking process. In this study FOMApps is made, an android-based application that facilitates the requirements of monitoring, controlling and reporting the fiber optic project between the Government and fiber optic deployment provider. In particular, FOMApps include different reporting formats for each type of job. The test results of reporting system Optical Fiber Cable (Outside Plant) has a speed in delivering the report amounted to 257.516 seconds. So from the results that are obtained, the application is feasible for use in reporting the deployment of Outside Plant Fiber Optic. With the existence of this application, w e expect the process of controlling and monitoring between the Government and fiber optic deployments providers are achieved.
光纤在印尼电信基础设施的发展中发挥着重要作用。光纤提供的更好的网络性能和速度质量可以支持每年持续增长的数据需求。在印度尼西亚,光纤被用作主要的网络基础设施骨干网和接入点,并且仍在继续发展印度尼西亚的光纤网络。因此,利用应用系统对光纤网络的网络部署进行报告、控制和监控是提高效率和加快决策过程的必要条件。在本研究中,FOMApps是一个基于android的应用程序,它促进了政府和光纤部署提供商之间对光纤项目的监测、控制和报告需求。特别是,FOMApps为每种类型的作业包含不同的报告格式。报告系统光纤光缆(厂外)的测试结果,报告传送速度达257.516秒。因此,从所获得的结果来看,该应用程序用于报告植物外光纤的部署是可行的。由于该应用程序的存在,我们期望实现政府和光纤部署提供商之间的控制和监测过程。

Skewing and notching configurations for torque pulsation minimization in spoke-type interior permanent magnet motors 轮辐式内置永磁电机中扭矩脉动最小化的倾斜和缺口结构
E. Sulaiman, G. M. Romalan, N. A. Halim
Interior permanent magnet (IPM) motors become popular and commonly used in industry and domestic applications. One of them is spoke-type IPM. Spoke-type interior permanent magnet (IPM) machines are an attractive topology for high-performance electric motors. In most of the applications, the high strength of permanent magnets causes the undesirable effects of high cogging torque that can aggravate motor performance. Consequently, the reduction of cogging torque becomes an important topic in IPM motor. In this paper, to minimize the effect of cogging torque in IPM motor, two common techniques for cogging torque reduction such as skewing, and notching, has been analyzed in order to compare the cogging torque, back EMF and efficiency effect. 3D finite element analysis (FEA) by JMAG software is carried out for each technique. The results showed the reduction of cogging torque up to 98.6%, followed by 81.84%, 45.24% and 36.79% compared to the initial model design.
内部永磁(IPM)电机在工业和家庭应用中越来越受欢迎和广泛使用。其中之一是辐条式IPM。辐条式内嵌永磁(IPM)电机是高性能电机的一种有吸引力的拓扑结构。在大多数应用中,永磁体的高强度会导致高齿槽转矩的不良影响,从而恶化电机性能。因此,减小齿槽转矩成为IPM电机研究的一个重要课题。为了最大限度地减少齿槽转矩对IPM电机的影响,本文分析了两种常用的齿槽转矩减小技术,即斜切和切槽,以比较齿槽转矩、反电动势和效率影响。采用JMAG软件对各工艺进行了三维有限元分析。结果表明,与初始模型设计相比,齿槽转矩减小幅度分别为98.6%、81.84%、45.24%和36.79%。

E. Sulaiman, M. Omar, Liyana Mohamed Ishak
Hybrid Permanent Magnet Flux Switching Machine (HPMFSM) is a machine that uses two permanent magnets which are Ferrite Permanent Magnet (FPM) and Rare Earth Permanent Magnet (REPM). The REPM had being implemented widely in HEV nowadays. So, HPMFSM is created in order to reduce the volume of REPM itself. Three designs had created which are PM, PMH and SMH design. PM only consist of REPM, meanwhile PMH and SMH consist REPM and FPM. The difference of the PMH and SMH is the arrangement of permanent magnet. The machine can generate higher performance by combining FPM and REPM. The HPMFSM load analysis is conducted in order to verify the 7pole/6slot/7pole HPMFSM machine performances. Through the analysis, the performances of the machine are able to identify. The PMH design can compete with the PM design which gives higher torque density.
混合永磁通磁开关机(HPMFSM)是一种采用铁氧体永磁(FPM)和稀土永磁(REPM)两种永磁体的机器。目前,REPM已在HEV中得到了广泛的应用。因此,创建HPMFSM是为了减少REPM本身的体积。提出了PM、PMH和SMH三种设计方案。PM仅由REPM组成,PMH和SMH由REPM和FPM组成。PMH和SMH的不同之处在于永磁体的排列。通过FPM和REPM的结合,机器可以产生更高的性能。为了验证7极/6槽/7极HPMFSM的性能,进行了HPMFSM负载分析。通过分析,对机器的性能进行了识别。PMH设计可以与提供更高扭矩密度的PM设计竞争。

Inter-regional voice bandwidth calculation on IMS network IMS网络跨区域语音带宽计算
D. D. Sanjoyo, R. Munadi, L. F. Adjie, Tjahjo Adiprabowo
The inter-regional telecommunication network design in Indonesia is strongly influenced by the bandwidth of Voice over Internet Protocol (VoIP), where 40% of the national bandwidth is used to pass voice communication. Indonesia region is divided into seven regional areas; each of these is supported by two IMS Cores, which serves as the active core and the stand-by core. Regionals are interconnected with each other through an IP backbone network. It serves to get through a number of bandwidth when there is communication between the regionals. The bandwidth requirement can be obtained through the calculation of traffic in regional, inter-regional traffic, and along with demographic data as well as the number of customers who have registered on the IMS network. Since voice traffic is passed in IP networks, the voice bandwidth is calculated in bps (bits per second) units. Standard voice codecs used for the conversion are G.711 and G.729. The national bandwidth load for voice traffic on the IMS backbone network can be obtained using mathematical calculations. The results of the calculation are presented in bandwidth matrices of the seven regions traffic for each standard (G.711 and G.729).
印度尼西亚的跨区域电信网络设计受到互联网语音协议(VoIP)带宽的强烈影响,其中40%的国家带宽用于传递语音通信。印尼地区分为七个大区;每一个都由两个IMS核心支持,分别作为活动核心和备用核心。各地区之间通过IP骨干网相互连接。当区域之间有通信时,它的作用是通过一些带宽。带宽需求可以通过计算区域流量、区域间流量、人口统计数据以及在IMS网络上注册的客户数量来获得。由于语音流量在IP网络中传递,因此语音带宽以bps(比特每秒)为单位计算。用于转换的标准语音编解码器是G.711和G.729。通过数学计算,可以得到IMS骨干网话音业务的全国带宽负荷。计算结果以每个标准(G.711和G.729)的7个区域流量的带宽矩阵表示。

Modified Wilkinson Power Divider 1 to 4 at S-band as the part of smart antenna for satellite tracking, telemetry, and command subsystem 改进的威尔金森功率分压器1至4在s波段作为智能天线的一部分,用于卫星跟踪,遥测和指挥子系统
Christian Mahardika, B. S. Nugroho, Budi Syihabuddin, A. D. Prasetyo, D. A. Nurmantris
Changing the value of current amplitude, phase or distance between antenna can make different radiation pattern in antenna array system. Using those principles, a smart antenna system can be made by using butler matrix which has configuration consisting of multiple power combiner and phase shifter. The power divider can be used in order to change the input values (current input) for each port of the buttler matrix. So we didn't need many signal generator to supply input of butler matrix (example for 4×4 butler matrix we just put 1 to 4 Power Divider on input port of butler matrix). A power divider has been designed in this research to support the smart antenna system for satellite tracking, telemetry, and command (TT&C). This research designed the modified Wilkinson Power Divider 3 port to be 5 ports with 4 output ports which can work at a frequency of 2.3-2.45 GHz with the insertion of each port is <; -8 dB, the maximum value theoretically amounted to -6 dB. This is because the power divider works by dividing power into 1:4 ratio.
在天线阵系统中,改变电流的幅值、相位或天线之间的距离可以产生不同的辐射方向图。利用这些原理,利用管家矩阵构成智能天线系统,管家矩阵由多个功率合成器和移相器组成。功率分配器可以用来改变每个端口的输入值(电流输入)。因此,我们不需要许多信号发生器来提供管家矩阵的输入(例如4×4管家矩阵,我们只需在管家矩阵的输入端口上放置1到4个功率分压器)。本研究设计了一种功率分配器,以支持用于卫星跟踪、遥测和指挥(TT&C)的智能天线系统。本研究将改进的威尔金森功率分配器3端口设计为5个端口,4个输出端口,工作频率为2.3-2.45 GHz,每个端口插入<;- 8db,理论上最大值为- 6db。这是因为功率分配器的工作原理是将功率分成1:4的比例。

So we didn't need many signal generator to supply input of butler matrix (example for 4×4 butler matrix we just put 1 to 4 Power Divider on input port of butler matrix). A power divider has been designed in this research to support the smart antenna system for satellite tracking, telemetry, and command (TT&C). This research designed the modified Wilkinson Power Divider 3 port to be 5 ports with 4 output ports which can work at a frequency of 2.3-2.45 GHz with the insertion of each port is <; -8 dB, the maximum value theoretically amounted to -6 dB. This is because the power divider works by dividing power into 1:4 ratio.","PeriodicalId":431878,"journal":{"name":"2016 International Conference on Control, Electronics, Renewable Energy and Communications (ICCEREC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128826968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Digital image steganography with encryption based on rubik's cube principle 基于魔方原理的数字图像隐写加密
Sevierda Raniprima, Bambang Hidayat, N. Andini
Information exchange between sender and receiver becomes very fast and easy. The quality of message transmission, especially the security, must be noticed. Data hiding is important for securing message. It can be done using cryptography and steganography. This paper describes the result of investigation on image steganography system using secret grayscale image and RGB image as a cover. Before the secret image is embedded into the cover, the encryption process is done to provide a more reliable security. The encryption method used is based on rubik's cube principle, by moving the pixels position in a digital image. The steganography uses LSB substitution method that works in spatial domain. The objective of this scheme is to obtain a high quality hidden secret image in order to keep message secret. Finally, effectiveness of the proposed scheme is tested using histogram analysis, Avalanche effect, Brute-Force attack, visual attack, statistical attack of Chi-Square analysis, and size and embedding position differences analysis.
发送者和接收者之间的信息交换变得非常快速和容易。消息的传输质量,尤其是安全性,必须引起人们的注意。数据隐藏对于保护消息非常重要。它可以使用密码术和隐写术来完成。本文介绍了以秘密灰度图像和RGB图像为封面的图像隐写系统的研究结果。在秘密图像嵌入封面之前,加密过程已经完成,以提供更可靠的安全性。使用的加密方法是基于魔方原理,通过移动像素在数字图像中的位置。隐写采用的是在空间域中工作的LSB替代方法。该方案的目标是获得高质量的隐藏秘密图像,以保证消息的保密性。最后,通过直方图分析、雪崩效应、暴力攻击、视觉攻击、卡方分析的统计攻击以及大小和嵌入位置差异分析来验证该方案的有效性。
