The main objective of deploying Vehicular Ad-hoc Network (VANET) is to reduce the accidents level by providing traffic information to the driver to drive safely. Since VANET supports emergency real-time applications and deals with human life critical information, the security of VANET becomes one of the most critical issues. Numbers of secure VANET protocols have been proposed to solve this issue, but privacy has received less attention. In this paper, we proposed a secure VANET protocol which guarantees privacy and authentication via hierarchical pseudonyms with blind signature. Furthermore, we analyzed our protocol using Scyther Tool for protocol verification. The result shows that our protocol achieved the security claims.

This paper presents a wideband C-shaped patch antenna for LibyaSat-1. The two parallel slots of the upper C-shaped path are incorporated to generate a second resonant frequency and hence broaden bandwidth. The folded patch technique is used to reduce the coaxial probe length and inductance at the feed section. In addition, the Quasi Newton method is used to achieve an operating frequency of 2.215 GHz (S-band). Our simulation results show that the antenna achieves a −10-dB impedance bandwidth of 1550 MHz (2.00–3.55 GHz), and has a total gain of 6.45 dB at 2.215GHz.

Device-to-device (D2D) communication was introduced as one of the technologies expected to tackle the increasing demand for high data rates and the growing usage of smartphones with its consequent traffic volumes. Interference is the main problem from which D2D suffers, for which several schedulers were developed. Most of the current scheduling techniques show a significant level of complexity. One way to reduce interference for D2D is to exclude some devices in a cell from D2D communication. In this paper we propose the use of a simple noise thresholding regardless of the scheduler. A device can take part in a D2D connection only if after their transmission, the value of interference in the cell remains below a specific threshold. This paper presents a comparison between the throughput of D2D devices for the case when devices are excluded based on the noise level in a cell compared to the case where no exclusion is made. In a previous work it was found that the probability distribution of device locations significantly impacted throughput. The results from two different probability distributions are presented in this paper. This study shows that when an exclusive approach is taken, the throughput per D2D device can be probabilistically guaranteed.

This paper proposes a method of transformation of time Petri net into Promela in order to verify their behavioral properties of the timed systems. The concurrent systems, with time attributes on transactions, are typically written in time Petri net. For quantitative and qualitative analysis of their properties, these time Petri net would be transformed into Promela beforehand. We also propose the linear temporal formula to specify the correctness properties. The proposed transforming method copes with the representation of both Petri net structure and its dynamic behavior. The token flows in time Petri net are modelled into Promela code, hence the implicit dynamic behavior would be practically described in the model. The resulting Promela code is simulated and verified by SPIN tool and reveals that not only the time related behaviors would be evaluated, but also the qualitative properties, such as safety and liveness.

In the digital era of information technology today, information technology services are needed by all parties ranging from lay people, educational organizations, government organizations, and companies. The current digital growth has resulted in data information services being used as a distribution network that is essentially more common than communication networks and solving distribution problems of complex point-to-point communication protocols and error-prone. One of them is Named Data Networking (NDN), which is a future network technology that is present in helping the effectiveness of network usage in contemporary Internet architecture such as Internet Protocol (IP). With the development of telecommunication technology in Indonesia, through the Ministry of Communication and Information has issued a project Palapa Ring backbone network which is one of the concerns of the Government of the Republic of Indonesia to build the availability of fiber-optic network as the backbone of the national telecommunication network that connects all regions in Indonesia. In this paper will discuss how the effect of changing the size of the content store in the NDN networks using the topology Palapa ring by measuring some parameters such as the value of the dropped package or the value of a delay package.

Soft Frequency Reuse (SFR) has become one of most important enablers for wireless systems, especially orthogonal frequency division multiplexing (OFDM) based ones, to achieve high data-rate communications. To resolve inter-cell interference (ICI), inter-cell interference coordination (ICIC) technique such as Soft Frequency reuse (SFR) can be used. SFR use dynamic power ratio to mitigate ICI without compromising spectrum efficiency. In this paper SFR power ratio is evaluated by simulating throughput value. Simulation result shows that the power ratio control in SFR can effectively optimizing cell performance.

A half bowtie antenna was designed to facilitate the application of direction finding in FM Radio Frequency (88–108 MHz) and UHF television reception (500–600 MHz). A slot augmenting was applied at the middle of the antenna to make a better performance on return loss of both bandwidths. Antenna size minimizing was applied to make it easier to manufacture and lower on the budget. Antenna characteristics were analyzed by simulation. Then, four antennas were manufactured and measured. The measured results showed that the proposed antenna had an impedance bandwidth from 88–108 MHz and 500–600 MHz with return loss smaller than −10 dB. The antenna achieves a compact size which is 17.6% smaller than its theory size. Furthermore, signal receiving from the transmitting artificial antenna experiment demonstrates that the antenna can be well suitable for determining the Direction of Arrival (DoA).

A satellite is a vital infrastructure for national security, national telecommunications infrastructure, broadcasting services, and earth observation purposes. Indonesia has used satellites since 1976 for domestic communications purposes. As a maritime and an archipelagic country, satellite communications is very useful with Indonesia's condition. Therefore, it is important to develop new policies and regulations to increase the number of national satellite filings and orbital slots. Indonesia's current government has a Nawacita program that should be supported by the national telecommunications infrastructure, especially in using satellites. The Indonesian satellite market shows a supply and demand gap condition, where most of the satellite usage is provided by foreign satellites. There are 36 foreign satellites used in Indonesia, which is served by 16 countries. Currently, Indonesia uses a foreign satellite capacity equal to 5 to 6 foreign satellites. Based on interviews conducted on several key respondents, new policies and regulations are needed to support national orbital slots and set up new entities to manage national satellite filings. Indonesia will significantly increase its satellite use in line with the deployment of 3T (Terluar, Terdepan, dan Tertinggal) areas, and in support of economic activities such as e-commerce and digital economic aspects. If the cost of leasing foreign satellite usage can be decreased, Indonesia can save more in expenditures. These savings can be used to deploy national satellites. Based on the results of interviews conducted, the problems with Indonesian satellite operators include: a lag of investment, an inward looking orientation, and too many national satellite operators with minimum real satellites in operation. According to the respondents, Indonesian satellite deployment can be done by a special board that is called Badan Layanan Umum (BLU). Having direct government to government (G to G) cooperation between Indonesia and other countries in the satellite and orbital slot usage agreement is a strategy to increase the satellite capacity. Once Indonesia and other countries reach a consensus in using satellite filings, it can be managed by BLU. BLU will then make a satellite design until the satellite launching. Satellite operators will be selected by BLU through a tender, and the winner of the tender will deliver the satellite capacity to all users in terms of business to business.
卫星是国家安全、国家电信基础设施、广播服务和地球观测目的的重要基础设施。印度尼西亚自1976年以来一直将卫星用于国内通信目的。作为一个海洋和群岛国家，卫星通信对印度尼西亚的情况非常有用。因此，制定新的政策法规来增加国家卫星申报和轨道槽数是非常重要的。印尼现任政府有一个纳瓦奇塔计划，应该得到国家电信基础设施的支持，特别是在使用卫星方面。印度尼西亚卫星市场呈现供需缺口状况，大部分卫星使用是由外国卫星提供的。印尼有36颗外国卫星，由16个国家提供服务。目前，印度尼西亚使用的外国卫星容量相当于5至6颗外国卫星。根据对几位主要答复者进行的访谈，需要新的政策和法规来支持国家轨道槽位，并建立新的实体来管理国家卫星申报。印度尼西亚将根据3T (Terluar, Terdepan, dan Tertinggal)地区的部署大幅增加其卫星使用，并支持电子商务和数字经济等经济活动。如果可以降低租用外国卫星的费用，印度尼西亚就可以节省更多的开支。节省下来的费用可用于部署国家卫星。根据访谈的结果，印尼卫星营运商的问题包括:投资滞后、向内看、国家卫星营运商太多，实际营运的卫星却最少。根据受访者的说法，印尼的卫星部署可以由一个名为Badan Layanan Umum (BLU)的特别委员会来完成。印度尼西亚与其他国家在卫星和轨道槽使用协议方面进行直接政府对政府(G对G)合作是增加卫星容量的一项战略。一旦印度尼西亚和其他国家在使用卫星申请方面达成共识，就可以由BLU管理。然后，BLU将在卫星发射之前进行卫星设计。BLU将通过招标选择卫星运营商，中标企业将以企业对企业的方式向所有用户交付卫星容量。

We consider the sum rate achievable throughput between different heuristic coordinated beamforming scenarios, which are the maximum ratio transmission (MRT), zero-forcing beamforming (ZFBF) and the maximum signal-to-leakage-and-noise ratio maximizing beamforming (SLNR-MAX). We assume there is a fixed number of high-altitude-platforms (HAPs) providing simultaneously high-data rate internet access on a fixed number of high-speed trains (HST). We consider the scenarios where the trains are separated apart and crossing each other. Simulation results show that the SLNR-MAX beamforming outperforms the ZFBF and MRT schemes.

Simulation results show that the SLNR-MAX beamforming outperforms the ZFBF and MRT schemes.","PeriodicalId":271883,"journal":{"name":"2017 11th International Conference on Telecommunication Systems Services and Applications (TSSA)","volume":"433 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114665319","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}
