Abstract

TCP mempunyai banyak jenis pengembangan. Untuk jaringan dengan delay tinggi seperti seluler dan satelit seperti HSDPA maka TCP Westwood sering dipakai untuk protokol transport. Varian dari Westwood sendiri yaitu Westwood+ mempunyai kelebihan karena bersifat adaptif dalam menghadapi jaringan dengan loss tinggi. Pada linux kernel 2.6 TCP westwood sudah tersedia dan tinggal diaktivasi. TCP westwood+ sendiri mempunyai beberapa parameter diantaranya increment factor yang akan dipakai pada saat fase congestion avoidance pada algoritma Additive Increase. Secara default increment factor bernilai 1 dan bisa diubah. Pada makalah ini diujicobakan mengubah nilai increment factor tadi dan melihat pengaruhnya pada throughput. Dari hasil simulasi pada Network Simulator 2 bisa disimpulkan bahwa jika kita mengubah nilai increment factor tersebut pada jaringan bottleneck dengan nilai sembarang x2 dengan x2 diantara 0 sampai 1 maka pada throughput yang dihasilkan ternyata relatif sebanding dengan nilai x. pada kondisi bottleneck ternyata pengaturan besar throughput pada TCP Westwood+ bisa dilakukan dengan mengganti nilai increment factor dengan nilai tertentu sedangkan pada kondisi yang longgar atau traffik rendah maka perilaku throughput akan sama.

Abstract

Selama ini untuk menghidupkan kendaraan seseorang harus menggunakan sebuah kunci, sehingga untuk mengakses banyak kendaraan harus digunakan banyak kunci yang berbeda. Namun jika handphone dijadikan kunci elektronik, tentunya semua kunci tersebut tidak dibutuhkan lagi, karena satu handphone dapat mewakili kunci tersebut. Pada penelitian ini, sistem kunci elektronik menggunakan handphone sebagai kunci, dan sebuah mikrokontroler Arduino pada kendaraan sebagai penerima kontrol. Komunikasi antara handphone dan mikrokontroler menggunakan bluetooth. Komunikasi dengan bluetooth tersebut belum didukung dengan keamanan yang kuat. Bahkan ada yang menyatakan bahwa dukungan keamanan pada bluetooth sudah berhasil dipecahkan dan diserang. Oleh karena itu, penelitian ini dibuat untuk melengkapi aspek keamanan kunci elektronik dengan mengimplementasikan Advanced Encryption Standard (AES) dengan panjang kunci 128 bit, 192 bit, dan 256 bit. Hasil yang diperoleh dari penelitian ini adalah meningkatnya dukungan aspek keamanan yang diperoleh dari implementasi AES. Setelah dilakukan pengujian, total waktu eksekusi maksimum sistem kunci elektronik kendaraan yang telah dibuat sebesar 385 ms pada jarak 20 m. Lama waktu tersebut masih lebih rendah dibanding batas kenyamanan pengguna yaitu di bawah 1000 ms (Nielsen, 1993), sehingga sistem layak untuk diterapkan.

Abstract

Footstep recognition is relatively new biometrics and based on the learning of footsteps signals captured from people walking on the sensing area. The footstep signals classification process for security systems still has a low level of accuracy. Therefore, we need a classification system that has a high accuracy for security systems. Most systems are generally developed using geometric and holistic features but still provide high error rates. In this research, a new system is proposed by using the Mel Frequency Cepstral Coefficients (MFCCs) feature extraction, because it has a good linear frequency as a copycat of the human hearing system and Artificial Neural Network (ANN) as a classification algorithm because it has a good level of accuracy with a dataset of 500 recording footsteps. The classification results show that the proposed system can achieve the highest accuracy of validation loss value 57.3, Accuracy testing 92.0%, loss value 193.8, and accuracy training 100%, the accuracy results are an evaluation of the system in improving the foot signal recognition system for security systems in the smart home environment.

Abstract

Phishing is an activity carried out by phishers with the aim of stealing personal data of internet users such as user IDs, password, and banking account, that data will be used for their personal interests. Average internet user will be easily trapped by phishers due to the similarity of the websites they visit to the original websites. Because there are several attributes that must be considered, most of internet user finds it difficult to distinguish between an authentic website or not. There are many ways to detecting a phishing website, but the existing phishing website detection system is too time-consuming and very dependent on the database it has. In this research, the focus of Hadoop MapReduce is to quickly retrieve some of the attributes of a phishing website that has an important role in identifying a phishing website, and then informing to users whether the website is a phishing website or not.

Abstract

In the process of printing images, a high-quality plotter printer is required to obtain better printed images. This causes the costs incurred to purchase a plotter printer become even higher along with the quality of the printout. In addition, the use of original plotter printer ink is significantly more expensive than that of the non-original ink. Therefore, this paper proposes a pen based computer plotter printer design using the CoreXY framework. This framework is based on a 2D in-axis motion control technique using a single continuous belt for both axes. To evaluate the performance of the proposed design, the level precision for vector and raster modes are measured using the Mean Absolute Percentage (MAPE). Based on the results of precision measurements, it was found that the printer prototype designed to produce high-precision images with affordable pen ink costs and can process digital instructions from a computer using Computer Numerical Control (CNC).

Abstract

The 5G network generation is a modern innovation after it was first introduced by the New Generation Mobile Network (NGMN). The rapid development of mobile devices is marked by the number of companies launching mobile devices with the latest network connection technology, namely the 5G network. In addition, the rapid development of technology has led to an increase in the number of network requirements that are increasingly current. The development of network virtualization and software network functions is proposed as Network Slicing technology. Network Slicing can integrate and distribute independent network resources so that users get services with low latency and high-reliability requirements. The Network Slicing algorithm can reduce energy wastage when used and aims to divide and allocate network resources into several parts in proportion to the expected resource ratio or priority.

Abstract

In a communication system, two main resources are used: transmission power and channel bandwidth. Transmission power is the average power of the transmitted signal. Channel bandwidth is defined as the frequency band allocated for the transmission of the message signal. A goal of general system design is to use these two resources as efficiently as possible. This scientific paper presents the experimental results of the Binary Phase Shift Keying (BSK) communication system on the additive white gaussian noise (AWGN) channel and the Fading channel. To improve system performance, error correction code (ECC) is used for encoding. ECC used include convolutional code (ConvCode) and Hamming code. Experimental results show that for BER=10^(-4) the coding gain of the ConvCode over Hamming code under AWGN is G=0.475dB. Whereas the coding gain of the ConvCode over unencoded BPSK is G=19.6dB.
