Abstract

Vehicular Ad-Hoc Network (VANET) is a development of the Mobile Ad-Hoc Network (MANET) which makes the vehicle its node. VANET technology is expected to improve driver safety when driving. VANET has network characteristics that change rapidly due to fast node movement. Therefore, VANET requires a routing protocol that is considered suitable and efficient so that sending data packets can take place optimally. This research simulated and analyzed the performance comparison of proactive routing protocol (DSDV), reactive routing protocol (AOMDV) and hybrid routing protocol (ZRP) on VANET in Pekanbaru city. This simulation was carried out using NS-2.35 and SUMO as a mobility generator. Performance is measured using comparison parameters in the form of Packet Delivery Ratio, End to End Delay, and Routing Overhead. The results show that the AOMDV routing protocol is better than Packet Delivery Ratio parameter values with an average value of 99.9%. DSDV routing protocol is better than End to End Delay parameter values with an average value of 0.09 s. While the ZRP Routing Protocol is better than Overhead Routing values with an average value of 0.500. Thus, the protocols have their respective advantages.

Abstract

Bandwidth merupakan salah satu hal yang sangat penting dan harus diperhatikan serta dijaga kestabilan operasionalnya. Untuk menjaga jaringan yang stabil, diperlukan pengalokasian bandwidth. Pengalokasian bandwidth memerlukan informasi terkait kapan saja jam sibuk yang terjadi di PT. Industri Kreatif Digital (PT. IKADA), maka dibutuhkan monitoring pada bandwidth server. Proses pemantauan bandwidth server yang dilakukan PT. IKADA belum optimal menyebabkan jaringan yang tidak stabil dikarenakan pembagian bandwidth yang tidak merata. Pengunduhan aplikasi atau file dalam kapasitas yang besar juga dapat menyebabkan gangguan pada pengguna lain yang sedang melakukan pekerjaannya. Maka diperlukan sistem monitoring bandwidth server untuk dapat memonitor dan mengontrol kapasitas penggunaan bandwidth dari server, apabila penelitian ini tidak selesai, maka PT. IKADA tetap dapat memonitor bandwidth seperti sebelumnya. Berdasarkan permasalahan yang telah diuraikan, diperlukan suatu sistem yang memonitoring kapasitas bandwidth guna mempermudah divisi Network Operation Center untuk mengetahui kapastitas bandwidth yang digunakan apakah sesuai atau tidak, maka dalam penelitian ini, akan dibangun Sistem Monitoring Bandwidth Server. Sistem ini akan dibangun dengan menggunakan PHP sebagai bahasa pemrograman dan MySQL sebagai database manajemen. Berdasarkan pengujian yang telah dilakukan dengan menggunakan metode Blackbox Testing dan Whitebox Testing. Dapat disimpulkan bahwa sistem monitoring ini telah berhasil dibuat dan telah sesuai dengan kebutuhan dari PT. IKADA.

Abstract

Penggunaan dan perkembangan teknologi nirkabel sekarang sudah sangat maju dan luas. Salah satu contohnya adalah VANET (Vehicular Ad-Hoc Network), yang merupakan teknologi nirkabel yang dipasang di dalam kendaraan sehingga kendaraan dapat berkomunikasi satu sama lain (V2V) atau dengan infrastruktur (V2I). Tantangan dalam VANET yang muncul akibat pergerakan dan kecepatan tinggi kendaraan dapat diatasi dengan menggunakan protokol routing. Namun, karena ada banyak jenis protokol routing jaringan nirkabel, diperlukan uji kinerja untuk menentukan protokol routing terbaik yang akan diimplementasikan. Penelitian ini berfokus pada pengujian protokol routing GSR (Geographic Source Routing). Metode penelitian yang digunakan adalah simulasi dan menggunakan perangkat lunak pendukung seperti Openstreetmap, SUMO, dan OMNET++. Evaluasi kinerja protokol routing mencakup parameter Quality of Service (QOS) seperti throughput, end-to-end delay, dan packet ratio. Studi ini melibatkan berbagai skenario yang mencakup perubahan jumlah kendaraan, kecepatan kendaraan, dan keberadaan Road Side Unit (RSU).

Abstract

The increase in the number of vehicles without the development of driving safety technology, tends to create adverse impacts on society, such as a rise in casualties due to road accidents. Therefore, vehicles need information on the condition of the surrounding traffic environment to provide driver with safety. One of the methods used to obtain prompt information between vehicles that move dynamically is communication technology such as Vehicular Ad hoc Network (VANET). VANET has network characteristics that change rapidly due to the highly dynamic node movement. Therefore, it is necessary to choose the right routing protocol for optimal data transmission. In this study, the DSDV (Destination Sequenced Distance Vector), AOMDV (Ad-hoc on Demand Multipath Distance Vector), and ZRP (Zone Routing Protocol) routing protocols were tested using 3 field data scenarios. The first scenario is a variation of the number of nodes 100, 250, 600, and 700 nodes. The second scenario is a variation of the transmission ranges of 250m, 500m, and 1km. The third scenario is the variation of node speeds of 10 km/hour, 20 km/hour, 30 km/hour, 40 km/hour, and 50 km/hour in Pekanbaru city of Riau province. This research was carried out using the simulation method along with the QoS (Quality of Service) performance testing parameters comprising packet delivery ratio, end to end delay, throughput, collision rate, and packet loss. Out of the three scenarios tested, AOMDV is the best routing protocol to be implemented because it outperforms the other two protocol evaluated in all designated scenarios in the paper. Meanwhile, DSDV and ZRP are superior in end to end delay and routing overhead parameters, respectively.

Abstract

The location of the research was carried out at Villa Melati Permai II Housing which is on the Melati Indah Street, Tampan District, Pekanbaru City. Villa Melati Permai II is categorized as middle to upper-class housing but does not have its access network. This research will make the modeling of FTTH (Fiber To The Home) networks with network feasibility parameters to produce quality and appropriate FTTH networks. Manual calculation on the feasibility of FTTH networks using the power link budget and rise time budget shows results within the feasibility limit, which does not exceed the maximum limit for the power link budget of -27 dBm and rise time budget below the total time of bit rates. Calculation with NRZ (Non-Return to Zero) coding produces a downstream value of 0.2813 ns and upstream 0.562 ns. System performance parameters that show signal to noise ratio and bit error rate deliver good quality. Signal to noise ratio exceeds the minimum limit of PT. Telkom standard that is 21.5 dB and the bit error rate does not exceed the optical link standard which is 10-9. Good performance is also shown by eye pattern in optical simulation that displays amplitude signals with the same time and shows clear differences between bits 1 and bits 0.
