Abstract

Real time tracking system technology has been made possible by integrating three technologies, namely global positioning system (GPS), database technologies such as geographic information system (GIS) and mobile telecommunications technologies such as general packet radio service (GPRS). This paper has proposed a vehicle tracking mechanism based on GPS tracker to build a real-time traffic information system. A GPS server is built to process data of position and speed of the vehicle for further processed into vehicle traffic information. The Server and GPS tracker is designed to communicate using GPRS services in real time. Furthermore, the server processes the data from the GPS tracker into traffic information such as traffic jam, dense, medium and smoothly. Test results showed that the GPS server is able to visualize the real position of the vehicle and is able to decide the category of traffic information in real time.

Abstract

Telecommunication technology and applications have developed fast recently. Hence this development will take energy consumption significantly. Many studies have been done on energy efficiency on cellular network. The studies are more focused on energy usage of the base station, as the base station is the component of cellular station which takes the most energy consumption. Therefore this study analyzes energy efficiency on homogeneous network of WCDMA/3G for outdoor environment. Energy consumption of three macro base stations is compared with energy consumption of 12 micro base stations. This comparison analysis has been conducted on the same Area Spectral Efficiency (ASE). The results show that the macro base stations are more efficient for energy usage than the micro base stations. However based on ASE requirements, the micro base stations are more efficient than the macro base stations on both busy hours and non-busy hour.

Abstract

Pertumbuhan yang besar dari penggunaan Information and Communication Technology (ICT) menyebabkan konsumsi energi meningkat drastis. Kenaikan tak terduga konsumsi energi ICT terjadi karena industri seluler telah menyebarkan lebih dari empat juta base station (BS) untuk pengguna/user, masing-masing mengkonsumsi sekitar 25 MWh per tahun. Efisiensi energi pada BS menjadi pertimbangan utama dalam merancang jaringan seluler yang lebih baik. Salah satunya yaitu efisiensi energi jaringan homogeneous WCDMA/3G pada lingkungan indoor dengan mengevaluasi power consumption. Analisis dilakukan dengan mengamati dan membandingkan konsumsi daya atau kebutuhan energi antara dua sistem peletakan BS yaitu sistem dengan 3 macro BS dan sistem 12 micro BS untuk menjangkau pengguna yang berada di dalam ruangan atau lingkungan indoor. Konsumsi daya yang diamati dan dibandingkan adalah konsumsi daya berdasarkan luas area cakupan yang sama dan konsumsi daya berdasarkan kebutuhan area spectral efficiency (ASE) dan juga area power consumption (APC) pada kondisi busy hour maupun non busy hour sehingga ditemukan jarak optimal peletakan BS. Penelitian dilakukan dengan bantuan RUNE Matlab Toolbox. Dari hasil perhitungan diperoleh bahwa konsumsi daya per BS pada micro BS lebih rendah dibandingkan konsumsi daya per BS pada macro BS. Namun, untuk menjangkau luas area yang sama konsumsi daya total untuk penggunaan 3 macro BS lebih efisien dengan persentase sebesar 16,98%, dibandingkan penggunaan 12 micro BS pada kondisi beban atau penggunaan energi maksimal (load=1). Selain itu, dari hasil simulasi diperoleh bahwa, intersite distance mempengaruhi ASE dan APC. Selanjutnya diperoleh penggunaan micro BS lebih efisien dibandingkan macro BS baik pada kondisi busy hour maupun non busy hour pada target  kebutuhan ASE 6 bits/s/Hz/km2 hingga 12 bits/s/Hz/km2.

Abstract

ABSTRACT—Network traffic internet is data communication in a network characterized by a set of statistical flow with the application of a structured pattern. Structured pattern in question is the information from the packet header data. Proper classification to an Internet traffic is very important to do, especially in terms of the design of the network architecture, network management and network security. The analysis of computer network traffic is one way to know the use of the computer network communication protocol, so it can be the basis for determining the priority of Quality of Service (QoS). QoS is the basis for giving priority to analyzing the network traffic data. In this study the classification of the data capture network traffic that though the use of K-Neaerest Neighbor algorithm (K-NN). Tools used to capture network traffic that wireshark application. From the observation of the dataset and the network traffic through the calculation process using K-NN algorithm obtained a result that the value generated by the K-NN classification has a very high level of accuracy. This is evidenced by the results of calculations which reached 99.14%, ie by calculating k = 3.
