Seamless Integration

Light Fidelity (LiFi) is a new candidate for wireless networking that utilizes the visible light spectrum and exploits the existing lighting infrastructure in the form of light-emitting diodes (LEDs). It provides point-to-point and point-to-multipoint communication on a bidirectional channel at very high data rates. However, the LiFi has small coverage, and its optical gain is closely related to the receiver’s directionality vis-à-vis the transmitter, therefore it can experience frequent service outages. To provide reliable coverage, the LiFi is integrated with other networking technologies such as wireless fidelity (WiFi) thus forming a hybrid system. The hybrid LiFi/WiFi system faces many challenges including but not limited to seamless integration with the WiFi, support for mobility, handover management, resource sharing, and load balancing. The existing literature has addressed one or the other aspect of the issues facing LiFi systems. There are limited free source tools available to holistically address these challenges in a scalable manner. To this end, we have developed an open-source simulation framework based on the network simulator 3 (ns-3), which realizes critical aspects of the LiFi wireless network. Our developed ns-3 LiFi framework provides a fully functional AP equipped with the physical layer and medium access control (MAC), a mobility model for the user device, and integration between LiFi and WiFi with a handover facility. Simulation results are produced to demonstrate the mobility and handover capabilities, and the performance gains from the LiFi-WiFi hybrid system in terms of packet delay, throughput, packet drop ratio (PDR), and fairness between users. The source code of the framework is made available for the use of the research community.

Delivery Network

Pengakses jaringan single server pada saat ini meningkat pesat. Ketika banyak pengguna terhubung pada jaringan single server. Ketika single server atau non CDN (non Content Delivery Network) melayani permintaan dari banyak pengguna. Besar kemungkinan server yang melayani akan terjadi overload dan crash. Melihat dari kebutuhan user dan waktu yang diperlukan menjadi hal yang diutamakan adalah kecepatan akses pengirim paket data video streaming sampai kepada tujuan penerima. Geo DNS  yang diterapkan adalah salah satu solusi yang efektif dan efisien untuk mengatasi masalah tersebut. Arsitektur CDN ini dibangun dengan menggunakan konsep Network Simulator-2 (NS-2) yang memungkinkan proses pentransmisi paket data video streaming didistribusi dengan cepat ke server terdekat yang melayani permintaan client server. pengujian dan percobaan yang dilakukan maka parameter yang diukur adalah delay dan packet loss. Dari hasil pengujian didapat delay 0,279296 s dan packet loss 44,30 % non CDN, sedangkan Delay 0,067609 s dan packet loss 4,12 % Geo DNS diterapkan pada CDN. Maka kesimpulannya adalah jauh lebih baik kinerja Geo DNS pada CDN dibandingkan non CDN.

Our project proposes a robotic vehicle that can be controlled via wireless system of transceiver using radio frequency(RF) and Infrared frequency (IF) .The robotic vehicle may then be operated as desired as commanded through the receiver end of transceiver.This robot is designed with the best optimized architecture consisting of open source hardware ,, colour sensor which is used as a part of camouflaging feature of robot, ESP32 camera module and transceiver module.The transmitter part is connected to the robot and the receiver is with the user by which the person can control the robotic vehicle.Thus in this project our robot will be performing an important application of spying intruders by getting disguised in surrounding and detecting any proximity near it and sending the data to the user. The proposed system consists of a wireless camera for live video streaming surveillance and it will also guard the area from any foreign access using proximity sensor.

The Cost

Communication is a very important area of research in the present era. Expansion of globalization and reduction in the cost of electronic devices has made communication very effective. A large number of researchers from academics and industries are involved in the research on communication and networks. Any novel idea has to be verified on the simulator. A number of simulators are available for network simulations such as Network Simulator (NS2 and NS3), OPNET, NetSim, OMNeT++, REAL, J-Sim and QualNet. NS is an open-source simulation tool that runs on Linux. It is a discreet event simulator for networking research and provides substantial support for simulation of routing, multicast and IP protocols. This chapter provides an overview of NS in a much simpler way. At the completion of this chapter readers will be able to write tcl script to simulate a scenario of network. Every simulation on NS generates a huge trace file; the study of this can be done with the help of AWK script.

Perkembangan teknologi informasi begitu cepat seperti sekarang telah banyak mengubah sudut pandang banyak orang, antara lain sudut pandang orang untuk mengubah dunia pendidikan menjadi lebih baik. Salah satu contohnya pembelajaran berbasis Information and Communication Technologies (ICT) yaitu pembelajaran menggunakan video streaming. Dengan instalasi software open source Wirecast dan Desktop presenter digunakan untuk membuat video pembelajaran Streaming, disiarkan secara real time melalui media broadcast justin.tv (internet TV Channel), diharapkan dapat lebih mendukung konsep pembelajaran kapan dan dimana saja. Masalah terbesar dari teknologi ini adalah keterbatasan bandwidth. Bandwidth adalah parameter penting untuk melakukan streaming dalam jaringan. Sedangkan proses komunikasi menggunakan video digital ini menghabiskan resource yang cukup besar. Sehingga penggunaan wireshark di sini sangat diperlukan untuk menganalisis bandwidth pada paket yang diterima oleh client. Dari hasil pengukuran video dengan standar H.264 resolusi (720 x 540), dengan rata-rata 20 menit dalam pengambilan sampel, sebanyak 30 pengujian sampel streaming video menggunakan wireshark, diperoleh rata-rata throughput keseluruhan 0,343 Mbps, rata-rata throughput terendah 0,309 Mbps dan throughput tertinggi 0,372 Mbps. Dapat disimpulkan bahwa jika dihasilkan throughput yang lebih besar maka kualitas video streaming akan lebih baik, tetapi jika throughput dihasilkan semakin kecil maka kualitas video streaming akan menurun
