There are increasing demands for real-time streaming video applications over the Internet. However, the current generation Internet was not originally designed for real-time streaming applications and only provides best-effort services, so there are many challenges in the deployment of video streaming applications over the Internet. This thesis investigates a hybrid end-to-end rate adaptation framework that provides application-level enhancements to achieve Quality of Service (QoS) for MPEG-4 FGS-Encoded video bandwidth on the path and the terminal process capabilities based on the packet-loss ratio and then determine their subscribing rate of video streams. The sender adjusts the transmission rate based on the packet-loss ratio and then determine their subscribing rate of video streams. The sender adjusts the transmission rate based on the proportion of load status feedbacks from the receivers. The sender and the receivers act together to minimize the possibility of network congestion by adjusting the transmission rate to match the network conditions. This framework achieves inter-receiver fairness in a heterogeneous multicast environment and improves QoS stability for MPEG-4 FGS video streaming over the Internet.

Real Time Traffic

3G long term evolution (LTE) introduces stringent needs in order to provide different kinds of traffic with Quality of Service (QoS) characteristics. The major problem with this nature of LTE is that it does not have any paradigm scheduling algorithm that will ideally control the assignment of resources which in turn will improve the user satisfaction. This has become an open subject and different scheduling algorithms have been proposed which are quite challenging and complex. To address this issue, in this paper, we investigate how our proposed algorithm improves the user satisfaction for heterogeneous traffic, that is, best-effort traffic such as file transfer protocol (FTP) and real-time traffic such as voice over internet protocol (VoIP). Our proposed algorithm is formulated using the cross-layer technique. The goal of our proposed algorithm is to maximize the expected total user satisfaction (total-utility) under different constraints. We compared our proposed algorithm with proportional fair (PF), exponential proportional fair (EXP-PF), and U-delay. Using simulations, our proposed algorithm improved the performance of real-time traffic based on throughput, VoIP delay, and VoIP packet loss ratio metrics while PF improved the performance of best-effort traffic based on FTP traffic received, FTP packet loss ratio, and FTP throughput metrics.

TV over IP merupakan salah satu aplikasi komunikasi multimedia yang memanfaatkan prosesstreaming dalam pengiriman paket-paket data videonya melalui jaringan Internet Protokol (IP). Karenaditerapkan pada jaringan yang berbasis IP, maka akan menggunakan transmisi secara real time yang dapatdibroadcast melalui wireless LAN. Smartphone android akan memberikan manfaat yang lebih karena sudahdilengkapi dengan perangkat wireless. Dalam makalah ini dibahas perancangan server TV over IP denganmenggunakan USB TV tuner untuk menangkap siaran televisi. Untuk membroadcast siaran televisi digunakanperangkat access point melalui jaringan wireless LAN. Pengguna smartphone android yang mempunyaiperangkat wirelss dapat mengakses siaran televisi yang dibroadcast oleh server. Dari implementasi yang telahdilakukan akan dianalisa kualitas layanan streaming atau Quality of Services (QoS) berupa throughput, delay,jitter, dan packet loss. Analisis perencanaan penambahan user dengan simulasi penambahan background trafficdan perencanaan jarak yang semakin jauh dari server akan menurunkan kualitas layanan. Nilai througput akanberbanding terbalik dengan packet loss, tetapi pada pengujian yang dilakukan nilai jitter tidak stabil karenaberpengaruh dari interval delay yang tidak teratur pada paket yang diterima. Jadi dapat disimpulkan bahwasemakin banyak user yang mengakses streaming server maka nilai kualitas layanan akan semakin menurunkarena bandwidth akan semakin kecil yang disebabkan oleh padatnya traffic pada wireless LAN. Denganperancangan TV over IP ini dapat mempermudah bagi pengguna perangkat yang mempunyai wireless sepertismartphone android untuk meengakses siaran televisi lokal di dalam area jangkauan wireless. Dengan layananTV yang berbasis IP akan menghasilkan gambar yang lebih interaktif. Karena merupakan layanan streamingmaka TV over IP rentan dengan kebutuhan bandwidth dengan jumlah kenaikan user dan juga padaperancangan wireless terbatas pada jarak tertentu.

A Tonido cloud server provides a private cloud storage solution and synchronizes customers and employees with the required cloud services over the enterprise. Generally, access to any cloud services by users is via the Internet connection, which can face some problems, and then users may encounter in accessing these services due to a weak Internet connection or heavy load sometimes especially with live video streaming applications overcloud. In this work, flexible and inexpensive proposed accessing methods are submitted and implemented concerning real-time applications that enable users to access cloud services locally and regionally. Practically, to simulate our network connection, we proposed to use the Raspberry-pi3 model B+ as a router wireless LAN (WLAN) that enables users to have the cloud services using different access approaches such as wireless and wireline connections. As a case study for a real-time application over the cloud server, it is suggested to do a live video streaming using an IP webcam and IVIDEON cloud where the streaming video can be accessed via the cloud server at any time with different users taking into account the proposed practical connections. Practical experiments showed and proved that accessing real-time applications of cloud services via wireline and wireless connections is improved by using Tonido cloud server's facilities.

<p>The video streaming is one of the important application which consumes more bandwidth compared to non-real-time traffic. Most of the existing video transmissions are either using UDP or RTP over UDP. Since these protocols are not designed with congestion control, they affect the performance of peer video transmissions and the non-real-time applications. Like TFRC, Real-Time Media Congestion Avoidance (RMCAT) is one of the recently proposed frameworks to provide congestion control for real-time applications. Since the need for video transmission is increasing over the wireless LAN, in this paper the performance of the protocol was studied over WLAN with different network conditions. From the detailed study, we observed that RMCAT considers the packet losses due to the distance and channel conditions as congestion loss, and hence it reduced the sending rate thereby it affected the video transmission.</p>
