Unmanned aerial vehicles (UAVs) have gained interest in different areas due to their versatility and multiple applications. In this case study, a wireless communication system is analyzed between the UAV and its earth station, for the transmission of thermal images in real time and application in fire control. Considering different types of UAVs capable of transporting a high performance thermal camera,...
In this paper we present a scalable multi-view video streaming system with client-side view interpolation. Most parts of the system have been shown to be able to perform in real-time, but never as a complete system. Even though our algorithms are not yet highly optimized, we show that running a complete multi-view streaming system video on consumer hardware is possible today. Since multi-view coding...
Although, it was shown that NC is a promising technique to improve the throughput; especially for multicast environment; it also bears negative side-effects (e.g., high decoding delay). Since streaming video are usually subject to strict delay constraints, high decoding delay must be resolved to enhance the performance of the NC schemes. To overcome this issue, this paper presents a new scheme named...
Modern internet traffic is heavily composed of some form of video communication. In addition, video streaming is slowly replacing regular phone connections. Given that most video transport utilizes Video over Hypertext Transfer Protocol/Transmission Control Protocol (HTTP/TCP), it is important to understand TCP performance in transporting video streams. Recently, multipath transport protocols have...
With the widespread deployment of IEEE 802.11 WLANs and increase in popularity of multimedia communication, video multicast in IEEE 802.11 WLANs has received much attention. One of the most challenging issues in video multicast is to reduce energy consumption of receivers while guaranteeing stable video quality to users. In this paper, we propose a simple but effective video multicast system which...
We investigate the resource allocation problem, including time slot allocation, channel allocation, and power adaptation, in a millimeter Wave (mmWave) network with multiple transmission links, multiple channels, and a PicoNet Coordinator (PNC). Each link has a video session to transmit from the transmitter to the receiver. The objective is to minimize the number of time slots to finish the video...
The lack of adequate support for multicast hinders the ability of WiFi to deliver high quality video in crowded areas with large number of users. In our recent papers, we presented techniques for low-overhead feedback collection and rate adaptation for WiFi multicast. In this demo, we present a platform for evaluating video delivery over multicast using these techniques. The platform does not require...
Wireless video streaming for multi-view plus depth (MVD) frames enables free viewpoint video on wireless devices, where a viewer can freely synthesize any preferred virtual viewpoint from the received MVD frames. To transmit MVD frames over wireless links, existing schemes use digital-based compression to achieve better compression efficiency. However, the digital-based schemes have an issue called...
Research and development on video streaming over vehicular ad hoc networks (VANETs) have expanded rapidly in the last few years. In order to improve road safety and to satisfy road users requirements, video streaming has been proposed to disseminate continuously, an accurate video data, concerning traffic circumstance, travel information, divertissement, etc. High quality video streaming in vehicular...
Broadcasting data to multiple users is widely used in wireless applications. We consider a group of mobile users, within proximity of each other, who are interested in the same video content. Network coded broadcast and cooperative coded communication can improve transmission efficiency and throughput over wireless network separately. In this paper we consider the D2D-assisted wireless network coded...
Video streaming applications over wireless networks have been turned out to be immensely popular in recent times. In this thesis, we study the buffering schemes streaming in heterogeneous wireless networks for the VBR video. An analytical framework is presented to derive the number of expected jitters and buffering delay in average. Through experimenting with a wide range of buffering schemes, we...
This paper presents a novel list decoding approach exploiting the receiver side user datagram protocol (UDP) checksum. The proposed method identifies the possible locations of errors in the packet by analyzing the calculated UDP checksum value at the receiver side. This makes it possible to considerably reduce the number of candidate bitstreams in comparison to conventional list decoding approaches...
Recent broadcast standards support Layered Division Multiplexing (LDM) to achieve graceful degradation as signal quality degrades at the receiver. LDM is accomplished by using different constellations within the same Radio Frequency (RF) spectrum. LDM thus enables delivering multiple service tiers in a single broadcast channel. LDM when used in conjunction with scalable source coding codecs such as...
The most efficient way to solve large scale videostreaming problem is periodic broadcasting for popular videos.Early studies mainly focus on reducing client¡¯s waiting timeand buffer demand. Later, researchers focused on the problemof heterogeneity among clients¡¯ reception bandwidths.Solutions can be categorized in two types: ReceptionBandwidth Adaptable (RBA)...
Supporting end-to-end quality of services for real-time interactive video applications such as videoconferencing and distance learning across the Internet requires a collection of independent networks or domains to work together to route packets between source and destination. Routing packets across the Internet using a feasible path - a path that meets the quality of service (QoS) attributes of video...
Stream Control Transmission Protocol (SCTP) is one of the TCP/IP protocol stack transport protocol. In this paper we aim for improving the video transmission rates by significantly enhancing the SCTP protocol frame structures. We make use of SCTP multi-streaming feature for determining various frame formats that defines the effective transmission. The proposed unidirectional delay technique is used...
A novel interference management approach is proposed for modern communication scenarios, where multiple applications and networks coexist on the same channel resource. The leading principle behind the proposed approach is that the interference level should be adapted to the content being transmitted by the data links to maximize the amount of delivered information. A network setting is considered...
Multimedia streaming applications have high throughput requirement and stringent Quality-of-Service (QoS) guarantee.

Specifically, the Scalable Video Coding (SVC) technology is introduced...

In this work, we propose a time-sensitive incentive-aware mechanism for mobile video offloading by using the idea of crowdsourcing, where video packet holder cooperates with mobile users to deliver video packets to destination. The objective is to maximize video provider and mobile relay users' payoffs. We formulate the interaction among video packet provider and mobile relay users as a two-person...
