Currently, 4G mobile communication systems are supported by the 3GPP standard. In view of the significant increase in mobile data traffic, it is necessary to characterize it to improve the performance of current wireless networks. Indeed, video transmission and video streaming are fundamental assets for the upcoming smart cities and urban environments. Due to the high costs of deploying a real LTE...
Nearly three-fourths of the world's mobile data traffic will be video in the next 5 years. Video is one of the most demanding services in terms of network efficiency, reliability, and quality. In this work, we present a comparative performance evaluation of three different video streaming protocols, namely MPEG-DASH, RTSP, and RTMP for both on-demand and live video streaming over 4G and Wi-Fi (under...
Handoff in a distributed IEEE 802.11 Wireless LAN network is a source of significant amount of problems on the video transmission environment. The visual quality of video streaming applications is lowered when stations are in handoff status. In this paper we introduce an architecture of a session proxy (SP), which tries to preserve the quality of the streaming video upon each handoff between access...
Technological advances allow handheld devices to be equipped with faster processors and wireless interfaces, making the performance comparable to laptop Computers. In this paper, we describe real-time video streaming over heterogeneous networks namely Bluetooth, Wi-Fi and GPRS-EDGE. The wireless channel used for communication in different network varies in their Bandwidth, supported Bit rate and Unequal...
The media streaming technology is very appropriate for client applications running on mobile telephones due to its limited memory and bandwidth. A serious problem that has not been fully solved is the control of temporary client disconnections due to the lack of coverage, because it causes the closing of the current session and forces the opening of a new one with the corresponding loss of efficiency...
