Applications requiring real-time communication (RTC) between Internet peers are ever increasing. RTC requires not only congestion control but also minimization of queuing delays to provide interactivity. It is known that the well-established transmission control protocol congestion control is not suitable for RTC due to its retransmissions and in-order delivery mechanisms, which induce significant...
The main contribution of this paper is an end-to-end rate-based congestion control algorithm for unicast quality adaptive video streaming that we call Adaptive Rate Control (ARC). The algorithm is based on end-to-end estimation of both available bandwidth and queue backlog. ARC has been compared with the TCP-Friendly Rate Control (TFRC) algorithm via the ns-2 simulator. In particular, both single...
MPEG-DASH introduced open standards into HTTP streaming, which was a huge step forward. The scope of the MPEG-DASH standard was limited to the Media Presentation Description (MPD) format of the manifest files as well as the segmentation standards for the server, but did not include the client application as part of their standards. Particularly a good representation switching algorithm at DASH client...
NS(Simulator Network) is an object-oriented visual simulator based on large-scale discrete event. It simulates not only the transmission of network data and topology architecture, but also all kinds of IP network circumstance. This paper describes the architecture and characteristics of NS, and also gives the technique and the general process based on NS. The instance of a streaming media applications-based...
In this paper, a differentiated services based congestion control algorithm for Wireless Multimedia Sensor Networks (WMSNs) is proposed. Keeping in mind the characteristics of Wireless Sensor Networks (WSNs) and their possible extensions, the proposed algorithm categorizes WMSNs traffic into six different classes. The algorithm takes a novel and different approach towards congestion control in WMSNs...
