Multiple description coding has been shown to provide flexible and distortion-rate optimal video streaming transmission over lossy links. In this paper, we provide an adaptive MD-FEC algorithm for point-to-multipoint video streaming that approximately minimizes the average distortion of the multicast video. Our new algorithm accomplishes this by adapting both the packet lengths and their number to...
Multiple Description with Forward Error Correction (MD-FEC) coding provides the flexibility, easy adaptivity and distortion-rate optimality that are desirable for delivering streaming video in a network environment with time-varying bandwidth fluctuations and random packet losses. In this paper, we consider the issue of how diverse receivers of a video stream should be grouped — where each group receives...
TCP is the ubiquitous transport protocol in the Internet. However, in a wireless ad-hoc environment where links are unreliable, TCP causes a number of performance issues. The key reason behind this is that TCP considers all packet losses to be due to congestion and reduces its send rate, which is not necessarily appropriate in a lossy ad-hoc environment. In prior work, we have designed Loss Tolerant...
Wireless networks (including wireless mesh networks) provide opportunities for using multiple paths. Multihoming of hosts, possibly using different technologies and providers, also makes it attractive for end-to-end transport connections to exploit multiple paths. In this paper, we propose a multipath transport protocol, based on a carefully crafted set of enhancements to TCP, that effectively utilizes...
