“…We consider overlay multicast systems based on multiple distribution trees and the push model, such as the ones in [2][3][4][5][6][10][11][12]. Multiple trees offer two advantages: they ensure graceful quality degradation in dynamic overlays, in which peers can leave during the streaming session and they enable nodes to contribute to the overlay with fractions of the stream bandwidth.…”

The two main sources of impairment in overlay multicast systems are packet losses and node churn. Yet, little is known about their effects on the data distribution performance. In this paper we develop an analytical model of a large class of peer-to-peer streaming architectures based on decomposition and non-linear recurrence relations. We analyze the stability properties of these systems using fixed-point analysis. We derive bounds on the probability that nodes in the overlay receive an arbitrary packet of the stream. Based on the model, we explain the effects of the overlay's size, node heterogeneity, loss correlations and node churn on the overlay's performance. Our findings lead us to the definition of an overlay structure with improved stability properties. We show how and under what conditions overlays can benefit from the use of error control solutions, prioritization and taxation schemes. Based on our results, we identify the components that are needed to achieve good data distribution performance in multi-tree-based overlay multicast.

“…To date, the video transmission over wireless networks is still an open problem. [4], [5] and [8] present some wavelet-based encoders that divide the original bit-stream into multiple streams, called multiple description coding (MDC), to tradeoff the error-resilience and coding complexity; [6] and [7] amplify the benefits of using MDC by combining with path diversity, in these approaches each stream is explicitly transmitted over an independent path to the receiver to achieve higher tolerance to packet loss and delay due to network congestion; In [3], the authors propose two flow control algorithms for network with multiple paths between source-destination pair, both are distributed algorithms over the network to maximize aggregate source utility.…”

In this paper, we propose a novel cross-layer framework for jointly controlling and coding for multiple video streams in wireless multihop networks. At first, we develop a cross-layer flow control algorithm which works at the medium access control (MAC) layer to adjust each link's persistence probability and at the transport layer to adjust flow rates. This proposal is designed in distributed manner that is amenable to on-line implementation for wireless networks. And then, a rate-distortion optimized joint source-channel coding (JSCC) approach for error-resilient scalable encoded video is presented, in which the video is encoded into multiple independent streams and each stream is assigned forward error correction (FEC) codes to avoid error propagation. Furthermore, we integrate the JSCC with the specific flow control algorithm, which optimally applies the appropriate channel coding rate given the constraints imposed by the transmission rate obtained from the proposed flow control algorithm and the prevailing channel condition. Simulation results demonstrate the merits and the need for joint QoS control in order to provide an efficient solution for video streaming over wireless multihop networks.
