“…Path diversity involves the adaptive selection of two or more network paths for the transmission of each video packet using an overlay network infrastructure [14] at the application layer. Although previous work applies path diversity with nonscalable multiple-description coding (for example, see [2] and [7]), we utilize path diversity and scalable video coding [16].…”

“…This overlay infrastructure can also minimize the probability of additional delays and link failures by adaptively routing the video packets. Several examples of such application-layer overlay networks have been proposed in the literature [12], [14].…”

“…Finally, we assume that the application layer of every node in the multihop network relies on an overlay infrastructure [14] that can 1. route video packets via selected links to the destination node and 2. convey information about the expected BER, the queuing delay for each link, and the guaranteed bandwidth under link adaptation from the neighboring nodes in the network topology [5].…”

Abstract-Multihop networks provide a flexible infrastructure that is based on a mixture of existing access points and stations interconnected via wireless links. These networks present some unique challenges for video streaming applications due to the inherent infrastructure unreliability. In this paper, we address the problem of robust video streaming in multihop networks by relying on delayconstrained and distortion-aware scheduling, path diversity, and retransmission of important video packets over multiple links to maximize the received video quality at the destination node. To provide an analytical study of this streaming problem, we focus on an elementary multihop network topology that enables path diversity, which we term "elementary cell." Our analysis is considering several cross-layer parameters at the physical and medium access control (MAC) layers, as well as application-layer parameters such as the expected distortion reduction of each video packet and the packet scheduling via an overlay network infrastructure. In addition, we study the optimal deployment of path diversity in order to cope with link failures. The analysis is validated in each case by simulation results with the elementary cell topology, as well as with a larger multihop network topology. Based on the derived results, we are able to establish the benefits of using path diversity in video streaming over multihop networks, as well as to identify the cases where path diversity does not lead to performance improvements.Index Terms-Wireless systems, multimedia information systems, video, multihop networks, distortion-aware path diversity, cross-layer design.

“…Streaming Transmoders can become quite complex, as multimedia streams have to be retrieved, transmoded and provided at an appropriate pace. It is very important to select good load balancing and buffering schemes, as they greatly influence the resulting multimedia presentation [21].…”

“…The framework introduces a mechanism for transporting large multimedia streams from and to web services, which offers an alternative to DIME. A high-level system architecture is proposed by Roy [21]. It focuses on load balancing and resource distribution without providing details on the standards and mechanisms that are used to build the infrastructure.…”
