Multimedia wireless transmission with network coding

Abstract

In recent years, Wireless Local Area Networks (WLAN) have become the premier choice for many homes and enterprises. WiMAX (Worldwide Interoperability forMicrowave Access) has also emerged as the wireless standard that aims to deliver data over long distances, and can potentially provide wireless broadband access as an alternative to the wired cable and DSL networks. Parallel with the surge of wireless networks is the explosive growth of multimedia applications. Therefore, it is important to explore efficient methods for delivering multimedia data in such wireless settings. In this paper, we propose a network coding based scheduling policy to be used at WLAN-like Access Point (AP) or at a WiMAX-like broadcast station that optimizes the multimedia transmission in both broadcast and unicast settings. In particular, the contributions of this paper include (a) a framework for increasing the bandwidth efficiency of broadcast and unicast sessions in a wireless network based on network coding techniques and (b) an optimized scheduling algorithm based on the Markov Decision Process (MDP) to maximize the quality of multimedia applications. Simulations and theoretical results demonstrate the advantages of our approach over the conventional techniques.

“…Nguyen et al [36] present network coding based scheduling policy in order to increase the bandwidth efficiency of multicast and unicast sessions in a wireless network. At the same time, they propose Markov Decision Process based scheduling algorithm to maximize the quality of multimedia applications.…”

Opportunistic Network Coding for Real-Time Transmission over Wireless Networks

“…After network coding algorithms have demonstrated good potential for improving the overall wireless network capacity and throughput, network coding for multimedia transmission over wireless networks was studied in [22]- [28]. It is worth noting here that XOR operations have been widely used to implement network coding.…”

Collaborative video streaming with Raptor network coding

“…It considers the significance of each video packets and intelligently selects network codes for combining packets that can be decoded by several peers. In [5] a network coding system was used for WLAN-like Access Point or WiMAX-like broadcast stations. This method employs an optimized scheduling algorithm based on the Markov Decision Process to maximize the multimedia transmission in both broadcast and unicast settings.…”
