Auction-Based Resource Allocation for Cooperative Video Transmission Protocols over Wireless Networks

Abstract

Cooperative transmission has been proposed as a novel transmission strategy that takes advantage of broadcast nature of wireless networks, forms virtual MIMO system, and provides diversity gains. In this paper, wireless video transmission protocols are proposed, in which the spectrum resources are first allocated for the source side to broadcast video packets to the relay and destination, and then for the relay side to transmit side information generated from the received packets. The proposed protocols are optimized to minimize the end-to-end expected distortion via choosing bandwidth/power allocation, configuration of side information, subject to bandwidth and power constraints. For multiuser cases, most of current resource allocation approaches cannot be naturally extended and applied to the networks with relay nodes for video transmission. This paper extends the share auction approach into the cooperative video communication scenarios and provides a near-optimal solution for resource allocation. Experimental results have demonstrated that the proposed approach has significant advantage of up to 4 dB gain in single user case and 1.3 dB gain in multiuser case over the reference systems in terms of peak-to-signal-noise ratio. In addition, it reduces the formidable computational complexity of the optimal solution to linear complexity with performance degradation of less than 0.3 dB.

3D video communications: Challenges and opportunities

“…Distributed 3D video coding can be combined with the use of relay nodes enabled with cooperative communications. This idea is presented in [74], where the side information is generated with a 3D wavelet scalable codec and subsequently transmitted directly to the destination. The distributed video coding stream is generated with a transcoding operation at the relay, which transmits the resulting distributed coded video using amplify-and-forward or decode-and-forward cooperative communications.…”

A video distribution game with enhanced quality of experience for wireless networks

“…The application of the game theory in network resource allocation has been investigated in many works, such as [3][4][5][6][7][8][9] and references therein. Some researchers such as Han et al [3], Chang and Subramanian [5] focus on the cooperative aspects of the game theory and coalition formation techniques for resource allocation. Other researchers in [4,[6][7][8][9] are mainly concentrated on applications of the non-cooperative games for resource assignment.…”

“…Other researchers in [4,[6][7][8][9] are mainly concentrated on applications of the non-cooperative games for resource assignment. The application of game theory for video applications has been investigated in some references, such as [3,7]. Han et al [3] try to adopt the cooperative games for designing some efficient transmission protocols for enhanced quality video delivery over wireless networks.…”

“…The presented work in this paper differs from [3] in the fact that we have adopted non-cooperative game theory to model the selfish behaviour of the video sources and the stability properties of the presented algorithms in this work has been proved using NE concept. This work also contrasts from [7] in the fact that in the current work, a stability analysis has been provided to justify the convergence property of the presented distributed resource allocation algorithm.…”
