Optimal resource allocation is critical to the efficiency of cooperative communications. In this paper, we develop an auction-based
power allocation mechanism for network-coded cooperation in wireless networks, in which the sources compete for the relay
power for maximum utility, while the relay node assigns the resource in accordance with the bids from the sources. Moreover,
to improve the resource utilization, the relay node is allowed to perform network coding across the received information for
the same destination. Finally, numerical results validate the performance of the proposed algorithm, and show that there exists
a tradeoff between the system outage probability and the power consumed at the relay node. 相似文献

1IntroductionWith the developing of packet switching and trans-mission technologies,many IP-oriented applicationshave experienced a substantial growth,makingit pos-sible for various real-ti me broadband video servicesviathe Internet.However,current access networktechnologies can only offer512k-2M subscriberbandwidth,whichis unable to meet the broadband de-mand of emerging3Tnet services such as high-defini-tion video(HDTV)and real-ti me network TV broad-cast.Therefore,the access network sti… 相似文献
