Cooperative relaying has the potential to enhance wireless link throughput, while rateless-coded transmission adapts to the wireless channel automatically. The combination of both holds promising performance enhancement for practical wireless communications. Relay selection is a challenging issue in conventional cooperative communications and attracts extensive research. However, there is little literature...
Cooperative communication can obtain spatial diversity without using multiple antennas, and thus achieve more reliable transmission or consume less power. Accordingly, a new cooperative MAC mechanism in wireless networks, the DCMAC, is proposed in this paper. The DCMAC makes full use of the broadcasting characteristics of wireless channel to obtain channel information, chooses the most suitable cooperative...
