An optimal energy efficient cooperative retransmission MAC scheme in wireless networks
He, Xin; Li, Frank Yong (Chapter; Peer reviewed, 2011)While the benefits of cooperative diversity have been well studied in the literature, cooperative MAC protocol design has also attracted much attention recently. In the single-relay Cooperative Automatic Repeat reQuest ... -
Cooperative Communications inWireless Local Area Networks: MAC Protocol Design and Multi-layer Solutions
He, Xin (Doctoral dissertations at the University of Agder;48, Doctoral thesis; Peer reviewed, 2012)This dissertation addresses cooperative communications and proposes multi-layer solu- tions for wireless local area networks, focusing on cooperative MAC design. The coop- erative MAC design starts from CSMA/CA based ... -

Cooperative MAC design in multi-hop wireless networks: Part I: When source and destination are within the transmission range of each other
He, Xin; Li, Frank Yong (Journal article; Peer reviewed, 2010)Cooperative communication is regarded as a promising technology in future 5G wireless networks to enhance network performance by exploiting time and/or space diversity via distributed terminals. In this paper, we propose ... -
Formal verification of a Cooperative Automatic Repeat reQuest MAC protocol
He, Xin; Kumar, Ram; Mu, Liping; Gjøsæter, Terje; Li, Frank Y. (Journal article; Peer reviewed, 2012)Cooperative communications, in which a relay node helps the source node to deliver its packets to the destination node, are able to obtain significant benefits in terms of transmission reliability, coverage extension and ... -
A Multi-Relay Cooperative Automatic Repeat Request Protocol in Wireless Networks
He, Xin; Li, Frank Yong (Journal article; Peer reviewed, 2010)This paper proposes a Multi-relay Cooperative Automatic Repeat ReQuest protocol (MC-ARQ) for IEEE 802.11 based wireless networks. The proposed distributed relay selection scheme not only selects the best relays but also ... -
Optimization of the relay selection scheme in cooperative retransmission networks
He, Xin; Li, Frank Yong (Chapter; Peer reviewed, 2011)Cooperative MAC protocol design has attracted much attention recently thanks to the development of relaying techniques. In single-relay C-ARQ, the relay selection scheme cannot work efficiently in a dense network, due to ... -
Throughput and energy efficiency comparison of one-hop, two-hop, virtual relay and cooperative retransmission schemes
He, Xin; Li, Frank Yong (Chapter; Peer reviewed, 2010)Two main types of approaches exist for implementing cooperative communications at the MAC layer: virtual-hop relay and cooperative retransmission. While the virtual-hop relay schemes employ relay nodes to forward packets ...
