Optimal relay assignment for cooperative communications

  title={Optimal relay assignment for cooperative communications},
  author={Yi Shi and Sushant Sharma and Yiwei Thomas Hou and Sastry Kompella},
Recently, cooperative communications, in the form of keeping each node with a single antenna and having a node exploit a relay node's antenna, is shown to be a promising approach to achieve spatial diversity. Under this communication paradigm, the choice of relay node plays a significant role in the overall system performance. In this paper, we study the relay node assignment problem in a network environment, where multiple source-destination pairs compete for the same pool of relay nodes in… CONTINUE READING
