Cooperative relaying has come to light in the last decade due to its ability to create spatial diversity in a distributed fashion. However, the intrinsic value of cooperative networks is built upon the fulfillment of node cooperation, which requires not only a theory-approved signaling strategy but a properly designed network protocol to take real benefits from cooperation. More interactions at higher protocol layers, particularly the MAC (Medium Access 摘要 Control) and network layers, are vitally required. In this talk, we present a framework of cross-layer design for cooperative networks regarding the codesign across two critical issues: relay selection and routing. We discuss a MAC-network cross-layer design for next-hop selection, followed by a MAC-physical cross-layer design for relay selection. Based on location information and contention processes, the proposed cross-layer protocol, namely CoopGeo, is detailed. We end up this talk with a brief on our follow-up studies and future research directions. 場次 G2.2 指導教授 吳宗霖教授 博士生姓名 許森貴 學校系所
