Due to the weak diffraction, millimeter-wave (mm-Wave) communication is vulnerable to human blockage. Relay technology is an effective way to cope with LOS link interruption. However, how to quickly find appropriate relay is critical to network performance due to the need of transmission continuity. This paper proposes a fast relay selection (FRS) algorithm based on the geographical location information...
The directivity characteristic in 60GHz communication brings great potential to do spatial reuse in a dense environment, which usually requires the ability of network to support concurrent connections within the same space. This paper proposed a new approach to achieve interference mitigation and spatial reuse, which use the physical reflector as the virtual relay to forward signal to the target node...
In this paper, a cooperative spatial multiplexing scheme is considered for dynamic relay networks. We assume that each relay node is equipped with a single antenna. To obtain spatial multiplexing gains, the distributed multiple-input multiple-output (MIMO) scheme, in which cooperating nodes act as elements of a multi antenna system, has been proposed in many papers. Since the nodes need to know their...
Selective relaying periodically selects one single relay with the best channel quality to participate the communication between source and destination. When OFDM is used as the physical layer technique in the network, a new problem is how to select the best relay since independent subcarriers may have different channel conditions. Several schemes have been presented, while their capacities are still...
