Relay Beam Selection With Directional Antennas
Relay Stations (RSs) can be deployed in a wireless network to extend its coverage and improve its capacity. Smart (directional) antennas can enhance the functionalities of RSs by forming one or multiple beams only towards intended receivers. In this paper, the authors focus on the topology control approach for efficient communications in wireless relay networks with smart antennas. This approach pre-computes an antenna pattern for each node such that an efficient network topology can be formed for future communications. The corresponding optimization problem is formally defined as the Beam Selection Problem (BSP).
