Path Selection in WiMAX Networks With Mobile Relay Stations
Introduction of mobile relays into networks based on IEEE 802.16 standard brings new challenges. The paper proposes signaling mechanism for acquisition of channel state information for mobile relays and provides detail analysis of the amount of signaling overhead caused by their introduction. In addition, the investigation whether the connection of the mobile users through the mobile relays enhances the system performance is carried out. The obtained simulation results indicate that by means of mobile relays, the overall throughput can be increased and signaling overhead reduced.
