Abstract :
The main function of relay station is to enhance the network capacity and extend the coverage area. This paper analyses the performance of relay stations in IEEE 802.16j Mobile Multi-hop Relay (MMR) WiMAX for the transparent and non-transparent modes. The performance of these relays is evaluated based on the throughput for the downlink and uplink transmission using National Chiao Tung University - network simulator (NCTU-ns) module. This study shows that the sustained rate for uplink transmission is 0.471 Mbps while for the downlink in the relay mode is about ten times higher either for transparent or non-transparent relay types.
