Efficient use of channel bandwidth in WiMAX mesh network using concurrent transmission

IEEE 802.16 standard provides a mechanism for maximum use of broadband wireless channel. The primary advantages of WiMAX standard are high data rates, broadband wireless access, high quality of services, and long coverage range with low deployment cost on a metropolitan scale. An efficient method for maximum use of channel capacity is concurrent data transmission. In the WiMAX Mesh mode, allocation of bandwidth can be handled by TDMA scheduling. An important challenge of the concurrent transmission is the interference in the wireless environments. In this paper, we propose a concurrent data transmission algorithm taking into account the interference in the WiMAX mesh mode. The simulation results show that the proposed algorithm yields to increase the performance of WiMAX networks and to minimize grant time durations.
