摘要：The IEEE 802.16 technology (WiMAX) facing great challenges due to owning high mobility of mobile nodes, limited radio coverage of wireless devices, time varying nature of wireless medium. The transmission range of base station (BS) has a vital influence and must achieve the most economic case of energy in wireless networks. This paper investigates the effects of transmission range of BSs for two prominent routing protocols- Destination Sequenced Distance Vector (DSDV) and Ad-hoc On-demand Distance Vector (AODV) respectively over WiMAX networks. The NIST WiMAX module is used to configure WiMAX environment and performance differentials are analyzed using NS-2. The QoS metrics used to evaluate the performance are packet delivery ratio (PDR), throughput, routing overhead (RO) and RTR packet loss. Simulation results reveal that performance increases with increasing the transmission range of the BSs. Although both protocols shows almost similar PDR and Throughput results, AODV is more sensitive to the transmission range that is correlated to transmission power of BS than DSDV. Unlike Ad hoc network here DSDV outperforms AODV in terms of RO and RTR routing packet loss probability.
