Different QOS Based Comparative Simulation Evaluation of Infra-Red and Extended Rate PHY (802.11g) Based on GRP Routing Protocol?

In this paper analysis of Comparative performance of Infra Red WLAN and Extended Rate PHY (802.11g) WLAN is done for 1 and 2 mbps data rate for GRP. We used OPNET Simulation tool we created a network containing 20 mobile nodes with data rate 1 Mbps and 2 Mbps with transmission power 0.005 watts and buffer size 1024000 bits each node moves randomly in the network and simulation time was 1500 sec. Infra Red WLAN and Extended Rate PHY (802.11g) WLAN is compared in terms of 1 Mbps for different QOS’s using GRP protocol. According to the resulted performance we can say that Infra Red performed better in our QOS. The simulation result of the research has practical reference value for further study.
