In this paper, performance of MANET routing protocol was analyzed using OPNET modeler 14.5. The protocols were tested using the same parameters with random mobility. Performance of IEEE 802,11a/b based MANET protocol with respect to scalability has also analyzed with different QoS parameters. Results showed that, with MANET 60 nodes experienced higher throughput compared to MANET 50 nodes. This was due to maintain cluster of nodes in the topology by dividing them into different node sets performance of small size and large network over different IEEE 802.11a and IEEE 802.11b standards and draws a conclusion based on performance of the network over different QoS parameters.
