Quality of Service (QoS) is a challenging task to maintain in MANET. Due to frequent route breakup, there will be extra overhead to rediscover the paths. The performance got degraded manifold if networks have malicious nodes with a specific purpose. An attack such as flooding captures limited bandwidth capacity of wireless links makes it typical to maintain QoS for some application. Multimedia applications required real flows that are currently on high demand and thus potentially required in Mobile Ad-hoc networks (MANET). In our earlier work, we had proposed Real Flow Dynamic Queue RFDQ [1], which improves the performance of real flows under variable rate flooding attack. In this article we are exploring RFDQ further with a different perspective, we tried it out with multipath routing protocol under the non-attack environment. Our simulation will compare RFDQ and Priority Queue using multipath routing protocol Ad hoc On-demand Multipath Distance Vector (AOMDV). To verify the performance of RFDQ extensive simulation experiments are performed using different metrics including end to end latency, packet drop , packet delivery fraction, etc. Using various parameters such as queue length, constant bit-rate interval, total experiment time.
