A Mobile Ad-hoc NETwork (MANET) is an expert of self-directed functioning, self-configuring, operates without infrastructure and rapidly deployable network. MANET functions without any help of centralized administration. The nodes are independent, self-configuring and rapidly deployable. Nodes are movable because configuration is not fixed and they have limited computing resources. Routing protocols plays a significant role for enhancing Quality-of-Service (QoS) in MANET. The reactive AODV routing protocol faces some difficulties i.e. time delay, long route, mobility and many others during routing.
