Mobile Ad-hoc Network (MANET) is a structure less mobile network, where the nodes interconnect with each other in spite of recurrent changes in network topology outstanding to mobility, intrusion and extremely error inclined to environment. Multimedia statement within mobile ad hoc network contains certain Quality of Services (QoS) constraints. Providing QoS in painter isn't a straightforward task thanks to its broadcast and dynamic nature, node quality and resource constraints. There exist several protocols that pay attention of the QoS. Ad-hoc On-Demand Distance Vector (AODV) routing protocol is one amongst the documented MANET protocol, however have some limitations in term of QoS constraints. Many modifications are urged towards improvement in AODV performance to fulfil QoS challenges through that specialize in bandwidth, Packet delivery size relation, energy and mechanism overheads. This paper solely summarizes all such modifications urged for AODV, Along with their benefits and limitations. The aim of this paper is to facilitate literature survey in future researches such that numerous proposed alterations in AODV routing protocol with quality of service parameters like bandwidth, delay, jitter and packet delivery can be probed quickly,and to classify areas for future research.
