Mobile Ad-hoc Network (MANET) is aninfra structureless network that does not require any built-in infra structure and central control. Due to very fast mobility of nodes, there will be drastic changes in the network topology. So an adaptive routing protocol is needed for effective and reliable routing in MANET. Ad-hoc On-demand Distance Vector (AODV) routing protocol is the efficient and prominent routing protocol which may satisfy the above said issue. While making routing process in traditional AODV,onlyone route information will be sent as reply in the reverse path. This reply from the destination may be lost due to fast mobility of modes which in turn leads to the retransmission of route request packets to establish routes.The main cause of this problem is increased communication delay and reduction of several QoS metrics. The main goal of the new Novel QoS aware reliable routing algorithm is to send multiple route replies and establishes reliable data transmission between source and destination. The new NQARR-AODV protocol establishes paths on-request using a reliable reverse pathestablishment method. During pathestablishmentphase, the source node first sends the route requests through all available paths to the destination. The destination node,upon receiving the path requests,inturn rebroadcasts the reverse path requestsas like sender node has done. Upon receiving the multiple route replies from the destination, a path with high reliability is choosen by the source node using the three parameters, the MAC overhead, the Eminence of Link, node residual energy. NQARR-AODV path establishment method works well and requires only minimum steps. It also provides high energy efficiency and load balancing thus prolongs the network life time and makes up high reliability communications. The experimental values prove that the NQARR-AODV algorithmis more reliable and stable and outperforms AODV by reducing energy consumption, overhead and delay. Also NQARR-AODV gains bestratio of packets delivered than that of normal AODV. In our proposed NQARR-AODV protocol, the source node can find QoS aware reliable route to the destination.
