MANET is widely used for Ad hoc-based communications, but it suffers from several deficiencies like mobility cause change in topology and network partitions. The packet losses and congestion is very common scenario in MANET. In this work we provide a novel routing scheme which is able to provide consistent network stability and reliable packet delivery. We develop a routing scheme based on reactive route discovery process related to dynamic source routing protocol by proposing an optimal least busy path effective congestion less scheme which tries to minimize the packet drop keeping in mind the end goal which is to provide high quality path. The quality of our scheme is least busy routes, link stability, path quality, and high response time. The simulation results demonstrate the effectiveness of our proposed method; it is largely unaffected with increase in network mobility and network load. It has been likewise seen that the packet delivery ratio has been increased and the first packet received with the end-to-end delay has been decreased when our proposed method is compared with the conventional DSR protocol.
