A Mobile Ad-hoc network (MANETs) is a dynamically formed self-configured network by an autonomous system of mobile nodes connected by wireless links. With the advancements of wireless technology, the necessity of Quality of Service (QoS) is increasing rapidly. Developing QoS constraint routing protocol for MANETs is still a challenging task. As the nodes are free to move randomly, most routing protocols for MANETs are susceptible to node mobility. As routing protocol has to decide which route is able to fulfill the requirement of the desired QoS. Routing is the most important part to accomplish the specified application with desired QoS metrics. This paper is based on design of such a kind of technique that will estimate the available bandwidth throughout the path by assigning precedence. Based on available bandwidth, packets are transferred from source to destination of the applications in queue based on precedence. Results of this approach implemented using network simulator and show that protocol can significantly reduce overheads and decrease overall end-to-end delay and improved packet delivery ratio.
