The ease of deployment and the infrastructure less nature of Mobile Ad hoc Networks (MANETs) make them highly desirable for the present day multi media communications. Traditional routing protocols may not suffice for real time communications which require QoS support from the network. Though there has been considerable research in this area, most of the routing protocols take into account a single QoS constraint. In this paper, we propose an adaptive distributed routing protocol for MANETs which provides a QoS aware path from a given source to destination. The novelty of the protocol lies in taking multiple QoS constraints into consideration. Admission control and bandwidth reservation schemes are incorporated in the protocol to satisfy the QoS constraints of the applications. Relevant information is stored at the intermediate nodes to achieve the required QoS. The protocol has been simulated on top of IEEE 802.11 MAC, in ns-2 network simulator, to show it's correctness and efficiency.
