Abstract: “The design goal of effective routing protocol is challenging task in MANET due to its dynamic challenging characteristics. To design an effective routing protocol which provide correct path between source nodes to destination node is not enough but to improve the quality of service, like bandwidth guarantee battery life and delay. In this paper we are going to improve QoS parameters with the use of cross layer approach. With the use of cross layer we are going to utilize the energy related information from physical and MAC layer of the data link layer which is the responsible of computing the power. And also we are calculating the bandwidth .Both of these parameters is used to detect the stable path from source to destination. We are avoiding the node which has less energy and path which has low bandwidth so as to improve the QoS parameters like network performance, stable route and better delivery of data packets. The routing protocol is built on the top of DSDV. Simulation is done us”
