The mobile adhoc network (Manet) has been identified as keen networking scenario in modern internet world. The most networking solutions have been enabled to access through mobile devices. The physical characteristics of mobile nodes keep changing the topology of network at each second. However, achieving higher streaming performance is most important in point of quality of service. There exist numerous techniques to route data packets between the source and sink/destination nodes, but suffer with poor performance. To overcome the deficiency, a dynamic multi constraint routing algorithm has been presented in this paper. The method considers different parameters like energy, lifetime, traffic, mobility speed, direction and hop count in route selection. According to the above mentioned parameters, the multi constraint algorithm estimates streaming support score (SSS) for any route to perform routing of packets. The algorithm improved routing performance of routing and increases the streaming rate in Manet.
