Usage of Wireless networks increasing rapidly due to an increase in the usage of IoT devices. For the better utilization of wireless networks, Ad Hoc networks prepared than Infrastructure based networks. Quality of Service is the primary concern in Ad Hoc networks. QoS in a Multicast routing strategy is needed to adapt to provide better services in Ad Hoc networks. For network group communication On-Demand Multicast Routing Protocol (ODMRP) has a low control overhead. Many schemes have worked on the development of ODMRP, but very few have provided an aware quality mechanism. We propose a new method for reducing the control overhead and also a technique for supporting QoS routing in ODMRP by making an acceptable estimation of available bandwidth. © 2020, World Academy of Research in Science and Engineering.
