Establishing communication through portable devices without the dependence on or constraints of any central infrastructure is possible in Ad-hoc networks. Support for multicast solutions is crucial for mobile ad-hoc systems to become an affordable solution to facilities systems. Multicasting services of proven worth are provided through well established routing protocols in the wired networks. Progressive increase in the mobility of the nodes necessitates these protocols to evolve corresponding methodologies to provide efficient service in the new context. A novel protocol, QoS Enabled Hierarchical Robust Multicast Routing (QHRMR) is proposed in this paper for multicast routing in large IP networks. The priority objectives of QHRMR are to deliver packets to the receivers in an efficient and reliable way with QoS as a primary concern. The detailed protocol for constructing a shared multicast tree is presented in this paper. QoS is the main building block in this protocol to achieve effectiveness, reliable and robust environment.
