Multicast routing algorithm is an important part of the network layer in ad hoc networks. Its main goal is to find an optimal multicast tree that can meet QoS constraints. So the network can not only meet the QoS requirements of data services, but also improve the efficiency of limited network resources. In this paper, we propose a QoS multicast routing protocol, QMRP, which uses an optimization algorithm with multiple QoS objectives to compute the optimal QoS characteristics for the data currently to be delivered. After the source node in the mobile network sends a routing request message, the neighboring nodes selectively forward the message according to their QoS composite index, and the destination node will process the message according to the specific situation after receiving it. Simulation experiments prove that it can significantly improve the transmission rate of mobile network nodes, enhance the stability of the network, and provide strong support for QoS services in Ad Hoc networks.
