摘　　要：This paper presents a Hierarchical QoS （Quality of service） multicast routing protocol （HQMRP） for mobile ad-hoc networks. It can provide QoS=sensitive routes in a scalable and flexible way, in the network environment with mobility. In the proposed HQMRP scheme, each local node only needs to maintain local multicast routing information and/or summary information of other clusters （or domains） but does not require any global ad-hoc network states to be maintained. The HQMRP also allows any ad-hoc group member can join/leave the multicast group dynamically, and supports multiple QoS constraints. This paper presents formal description of main procedures for realizing HQMRP, and the proof of correctness and complexity analysis of the protocol. The performance measures of HQMRP are evaluated using simulation. The studies show that HQMRP can provide an available approach to QoS multicast routing for mobile ad-hoc networks.
