Multicast routing protocols becomes increasingly important in Mobile Ad hoc Networks (MANET) because they effectively coordinate a set of nodes. Meanwhile, multimedia applications become essential need for users of MANET. Such applications are highly demand for Quality of Service (QoS), which makes an efficient QoS multicast routing protocols is very important. In this work we proposed a new position-based QoS multicast routing protocol (PBQMRP). This approach is formed by partitioning the physical area is into equal size hexagonal cells and electing a leader and backup leader nodes for each cell. Efficient routing is performed based on nodes positions to deliver the data to all the receivers. The simulation results show that, comparing with the well-known multicast protocol ODMRP (Demand Multicast Routing Protocol), PBQMRP achieves higher packet delivery ratio with reduced control overhead.
