Mobile ad hoc network (MANET) is an economic solution for wireless communications, because it doesn't require any prior investment in fixed infrastructure. At the same time, the popularity of group computing has grown rapidly. Multicast is a very useful and efficient means of supporting group-oriented applications, especially in mobile/wireless environments where bandwidth is scarce and equipment has limited power. However, more work is needed to bring these two technologies together. Our research proposal focuses on reliable multicast in mobile ad hoc network, which is crucial to military or disaster rescue wireless multicast applications. To obtain reliable multicast in mobile ad hoc network, a recovery scheme must be employed to ensure end-to-end delivery of unreliable multicast packets for all group members. Moreover, mechanisms coping with node movements are also indispensable. A combined analysis with the hybrid FEC/ARQ scheme and the mobility prediction Aided Dynamic Multicast Routing algorithm will be investigated. More work will be undertaken on the nature of the multicast routing protocols while considering the Minimum Hop Tree (MHT) approach and taking into account the maximum route life. Specification, Validation, Mathematical Analysis, Simulation, and Testbed Experiment are the five stages in any implementation of a protocol.

移动的自组织网络（MANET）是一种经济的无线通信解决方案，因为它不需要任何固定的基础设施的预先投资。与此同时，组计算的普及迅速增长。多播是支持面向组的应用的非常有用和有效的手段，特别是在带宽稀缺且设备具有有限功率的移动的/无线环境中。然而，需要做更多的工作来将这两种技术结合起来。我们的研究计划集中在移动的ad hoc网络中的可靠组播，这是至关重要的军事或灾难救援无线组播应用。为了在移动的ad hoc网络中获得可靠的多播，必须采用一种恢复机制来确保所有组成员的不可靠多播数据包的端到端传输。此外，应对节点移动的机制也是必不可少的。结合FEC/ARQ混合机制和移动性预测辅助的动态多播路由算法进行分析。更多的工作将进行的性质的组播路由协议，同时考虑最小跳树（MHT）的方法，并考虑到最大的路由寿命。规范、验证、数学分析、仿真和测试台实验是协议实现的五个阶段。
