Reliable multicast and related issues in mobile ad hoc networks

点击翻译按钮获取中文摘要

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.
