由于更小、更通用、功能更强大的移动计算设备的进步，自组织网络越来越受欢迎。这些网络的显著特征是所有主机的普遍移动性。这需要重新设计基本的网络服务，包括可靠的多播通信。本文考虑了高度移动的快速移动自组织网络的特殊情况，并认为对于这种网络，传统的组播方法是不合适的。建议将泛洪作为可靠组播的可能替代方案，并用仿真结果来说明其效果。实验结果还显示了一个相当有趣的结果，即当移动性非常高时，即使泛洪也不足以实现可靠的组播。一些替代的，更持久的洪水变化概述。
Ad hoc networks are gaining popularity as a result of advances in smaller, more versatile and powerful mobile computing devices. The distinguishing feature of these networks is the universal mobility of all hosts. This requires re-engineering of basic network services including reliable multicast communication. This paper considers the special case of highly mobile fast-moving ad hoc networks and argues that, for such networks, traditional multicast approaches are not appropriate. Flooding is suggested as a possible alternative for reliable multicast and simulation results are used to illustrate its effects. The experimental results also demonstrate a rather interesting outcome that even flooding is insufficient for reliable multicast in ad hoc networks when mobility is very high. Some alternative, more persistent variations of flooding are sketched out.
