无线网络中的最优广播

Towards Optimal Broadcast in Wireless Networks

Zygmunt J. Haas, Milen Nikolov

摘要:

广播是网络中的一项基本操作,特别是在无线移动自组网(MANET)中.例如,当目的地节点的位置不确定时,或者为了服务发现,所有按需MANET路由协议都使用某种形式的广播。作为网络协议的基本操作,高效广播的重要性早已被网络社区所认识。许多论文提出了越来越有效的广播实施,而其他研究提出了广播性能的界限。在这项工作中,我们提出了一种新的方法来有效的广播网络中的动态拓扑结构,如MANET,我们引入了一个新的广播算法,这样的网络环境。我们评估我们的算法,表明其性能非常接近相应的理论性能界限,即使在存在数据包丢失,例如,MAC层冲突。此外,我们比较了该算法的性能与其他最近提出的计划,包括在各种流动性设置。

英文摘要:

Broadcast is a fundamental operation in networks, especially in wireless Mobile Ad Hoc NETworks (MANET). For example, some form of broadcasting is used by all on-demand MANET routing protocols, when there is uncertainty as to the location of the destination node, or for service discovery. Being such a basic operation of the networking protocols, the importance of efficient broadcasting has long been recognized by the networking community. Numerous papers proposed increasingly more efficient implementation of broadcasting, while other studies presented bounds on broadcast performance. In this work, we present a new approach to efficient broadcast in networks with dynamic topologies, such as MANET, and we introduce a new broadcasting algorithm for such networking environments. We evaluate our algorithm, showing that its performance comes remarkably close to the corresponding theoretical performance bounds, even in the presence of packet loss due to, for example, MAC-layer collisions. Furthermore, we compare the performance of the proposed algorithm with other recently proposed schemes, including in various mobility settings.
