Abstract

While mobile ad-hoc networking (MANET) research has received a considerable attention in recent years, the majority of them have focused on single-tier (e.g., ground) and homogeneous (e.g., same radio for every node) MANET. Few have investigated the potential implications of multitier and heterogeneous natures of MANET on the design and performance of MANET protocols in a systematic manner. For example, one of the stark differences between single-tier and multitier MANET environments is that the multitier MANET naturally creates "coverage asymmetry" due to the much larger coverage area by airborne nodes compared to ground nodes. Consequently, the number of "neighbors" an airborne node sees can be potentially several orders of magnitude larger than that of a ground node. Treating this airborne node same as any ground node will adversely affect the performance of medium access control (MAC) and/or routing MANET protocols. In this paper, we present a detailed multitier MANET architecture, associated issues, and protocols developed. Our novel protocols and simulation tools designed for multitier MANET are described with preliminary performance results.

多层移动自组织网络:体系结构、协议和性能

虽然近年来移动自组织网络(MANET)的研究受到了相当大的关注，但其中大多数研究都集中在单层(例如地面)和同构(例如每个节点的相同无线电)MANET上。很少有人系统地研究MANET的多层和异构特性对MANET协议的设计和性能的潜在影响。例如，单层和多层MANET环境之间的一个明显区别是，多层MANET自然会产生“覆盖不对称”，因为机载节点的覆盖面积比地面节点大得多。因此，机载节点看到的“邻居”数量可能比地面节点大几个数量级。将该机载节点与任何地面节点一样处理将对介质访问控制(MAC)和/或路由MANET协议的性能产生不利影响。在本文中，我们提出了一个详细的多层MANET架构、相关问题和开发的协议。本文描述了我们为多层MANET设计的新协议和仿真工具，并给出了初步的性能结果。
