Systematic Design and Implementation of Network Protocols for Mobile Multihop Wireless Networks

多跳无线网络在当今被广泛部署，其形式可以是无线网状网络、车载自组织网络、具有中继的蜂窝网络或无线传感器网络（WSNs）。在大多数情况下，既充当端主机又充当路由器的节点也会四处移动，从而导致高度动态的拓扑。这些网络现在越来越多地运行TCP/IP协议栈，而TCP/IP协议栈最初并不是为高度动态的网络设计的，从而导致网络性能不佳。此外，出现了新的协议要求，例如需要管理移动性，或无线传感器网络中的定位和时钟同步。 我们正在与不同应用领域的特定多跳无线网络的一系列合作伙伴密切合作，通过设计和评估适当的解决方案，部署分析，模拟和测试平台实验来满足这些网络的协议需求。开发工作良好的新协议不是一项微不足道的任务。在其他方面，它们的设计需要对节点和链路集合的结构以及它们聚合的动态行为有透彻的理解。近年来，网络科学作为一门新兴学科应运而生，为研究网络提供了科学依据。然而，在以系统的方式为高度动态的网络设计协议时，当今的网络科学提供的指导相对较少。 这里概述的研究计划提出了一种新的方法，在多跳无线网络领域的协议设计。我们将应用网络科学的概念，以获得在许多不同的应用领域开发网络协议时的见解。在短期内，这将导致协议更健壮，更适合多跳无线网络的动态特性。从长远来看，将网络科学应用于这些高度动态的多跳无线网络所获得的见解将有助于推进网络科学本身。

Multi-hop wireless networks are widely deployed today, either in the form of wireless mesh networks, vehicular ad-hoc networks, cellular networks with relays, or wireless sensor networks (WSNs). In most cases, nodes, acting both as endhosts as well as routers, also move around, resulting in highly dynamic topologies. Increasingly, these networks are now running the TCP/IP protocol stack, which originally was not designed for highly dynamic networks, resulting in suboptimal network performance. In addition, new protocol requirements have emerged, for example the need to manage mobility, or localization and clock synchronization in wireless sensor networks. We are working closely with a range of partners on specific multi-hop wireless networks in different application domains, contributing to the protocol needs of these networks by designing and evaluating appropriate solutions, deploying analysis, simulations, and testbed experiments. Developing new protocols that work well is not a trivial task. Among other aspects, their design requires a thorough understanding of both the structure of a collection of nodes and links and the dynamic behavior of their aggregation. In recent years, Network Science has emerged as a new discipline to provide the scientific basis for studying networks. Yet to-date Network Science provides relatively little guideance when designing protocols in a systematic way for highly dynamic networks. The research program outlined here proposes a new approach to the design of protocols in the domain of multi-hop wireless networks. We will apply Network Science concepts to gain insights when developing network protocols in a number of different application domains. In the short term, this will result in protocols that are more robust and well-suited to the dynamic nature of multi-hop wireless networks. Longer-term, the insights gained by applying Network Science to these highly dynamic, multi-hop wireless networks will help advance Network Science itself.
