项目摘要

Multihop wireless networks (MWNs) have established themselves in a range of domains: vehicular ad-hoc networks, mobile ad-hoc networks, wireless mesh networks, wireless sensor networks, home networking, or even as extensions in cellular networks. The co-operative nature of the nodes and the absence of a fixed infrastructure make them very attractive where fast deployment, low cost, or support for strong mobility is required. Networking protocols for such networks have been designed with the assumption that nodes need to co-operate to achieve network-wide goals, with all nodes involved in operating and managing the network.At the same time, wired networks are seeing a paradigm shift towards Software-Defined Networking (SDN). SDN proposes a network architecture with a (logically) central controller that collects information about the whole network. This central entity makes network-wide decisions about routes and resource usage. The network routers and switches become much simpler and consequently cheaper. They are instructed by the SDN controller how to forward packets, removing the requirement for them to be involved in any network-wide decisions. The goal is to facilitate the introduction of new and innovative services, to simplify network management, to allow for better/more optimized use of resources, and to reduce the costs of offering communication services.This SDN paradigm is fundamentally different from the distributed network protocols prelevant in today's MWNs. However, SDN is quite promising for such networks as well. WMNs, for example, are severely resource-limited (bandwidth, energy, etc.). The central controller, having global knowledge of the network, can optimize resource usage network-wide. Yet efficiently supporting this paradigm over high-latency, lossy, and bandwidth-constrained wireless links is not trivial. In our research, we are exploring how to best deploy the SDN architecture in multihop wireless networks. The key idea is to apply various clustering approaches to reduce overhead, improve responsiveness, and provide robustness. We will demonstrate the advantages of our proposed designs in a number of ways. We will apply and evaluate popular SDN techniques such as traffic engineering or network slicing. We will also design and implement new global optimizations that address the unique challenges of MWNs.The research outcomes will simplify the deployment and increase the flexibility of future MWNs. It will enable us to apply many of the advances made in wired SDNs to MWNs. As a result, it will become easier for ISPs to offer rural mesh networks that provide Internet access in remote communities or for vendors to offer new services in home networks. Furthermore, managing MWNs via SDN will make it easier for telcos to integrate them as access networks with next-generation core networks that are similarly based on SDN.
多跳无线网络(MWNs)已经在一系列领域建立了自己的地位:车辆自组织网络、移动自组织网络、无线网状网络、无线传感器网络、家庭网络,甚至作为蜂窝网络的扩展。在需要快速部署、低成本或支持强移动性的地方,节点的协作性质和固定基础设施的缺乏使它们非常有吸引力。这种网络的网络协议是基于这样的假设来设计的,即节点需要合作以实现全网范围的目标,所有节点都参与网络的操作和管理。与此同时,有线网络正在向软件定义网络(SDN)转变。SDN提出了一种网络架构,其中(逻辑上)中央控制器收集整个网络的信息。这个中心实体做出关于路由和资源使用的全网决策。网络路由器和交换机变得更简单,因此更便宜。它们由SDN控制器指示如何转发数据包,从而消除了它们参与任何网络范围决策的要求。其目标是促进引进新的和创新的服务,简化网络管理,允许更好/更优化地利用资源,并降低提供通信服务的成本。这种SDN范例与当今MWNs中流行的分布式网络协议有着根本的不同。然而,SDN对于这样的网络也是很有前途的。例如,wmn资源严重受限(带宽、能源等)。中央控制器具有网络的全局知识,可以在网络范围内优化资源使用。然而,在高延迟、有损和带宽受限的无线链路上有效地支持这种范式并非易事。在我们的研究中,我们正在探索如何在多跳无线网络中最好地部署SDN架构。关键思想是应用各种集群方法来减少开销、提高响应性和提供健壮性。我们将以多种方式展示我们提出的设计的优点。我们将应用和评估流行的SDN技术,如流量工程或网络切片。我们还将设计和实施新的全局优化,以解决MWNs的独特挑战。该研究成果将简化未来MWNs的部署并增加其灵活性。它将使我们能够将有线sdn的许多进步应用于MWNs。因此,互联网服务提供商将更容易提供在偏远社区提供互联网接入的农村网状网络,或者供应商将更容易在家庭网络中提供新服务。此外,通过SDN管理MWNs将使电信公司更容易将其作为接入网络与类似基于SDN的下一代核心网络集成。
