Configurable protocol design and optimization for ubiquitous networks

我们已经目睹了互联网的爆炸性增长，它成为一个无处不在的信息传输基础设施与混合有线和无线链路。然而，当前的网络协议遇到了来自新应用和新兴通信技术的根本挑战。例如，许多媒体丰富的应用，如互联网协议电视有严格的服务质量（QoS）的要求，是非常苛刻的网络资源;未来的车辆网络需要提供紧急消息，这是时间和位置的关键;水下，地下和深空网络依赖于通信信道显着不同于地面的。我们建议开发网络协议，可以灵活地配置，以支持异构应用程序的混合网络与新兴的通信技术。具体而言，我们将开发a）可通过软件配置以支持差异化服务的物理层技术; B）适应不断变化的网络环境和应用的介质访问控制和路由协议;以及c）具有可配置控制参数的传输层协议。本研究的创新点和预期贡献主要体现在三个方面。首先，在不放弃分层网络架构的情况下，所提出的可配置协议可以是可扩展的、鲁棒的和增量式部署的。其次，与所提出的可配置协议的固有的自适应性，我们可以优化协议参数，不仅提高系统性能，而且还使新的服务，是不可能与传统的协议。第三，支持服务差异化的可配置物理层的工作将为传统的信息理论带来新的启发。所提出的协议将在具有软件定义的无线电外围设备的无线测试台中实施和测试。我们的研究的成功将有助于无处不在的网络服务，这将支持许多行业的进步和改革，如商业，制造业，教育，医疗保健，并促进天气预报，自然资源勘探，灾害预警和环境保护。

We have witnessed the explosive growth of the Internet, which becomes a ubiquitous information transport infrastructure with hybrid wired and wireless links. However, the current network protocols encounter fundamental challenges from both new applications and emerging communication technologies. For example, many media-rich applications such as Internet Protocol Television have stringent quality of service (QoS) requirements and are very demanding in network resources; future vehicular networks need to deliver emergency messages which are both time and location critical; underwater, underground, and deep-space networks rely on communication channels significantly different from the terrestrial ones. We propose to develop network protocols that can be flexibly configured to support heterogeneous applications over hybrid networks with emerging communication technologies. Specifically, we will develop a) physical layer technologies configurable by software to support differentiated services; b) medium access control and routing protocols that adapt to changing network environments and applications; and c) transport layer protocols with configurable control parameters. The innovation and expected contributions of the proposed research lie in three aspects. First, without abandoning the layered network architecture, the proposed configurable protocols can be scalable, robust, and incrementally deployed. Second, with the inherent adaptiveness of the proposed configurable protocols, we can optimize protocol parameters to not only improve system performance, but also enable new services that are not possible with the traditional protocols. Third, the work on a configurable physical layer supporting service differentiation will shed new light on traditional information theory. The proposed protocols will be implemented and tested in the wireless testbed with software defined radio peripherals. The success of our research will contribute to ubiquitous network services that will underpin advances and reforms in many industry sectors such as commerce, manufacturing, education, health care, and facilitate weather forecasting, natural resource exploration, disaster warning, and environment safeguarding.
