In recent years network design has grown to accommodate emerging areas of application such as smart cities. The "smart city" concept combines the information and communications technology; where heterogeneous end devices with different capabilities and resource requirements coexist. Thousands of these devices form a wireless mesh network (WMN), wireless sensor network (WSN), or an Internet of Things (IoT) to enable efficient information collection from the heterogeneous devices. The gathered information is then analyzed to realize appropriate and timely decisions for various city operations and services [46]. The "smart city" applications include smart traffic lights, streetlights, surveillance, emergency services, and environmental monitoring. The networks in smart cities must react to communication link and node failures in a matter of milliseconds and ideally be able to predict future states and anticipate the demands of applications, services, and network environments. For instance, city-scale video surveillance applications demand high bandwidth to guarantee timely delivery of critical events to interested observation centers. To enable these networks to reach their intended potential, new models must be developed that can enable the reliable, efficient, and adaptive behavior of the networks; these are properties that cannot be supported by the current generation of wireless network designs that are based on legacy networking stack architecture. The proposed research will fill the gap between existing designs of wireless networks and demands of emerging wireless network applications such as in smart cities. Software-defined networking (SDN) is on track to become the standard network architecture; thus, my design of next-generation wireless networks will be structured to fit SDN paradigm. The SDN architecture is composed of management, control, and infrastructure (data) planes, where network policy is defined at the management plane. The control layer then translates policies into network configuration rules for infrastructure layer devices, according to a global network view. SDN further supports network programmability and implementations that are portable and extensible. The proposed research will design new algorithms, protocols, and architectures to enable reliable network operations. The control plane design will propose a new concept of the possible separation to a fast and a slow changing network state behavior to support efficiency and agility. The adaptive network operation will be based on a novel idea of combining network data flow context and analytics, which honors constraints from different SDN planes. I will produce a programmable, reliable, efficient, agile, and self-adaptive wireless network design targeted for, but not limited to, "smart city" applications, such as smart streetlights, traffic lights, and surveillance.

近年来，网络设计已增长，以适应智能城市等新兴领域。 “智能城市”概念结合了信息和通信技术；具有不同功能和资源需求的异质端设备共存。这些设备中有数千种形成无线网络网络（WMN），无线传感器网络（WSN）或物联网（IoT），以从异质设备启用有效的信息收集。然后分析收集的信息，以实现各种城市运营和服务的适当和及时的决定[46]。 “智能城市”的应用包括智能交通灯，路灯，监视，紧急服务和环境监测。 智能城市中的网络必须在毫秒内对通信链接和节点失败做出反应，理想情况下可以预测未来的状态并预测应用程序，服务和网络环境的需求。例如，城市规模的视频监视应用程序需要高带宽，以确保将关键事件及时交付给感兴趣的观察中心。为了使这些网络能够发挥其预期的潜力，必须开发新的模型，以实现网络的可靠，高效和自适应行为；这些是基于旧网络堆栈体系结构的当前一代无线网络设计无法支持的属性。拟议的研究将填补无线网络现有设计与新兴无线网络应用程序（例如智能城市）的需求之间的空白。 软件定义的网络（SDN）可以成为标准网络体系结构；因此，我的下一代无线网络的设计将结构为适合SDN范式。 SDN体系结构由管理，控制和基础架构（数据）平面组成，在管理平面上定义了网络策略。然后，根据全局网络视图，控制层将策略转化为基础结构层设备的网络配置规则。 SDN进一步支持可移植和可扩展的网络可编程性和实现。拟议的研究将设计新的算法，协议和体系结构，以实现可靠的网络操作。控制平面设计将提出一个新的概念，即可能将可能分离到快速且缓慢变化的网络状态行为，以支持效率和敏捷性。自适应网络操作将基于结合网络数据流上下文和分析的新颖概念，该想法旨在表彰来自不同SDN平面的约束。我将制作一个可编程，可靠，高效，敏捷和自适应的无线网络设计，它针对但不限于“智能城市”应用，例如智能路灯，交通灯和监视。
