论文摘要
在本章中，已经提出并讨论了针对未来智能城市的软件定义网络（SDN）框架。它还包括一个分布式的地址方案，以动态地促进向智能城市中的设备分配地址。该框架是动态的，可以相应地更新框架的其他组件，而不会干扰框架的其他组件，而无需干扰其他组件，则可以添加和省略模块。在拟议的寻址方案中，新的物联网（IoT）设备将从其现有的相邻对等设备之一接收一个IP地址。这允许城市中的设备充当代理，并从其自己的IP地址生成一组唯一的IP地址，然后可以将其分配给新的（加入）设备；因此，减少了地址开销和延迟的问题，并避免了在地址分配过程中发送广播消息的需求。因此，它为物联网设备实现了可观的带宽和节能。
In this Chapter, a software-defined network (SDN)-based framework for future smart cities has been proposed and discussed. It also comprises a distributed addressing scheme to facilitate the allocation of addresses to devices in the smart city dynamically. The framework is dynamic and modules can be added and omitted by a centralized controlling unit without disturbing the other components of the framework and other modules may be updated accordingly. In the proposed addressing scheme, a new Internet of Things (IoT) device will receive an IP address from one of their existing neighboring peer devices. This allows devices in the city to act as a proxy and generate a set of unique IP addresses from their own IP addresses, which can then be assigned to new (joining) devices; hence, reducing addressing overhead and latency, as well as avoiding the need to send broadcast messages during the address allocation process. Thus, it achieves considerable bandwidth and energy savings for the IoT devices.
