Various kinds of smart sensors are being developed and released with the growth of sensor technology and Internet of Things (IoT) technology. IoT smart service can provide convenience in our daily lives with these smart sensors. However, the increasing number of mobile sensors and amount of data may increase latency. It may cause network congestion on a particular network. Therefore, we propose a Smart Edge Broker (SEB) to intelligently transmit data traffic generated by a smart city in this paper. SEB can prevent the traffic congestion from being transmitted or bypassed to a location where traffic is not necessary. In addition, SEB can prevent overload in a specific area between services through a location-based transfer. Plus, SEB is suitable to operate it as a fog computing model by placing it at the edge of a smart city network. We conducted a latency measurement experiment and load measurement experiment to evaluate the effectiveness of the proposed Smart Edge Broker. As a result, we found that the latency was reduced by 72%, and the CPU usage was reduced by 63% compared to when the Smart Edge Broker was not used.

Smart Edge Broker，用于在IoT Smart Services中的服务和分布式数据之间进行基于位置的传输

随着传感器技术和物联网（IoT）技术的发展，正在开发和发布各种智能传感器。物联网智能服务可通过这些智能传感器为我们的日常生活提供便利。但是，移动传感器数量的增加和数据量的增加可能会增加等待时间。这可能会导致特定网络上的网络拥塞。因此，本文提出了一种智能边缘代理（Smart Edge Broker，SEB）来智能传输智能城市产生的数据流量。SEB可以防止流量拥塞被传输或绕过不需要流量的位置。此外，SEB可以通过基于位置的传输来防止服务之间特定区域的过载。另外，通过将SEB放置在智能城市网络的边缘，它适合作为雾计算模型运行。我们进行了等待时间测量实验和负载测量实验，以评估所提出的Smart Edge Broker的有效性。结果，与不使用Smart Edge Broker相比，我们发现延迟减少了72％，CPU使用率减少了63％。
