近年来，随着嵌入式设备变得更小，更便宜和更多样化，对向用户呈现有价值信息的城市传感系统的需求正在增加。然而，在实现城市传感系统时，从传感器到数据中心的通信信道提出了一个问题，特别是关于为每个传感器节点提供IP/移动的网络的成本。许多现有的研究试图解决这个问题，但他们通常限制使用的传感器类型或传感器之间的距离。在本文中，我们提出了一种新的传感器数据收集系统模型，其中移动的中继节点传输的传感器数据到数据中心。我们在模仿真实的世界的条件下进行了模拟，以验证所提出的系统的实用性。该模拟使用从交通调查中积累的数据来密切模仿真实的世界中的行人。我们评估了所提出的系统有足够的能力，在城市传感系统，不是实时约束下使用。
In recent years, as embedded devices become smaller, cheaper and more diverse, the demand for urban sensing systems that present valuable information to users is increasing. However, in achieving urban sensing systems, the communication channel from the sensors to the data centers pose a problem, especially in respect to the cost of furnishing IP/mobile networks for each and every one of the sensor nodes. Many existing researches attempt to tackle this problem, but they generally limit either the types of sensors used or the distances among the sensors. In this paper, we propose a new sensor data collection system model in which mobile relay nodes transport the sensor data to the data center. We ran simulations under conditions imitating the real world to verify the practicality of the proposed system. This simulation uses data accumulated from traffic surveys to closely imitate pedestrians in the real world. We evaluated that the proposed system has sufficient ability to use in urban sensing systems that are not under the real-time constraint.
