鉴于每年美国大约有80万儿童失踪，因此如何帮助父母追踪孩子成为一个重要问题。即使已经提出了许多儿童跟踪系统，但定位器的高成本和能量限制是限制这些系统应用的绊脚石。为了应对这一挑战，我们设计了一个基于RFID技术的儿童跟踪系统，儿童携带RFID标签，该系统负责通过汇总部署的读者的读数来定位孩子。我们注意到本地处理对高效儿童跟踪的重要性，我们进一步研究了如何将本地可用的计算资源（例如公园员工和访客携带的移动设备）用于服务提供服务。由于移动设备的能源有限，我们通过共同考虑资源分配和用户关联来研究能效优化问题。通过动态更新匹配方法解决了公式的问题。通过广泛的模拟，我们证明了我们提出的解决方案的有效性。
Given the fact that roughly 800 000 children are reported missing in the United States every year, how to assist parents to track their children becomes an important problem. Even though many children tracking systems have been proposed, the high cost and energy limitation of locators are the stumbling blocks which limit the application of those systems. To address this challenge, we design a children tracking system based on RFID technology, where children carry RFID tags and the system is responsible for locating the children by aggregating the readings from the deployed readers. Noting the importance of localized processing for efficient children tracking, we further study how the locally available computing resource, such as the mobile devices carried by the park employees and visitors, can be utilized for service provisioning. Since mobile devices have limited energy, we study an energy efficiency optimization problem by jointly considering the resource allocation and user association. The formulated problem is solved by a dynamic updating matching approach. Through extensive simulations, we have demonstrated the effectiveness of our proposed solution.
