CSR: Medium: Extensible Distributed Systems Solutions for Community Supported Child-Independent Mobility

儿童独立流动（CIM）是指儿童在没有成人直接监督的情况下在社区内自由活动。人们普遍认为CIM对情感、社会和身体健康至关重要，然而CIM已经急剧下降。该项目利用物联网（IoT）促进社区支持的CIM。在物联网中，每个“东西”都可以感知周围环境，并与附近的其他东西进行无线通信。当所有儿童都有一个小型数字信标，成年社区成员携带移动设备，社区本身也有嵌入式设备时，社区就可以以本地和自组织的方式支持安全的CIM。该项目将利用当地社区资源支持CIM，这些资源通过日益普遍的设备对设备无线链路提供。该项目是根据两个主要研究重点组织的。首先，该项目为连续邻居发现设计了新的协议，使物联网设备能够以最小的能源成本发现附近的其他设备。其次，考虑到能够有效地发现附近的其他设备，该项目探索了家长和其他照顾者为社区数据定义声明性策略的能力。这些策略允许创建评估儿童物联网设备状态的规则，以确保满足所需的安全条件。该项目侧重于儿童独立行动能力的应用领域，这种能力的下降对儿童的健康和福祉产生了负面影响。在这方面，该项目具有重大而广泛的影响。该项目探索了无基础设施物联网应用中隐私和安全的几个新方面。最后，该项目的贡献也广泛适用于许多物联网应用领域，该项目还将探索，例如，智能旅游，在确保参与者享受的同时，跟踪一个有凝聚力的旅游团，这在经济上是重要的。这个项目产生的所有数据和代码工件都将在公共领域的一个可公开访问的存储库上提供，该存储库可在http://github.com/UT-MPC上获得。该代码将在项目结束后至少五年可用和维护。所有结果也将在http://mpc.ece.utexas.edu/上广泛地在线记录。

Child independent mobility (CIM) refers to the freedom of children to move about their neighborhoods without direct adult supervision. It is widely accepted that CIM is essential to emotional, social, and physical well-being, yet CIM has dramatically declined. This project uses the Internet of Things (IoT) to foster community supported CIM. In the IoT, every "thing" can sense its surroundings and communicate wirelessly with other nearby things. When all children have a small digital beacon, adult community members carry mobile devices, and the neighborhood itself has embedded devices, the community can support safe CIM in a local and self-organizing way.The project will support CIM using local community resources, made available using increasingly common device-to-device wireless links. The project is organized along two primary research thrusts. First, the project designs novel protocols for continuous neighbor discovery that enable IoT devices to discover other nearby devices with minimal energy costs. Second, given the ability to efficiently discover other nearby devices, the project explores the ability for parents and other caregivers to define declarative policies for community data. These policies allow the creation of rules for assessing the state of a child's IoT device to ensure that desired safety conditions are satisfied. The project focuses on the application domain of child independent mobility, whose decline is negatively impacting children's health and well-being. In this respect, the project has significant and broad impact. The project explores several novel aspects of privacy and security in infrastructure-less IoT applications. Finally, the project's contributions are also widely applicable to many IoT application domains, and the project will additionally explore, for instance, smart tourism, where keeping track of a cohesive tour group while ensuring the participants' enjoyment can be economically important. All data and code artifacts that result from this project will be made available in the public domain on a publicly accessible repository available at http://github.com/UT-MPC. The code will be available and maintained for at least five years after the end of the project. All results will also be documented extensively online at http://mpc.ece.utexas.edu/.
