The Internet of Things connects a large number of smart mobile devices with the Internet, where these devices are embedded with often limited communication, computation, and caching resources. To address the heterogeneity of these devices and achieve efficient overall system resource utilization, researchers have proposed various device-to-device resource sharing models, enabling mobile devices to form device-todevice connections and to share their resources for cooperative task execution. Most of these existing works, however, considered scenarios where mobile devices can share one or two types of resources, and hence inadequately explore the potential of resource sharing among mobile devices. In this article, we introduce a general framework where mobile devices can share any combination of the three types of resources, and it can generalize many existing deviceto- device resource sharing models. In addition, it can achieve more efficient resource allocation by offering mobile devices more flexibility in terms of resource sharing. Based on the proposed framework, we focus on discussing two issues: the optimization issue, regarding how to schedule resources among devices; and the economic issue, regarding how to motivate the device owners to share their resources. We introduce the challenges and potential solutions to these two issues. We further outline several open issues and future directions for the proposed general resource sharing framework.

物联网的通信、计算和缓存资源共享

物联网将大量智能移动设备与互联网连接起来，这些设备嵌入了通常有限的通信、计算和缓存资源。为了解决这些设备的异构性并实现系统整体资源的高效利用，研究人员提出了各种设备到设备的资源共享模型，使移动设备能够形成设备到设备的连接并共享其资源以协同执行任务。然而，这些现有的工作大多考虑了移动设备可以共享一种或两种资源的场景，因此没有充分探索移动设备之间资源共享的潜力。在本文中，我们介绍了一个通用框架，其中移动设备可以共享这三种资源的任意组合，它可以概括许多现有的设备到设备资源共享模型。此外，它可以通过在资源共享方面为移动设备提供更大的灵活性来实现更高效的资源分配。基于提出的框架，我们重点讨论两个问题：优化问题，关于如何在设备之间调度资源；和经济问题，关于如何激励设备所有者分享他们的资源。我们介绍了这两个问题的挑战和潜在的解决方案。我们进一步概述了拟议的一般资源共享框架的几个未决问题和未来方向。我们重点讨论两个问题：优化问题，关于如何在设备之间调度资源；和经济问题，关于如何激励设备所有者分享他们的资源。我们介绍了这两个问题的挑战和潜在的解决方案。我们进一步概述了拟议的一般资源共享框架的几个未决问题和未来方向。我们重点讨论两个问题：优化问题，关于如何在设备之间调度资源；和经济问题，关于如何激励设备所有者分享他们的资源。我们介绍了这两个问题的挑战和潜在的解决方案。我们进一步概述了拟议的一般资源共享框架的几个未决问题和未来方向。
