The potential offered by the abundance of sensors, actuators, and communications in the Internet of Things (IoT) era is hindered by the limited computational capacity of local nodes. Several key challenges should be addressed to optimally and jointly exploit the network, computing, and storage resources, guaranteeing at the same time feasibility for time-critical and mission-critical tasks. We propose the DRUID-NET framework to take upon these challenges by dynamically distributing resources when the demand is rapidly varying. It includes analytic dynamical modeling of the resources, offered workload, and networking environment, incorporating phenomena typically met in wireless communications and mobile edge computing, together with new estimators of time-varying profiles. Building on this framework, we aim to develop novel resource allocation mechanisms that explicitly include service differentiation and context-awareness, being capable of guaranteeing well-defined Quality of Service (QoS) metrics. DRUID-NET goes beyond the state of the art in the design of control algorithms by incorporating resource allocation mechanisms to the decision strategy itself. To achieve these breakthroughs, we combine tools from Automata and Graph theory, Machine Learning, Modern Control Theory, and Network Theory. DRUID-NET constitutes the first truly holistic, multidisciplinary approach that extends recent, albeit fragmented results from all aforementioned fields, thus bridging the gap between efforts of different communities.
物联网 (IoT) 时代丰富的传感器、执行器和通信所带来的潜力受到本地节点计算能力的限制。为了优化和联合利用网络、计算和存储资源,同时保证对时间关键型和任务关键型任务的可行性,需要解决几个关键挑战。我们提出了 DRUID-NET 框架,通过在需求快速变化时动态分配资源来应对这些挑战。它包括对资源、提供的工作负载和网络环境的分析动态建模,同时考虑到无线通信和移动边缘计算中常见的现象,以及时变配置文件的新估计器。在此框架的基础上,我们旨在开发新的资源分配机制,明确包括服务区分和上下文感知,能够保证明确定义的服务质量 (QoS) 指标。DRUID-NET 通过将资源分配机制纳入决策策略本身,超越了控制算法设计的现有水平。为了实现这些突破,我们将自动机和图论、机器学习、现代控制理论和网络理论的工具结合在一起。DRUID-NET 构成了第一个真正全面的、多学科的方法,它扩展了最近所有上述领域的零散成果,从而弥合了不同社区之间的差距。
