RITA: Reliable and Efficient Task Management in Edge Computing for AIoT Systems

人工智能(AIoT)因其在推动基于人工智能的创新以支持智能制造、自动驾驶和智能城市等新兴智能应用方面的巨大潜力，在全球范围内引起了广泛的研究关注。为了处理海量数据和处理计算密集型AI算法，边缘计算已成为增强AIoT能力的关键构建块。AIoT计算任务管理的生命周期由任务卸载决策、任务传输和任务执行组成。为了应对这些挑战，本项目旨在创建一套新的任务管理理论和方法，以实现AIoT系统可靠和高效的边缘计算。为此，我将首先开发一种新颖的并行性和依赖性感知的卸载决策方案，以找到并行度最大、依赖性最小的细粒度任务，从而以更低的能耗卸载更有效的任务工作负载。然后提出了一种新的任务传输协议，该协议采用了一种基于噪声模式的轻量级交叉访问链路预测方案。最后，设计了一种机会任务分配方案，将每个任务分配到多个机会冗余的边缘服务器上，以获得最小的任务执行延迟。将实施全面的AIoT试验台和开放获取软件，以进行绩效评估和演示拟议的任务管理方法。研究成果将有助于欧洲在前景广阔的AIoT领域的竞争力和增长。精心策划的培训活动将使我掌握新的技能和能力，以增强我的创造和创新潜力，并促进我的职业前景。开放的科学实践以及有计划的交流、传播和开发活动将接触到整个社会，并使公民能够看到研究成果。

Artificial Intelligence of Things (AIoT) has been attracting significant research attention worldwide owing to its great potential in boosting the promising AI-based innovations to support emerging smart applications, such as intelligent manufacturing, autonomous driving, and smart city. To handle massive volumes of data and process computation-intensive AI algorithms, edge computing has emerged as a key building block to empower AIoT. The lifecycle of computational task management in AIoT consists of task offloading decision, task transmission, and task execution. To tackle these challenges, this project aims to create a suite of novel theories and approaches of task management towards achieving reliable and efficient edge computing for AIoT systems. To this end, I will firstly develop an original parallelism- and dependency- aware offloading decision scheme to find the fine-grained tasks with maximised parallelism and minimised dependency, such that more effective task workloads can be offloaded with less energy consumption. I will then propose a novel task transfer protocol that adopts a lightweight cross-access link prediction scheme based on the noise patterns. Finally, an opportunistic task allocation scheme will be designed, which allocates each task to multiple opportunistic and redundant edge servers for achieving the minimum delay for task execution. A holistic AIoT testbed and open-access software will be implemented for performance evaluation and demonstration of the proposed task management approaches. The research outcomes will contribute to Europe's competitiveness and growth in the promising AIoT area. Well-planned training activities will equip me with new skills and competences to enhance my creative and innovative potential and promote my career prospects. Open science practices as well as planned communication, dissemination, and exploitation activities will reach out to society at large and make the research results visible to citizens.
