随机性和过高的通信延迟已经成为大规模工业系统性能提高的重要制约因素。具有低确定延迟的强大通信直接实现准确的网络同步，可以显著提高许多新兴应用的整体系统协调性和运行效率，包括数据中心、工业物联网(IoT)和智能工厂中的网络控制/执行。这些与机器对机器通信相关的应用包含了许多重要的利基市场，具有巨大的规模。为了保护知识产权(IP)不受其相关研究的影响，申请人最近申请了一项专利，题为“端到端同步，自适应链路资源预留和数据隧道”，以实现极其精确的同步，同时减少端到端的通信延迟。该NSERC I2I第一阶段项目将帮助申请者和WORLDiscovery完成相关的技术设计、原型开发和技术演示。本课题技术的主要目标是通过预留必要的通信资源来消除端到端链路上的随机通信时延，进而在动态无线网络中实现最小时延和亚微秒级的端到端同步。将实施本主题技术的关键技术方面，包括端到端同步、通信资源预留和数据隧道。原型网络的性能将通过协调同步、设备分组和端到端同步和延迟最小化的情景感知适配来提高。此外，原型的功能和与现有标准的兼容性将通过基于IEEE 802.11的原型网络进行验证。样机的可靠性将通过严格的实验室测试在具有严酷和动态航道条件的现实环境下进行评估。

Random and excessive communication latency has become a significant constraint for performance improvement in large scale industrial systems. Robust communications with low and deterministic latency, which directly enable accurate network synchronization, could dramatically improve the overall system coordination and operation efficiency of many emerging applications, including data centre, industry Internet of Things (IoT), and networked control/actuation in smart factories. These applications, which are related to machine to machine communications, encompass many important niche markets with enormous sizes.To protect the intellectual property (IP) from his related research, the applicant has recently filed a patent entitled "End-to-end Synchronization, Adaptive Link Resource Reservation and Data Tunnelling" for achieving extremely accurate synchronization while reducing the end-to-end communication latency. This NSERC I2I Phase I project will help the applicant and WORLDiscoveries in finalizing the related technical design, prototype development, and technology demonstration. It will directly accelerate the technology transfer and bolster the commercialization plan for the subject technology.The main objective of the subject technology is to eliminate random communication delay over end-to-end link through reservation of necessary communication resources, and further achieve minimized latency and sub-microsecond level end-to-end synchronization in dynamic wireless networks. Critical technical aspects of the subject technology, including end-to-end synchronization, communication resource reservation, and data tunnelling will be implemented. The performance of the prototype network will be improved with the coordinated synchronization, device grouping and situation-aware adaptation for end-to-end synchronization and latency minimization. Furthermore, the functionalities of the prototype and the compatibility to existing standards will be validated by the IEEE 802.11 based prototype network. The prototype reliability will be evaluated by rigorous lab tests under a realistic environment with severe and dynamic channel conditions.
