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.

随机和过度的通信延迟已经成为大规模工业系统中性能改善的重要约束。具有低延迟和确定性延迟的强大通信可以直接实现准确的网络同步，可以显着提高许多新兴应用的整体系统协调和运营效率，包括数据中心，工业物联网（IoT）和智能工厂中的网络控制/驱动。为了保护其相关研究的知识产权，申请人最近提交了一项名为“End-to-end Synchronization，Adaptive Link Resource Reservation and Data Tunnelling”的专利，以实现极其精确的同步，同时减少端到端的通信延迟。NSERC I2 I第一阶段项目将帮助申请人和WORLDiscoveries完成相关的技术设计，原型开发和技术演示。该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延迟，并进一步实现动态无线网络中的最小延迟和亚微秒级的端到端同步。 将实现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、设备分组和用于端到端同步和延迟最小化的情况感知自适应来提高。此外，原型的功能和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。样机的可靠性将在具有恶劣和动态信道条件的现实环境下通过严格的实验室测试进行评估。
