有线现场总线长期以来已被证明能有效支持信息物理系统(CPS)。然而,由于易于部署或需要具备支持移动设备能力的新功能,各个领域现在都在努力寻求无线解决方案。针对这一需求,已经提出了低功耗无线协议,但仍无法满足大量CPS应用的要求。因此,我们提出了时间触发无线(TTW),这是一种分布式低功耗无线系统设计,它能将通信能耗降至最低,并提供端到端的定时可预测性、运行时适应性、可靠性和低延迟。评估表明,与最相关的工作动态重配置协议(DRP)相比,通信延迟降低了2倍,无线电开启时间降低了33 - 40%,验证了TTW对令人兴奋的新型无线CPS应用的适用性。
Wired fieldbuses have long been proven effective in supporting Cyber-Physical Systems (CPS). However, various domains are now striving for wireless solutions due to ease of deployment or novel functionality requiring the ability to support mobile devices. Low-power wireless protocols have been proposed in response to this need, but requirements of a large class of CPS applications can still not be satisfied. We thus propose Time-Triggered Wireless (TTW), a distributed low-power wireless system design that minimizes communication energy consumption and offers end-to-end timing predictability, runtime adaptability, reliability, and low latency. Evaluation shows a 2× reduction in communication latency and 33–40% lower radio-on time compared with DRP, the closest related work, validating the suitability of TTW for new exciting wireless CPS applications.
