未来的网络物理系统将需要更高的容量，满足更严格的实时要求，并快速适应更广泛的网络动态。然而，使用固定调度来驱动无线网络的操作的传统方法具有固有的限制，使得其不适合于这些系统。作为一种替代方案，我们建议用协调网络运行的特定于域的程序来取代时间表。我们的想法是，网络中的节点将运行自动生成的程序，在运行时做出明智的决定，而不是使用先验的固定时间表。我们将绘制一个特定于域的语言，它使用这种额外的灵活性来显著增加网络容量。此外，构造的程序也足够简单，有效地分析关键的性能指标，如流响应时间和可靠性。最后，我们总结了未来的研究方向。
Future cyber-physical systems will require higher capacity, meet more stringent real-time requirements, and adapt quickly to a broader range of network dynamics. However, the traditional approach of using fixed schedules to drive the operation of wireless networks has inherent limitations that make it unsuitable for these systems. As an alternative, we propose to replace schedules with domain-specific programs that coordinate the operation of the network. Our idea is that nodes in the network will run automatically generated programs that make informed decisions about flows at run time rather than using an a priori fixed schedule. We will sketch a domain-specific language that uses this additional flexibility to increase network capacity significantly. Furthermore, the constructed programs are also sufficiently simple to efficiently analyze key performance metrics such as flow response time and reliability. We conclude with future research directions.
