Network on Chip (NoC) is a prevailing communication platform for multi-core embedded systems. Wireless network on chip (WNoC) employs wired and wireless technologies simultaneously to improve the performance and power-efficiency of traditional NoCs. In this paper, we propose a deterministic and scalable arbitration mechanism for the medium access control in the wireless plane and present its analytical worst-case delay model in a certain use-case scenario that considers both Real-time (RT) and Non Real-time (NRT) flows with different packet sizes. Furthermore, we design an optimization model to jointly consider the worst-case and the average-case performance parameters of the system. The Optimization technique determines how NRT flows are allowed to use the wireless plane in a way that all RT flows meet their deadlines, and the average case delay of the WNoC is minimized. Results show that our proposed approach decreases the average latency of network flows up to 17.9%, and 11.5% in 5 × 5, and 6 × 6 mesh sizes, respectively.

片上网络（NoC）是用于多核嵌入式系统的流行通信平台。片上无线网络（WNoC）同时使用有线和无线技术来提高传统NoC的性能和能效。在本文中，我们为无线平面中的媒体访问控制提出了一种确定性和可扩展的仲裁机制，并在考虑了实时（RT）和非实时的特定使用情况下，提出了其分析性最坏情况时延模型。时间（NRT）流具有不同的数据包大小。此外，我们设计了一个优化模型来共同考虑系统的最坏情况和平均情况性能参数。优化技术确定了如何允许NRT流以所有RT流都满足其期限的方式使用无线平面，WNoC的平均情况延迟最小。结果表明，我们提出的方法在5×5和6×6网格大小下分别将网络流的平均延迟分别降低了17.9％和11.5％。
