Wireless network-on-chip (WiNoC) has been introduced as an efficient communication paradigm that can provide high bandwidth and low latency wireless links among long-distance cores. However, the increase of demand for using these shared wireless links and the presence of few numbers of these channels on a chip leads to port contention in WiNoCs. This problem increases the average packet latency as well as the network latency. Therefore, a fair arbitration mechanism is required to eliminate port contention in wireless routers (WRs) and improve the utility of the output port. In this study, we propose a new arbitration mechanism for crossbar switch that can fairly allocate the port priorities based on the current traffic load and the wireless channel bandwidth. The simulation results under synthetic traffic patterns show that the proposed arbitration scheme reduces the average latency and improves the network throughput compared to round robin-based WiNoC.

片上无线网络（WiNoC）已被引入为一种有效的通信范例，可以在长距离内核之间提供高带宽和低延迟的无线链路。但是，对使用这些共享无线链路的需求的增加以及芯片上这些信道数量的减少导致WiNoC中的端口争用。此问题增加了平均数据包延迟以及网络延迟。因此，需要一种公平的仲裁机制来消除无线路由器（WR）中的端口争用并提高输出端口的实用性。在这项研究中，我们为纵横制交换机提出了一种新的仲裁机制，该机制可以根据当前流量负载和无线信道带宽公平分配端口优先级。
