Wireless network-on-chip (WiNoC) face serious reliability challenges, and the fault-tolerant design of wireless routers (WRs) has a significant impact on the transmission efficiency of the overall on-chip network. Due to the continuous shrinking of CMOS technology and the integration of wireless technology in complex circuits, WRs appear to become more prevalent. In this paper, we propose a dynamic detection strategy for wireless interface faults in WiNoC, which classifies the fault scenarios of wireless interfaces in WRs, implements wireless interface fault detection in WiNoC operation, and updates the fault scenarios. Meanwhile, a fault-free WR table-based nearest route algorithm is also presented to maximize the network performance. The Evaluations show that the proposed scheme can effectively guarantee the network performance when WR faults occur in the network and is also effective under the case of moderate WR fault rate. •We propose two mechanisms to ensure efficient communication in wireless network.•First, we propose a dynamic detection mechanism for potential faults in the wireless interface.•Next, we propose a WI fault-tolerant routing algorithm to select the optimal routing path.•Finally, the evaluation results show that the proposed scheme maintains low latency and large throughput under moderate faults.
