In wireless networks-on-chip

wireless communication congestion and fault have a severe impact on the communication efficiency of the entire network-on-chip. Therefore

this paper proposes a fault-tolerant routing algorithm for wireless communication congestion and faults. Firstly

a wireless communication congestion and fault aware model is designed. The model can get the congestion and fault information of the wireless node communication pair

encode it and send it to the routers in subnet. Then the router in the subnet determines whether the data packet uses wireless transmission according to the received wireless node communication pair status information. Experiments show that the proposed scheme can guarantee lower network delay and higher network throughput under smaller additional area overhead and power consumption than the comparison schemes

and exhibit good performance to tolerant permanent faults of wireless node communication pairs.
