The main reason for using wireless communication is to reduce latency as well as power consumption. According to the limitation of resources, the performance of the WNoC is sensitive to the routing algorithm. While an appropriate routing algorithm reduces latency, it should avoid deadlock. In this paper, we propose a novel routing algorithm using Q- learning, which is one of the reinforcement learning methods for balancing wireless network traffic on the chip. Using such an algorithm, the nodes can make decisions based on congestion conditions in the network when transferring flits from the source node to the destination one. The simulation results show that using the proposed reinforcement learning for routing the packets considerably improves the performance of the network; more precisely, the system performance is improved by 8% compared with the previous related works.
