Wireless routers in Wireless Network on Chip confronts more severe congestion problem

so balancing wired/wireless loading has become research focus in WiNoC recently. We propose a priority-based switch arbitration scheme

in which data packets more suitable for transmission through wireless channels are routed to wireless routers; We propose a CARA (congestion-aware routing algorithm) combined with PbSA

which efficiently balance wired/wireless loading and simultaneously avoid deadlock

improving data routing efficiency. Besides

we propose a new virtual channel partition method

which decreases hardware complex for implementing PbSA

and mitigates the adverse effect caused by wireless router congestion. Evaluation shows that the scheme we proposed achieve fine data flow adaptivity with small area and energy overhead

so to improve network performance and routing efficiency under low or high injection rate.
