Fault-tolerant design for data efficient retransmission in WiNoC

There is a sharp decline in the network performance when wireless link fails as data path Wireless Network-on-Chip (WiNoC). To counteract this problem, we propose fault-tolerance mechanism for efficient retransmission of WiNoC. When an error detected transmission process, works to feed back fault information source node real time via signal lines. In node, highest priority assigned backup retransmitted data, and corresponding direct positioned enable packet its destination thereby ensuring efficiency tolerance. Additionally, have improved receiving port router, added redundant buffers mux, dynamically selected non-faulty packets be written local router order avoid disorderly packets. The evaluation results paper demonstrate that compared with methods which are under different conditions, fault-tolerant method drastically improves throughput rate, reduces delay, effectively guarantees reliability network, system performance.
