The wireless network on chip WiNoC introduces wireless links in the traditional network on chip (NoC), which reduces the network diameter and enables high-throughput, low-latency data communications. In addition, if wireless nodes can dynamically request data transmission, wireless bandwidth will be more effectively utilized. In order to implement a conflict-free, adaptive bandwidth allocation strategy, a priority-based dynamic media access control mechanism has been designed. In this work, a dynamic priority calculation method has been proposed based on the packets’ transmission time and the waiting time in the queue. Then, a priority calculating unit is designed to calculate the dynamic priority of the packet. Finally, the central control unit designed obtains the dynamic priority of the packets, and dynamically authorizes the use rights of the wireless medium according to the priority of the data packet. Simulation experiments show that the media access control mechanism proposed in this paper has significant improvements in throughput, delay, and power consumption performances compared with other mechanisms [S.Deb et al., Wireless NoC as interconnection backbone for multicore chips: promises and challenges, IEEE J.

The intestinal microbial flora has risen to be one of the important etiological factors in the development of diseases like colorectal cancer, obesity, diabetes, inflammatory bowel disease, anxiety and Parkinson's. The emergence of the association between bacterial flora and lungs led to the discovery of the gut–lung axis. Dysbiosis of several species of colonic bacteria such as Firmicutes and Bacteroidetes and transfer of these bacteria from gut to lungs via lymphatic and systemic circulation are associated with several respiratory diseases such as lung cancer, asthma, tuberculosis, cystic fibrosis, etc. Current therapies for dysbiosis include use of probiotics, prebiotics and synbiotics to restore the balance between various species of beneficial bacteria. Various approaches like nanotechnology and microencapsulation have been explored to increase the permeability and viability of probiotics in the body. The need of the day is comprehensive study of mechanisms behind dysbiosis, translocation of microbiota from gut to lung through various channels and new technology for evaluating treatment to correct this dysbiosis which in turn can be used to manage various respiratory diseases. Microfluidics and organ on chip model are emerging technologies that can satisfy these needs. This review gives an overview of colonic commensals in lung pathology and novel systems that help in alleviating symptoms of lung diseases. We have also hypothesized new models to help in understanding bacterial pathways involved in the gut–lung axis as well as act as a futuristic approach in finding treatment of respiratory diseases caused by dysbiosis.
