Abstract

Abstract: To prevent communication failure in presence of severe underground coal-mine accidents, a large number of research was conducted to improve the effectiveness and reliability of the underground wireless communication systems in literature. In this paper, we first propose to replace the conventional lumped communication system, with the distributed network system. We also demonstrate a software-defined adaptive networking scheme. This scheme enables the automatic re-configuration, when some links or nodes fail in the network. At the same time, the routing strategy based on field strength is provided and the simulation verification is carried out. The results show that the proposed strategy can avoid the inefficient information exchange in the network, and significantly prolong the network life cycle. In addition, we propose an accumulative reception method, coupled with a multi-node co-transmission technique, that significantly improve the transmission reliability. The method is derived mathematically and verified by numerical simulations. The results show that the signal-to-noise ratio at the receiving end is improved, leading to a more reliable communication. The transmission throughput can be maximized when downhole accidents occur. These technologies lay a solid foundation for a more intelligent, efficient and reliable next generation underground wireless communication system.
