[Abstract]:Mine safety monitoring plays an important role in ensuring mine safety and production. It is difficult to ensure the efficient and stable transmission of all kinds of data and information in its complex environment. It is necessary to improve the rationality of information network distribution and adapt to environmental changes to ensure network stability. Reliable and efficient transmission performance. Wireless sensor network, as an important technology platform of wisdom mine, realizes the monitoring and control of the target at the bottom of the network, effectively solves the application target of the last kilometer of wireless transmission. The characteristics of easy deployment and fast networking make it more suitable for the application of complex underground environment. This paper aims at the characteristics of underground coal mine environment and the requirements of wireless sensor network in underground application, and combines the self-organization characteristics of wireless sensor network. The cross-layer design technology is used to study the underground network networking and routing technology to make it more suitable for the influence of the underground environment change on the network and the application needs of the users. To improve the efficiency of data transmission in the network system. The main research work includes: (1) aiming at the narrow spatial structure and complex environmental characteristics of underground roadway, In this paper, the problem of "energy hole" in wireless multi-hop network data transmission is analyzed from the aspect of data transmission asymmetry, and a cross-layer WSN routing protocol with balanced energy consumption is proposed. The effective generation density of cluster head deployed in roadway is calculated by modeling. Using cross-layer design, the link available bandwidth and node load capacity of the next hop routing node are considered as the important factors to select the routing node. It is balanced from the topology structure of the backbone node in the upper layer of the network and the selection of the routing node. Data transmission. The simulation results show that the UCR protocol realizes the non-uniform distribution of the cluster head nodes. Balancing energy consumption in different areas of the network, improving network throughput and transmission rate, more suitable for large-scale deployment of underground roadway sensor node data transmission. 2) aiming at the serious wireless channel fading characteristics of coal mining face. A clustering protocol for channel fading is proposed. Firstly, dynamically adjusting the window of the random number of nodes to ensure the optimal number of cluster heads per round. Secondly, the channel efficiency between the node and the base station is obtained by detecting frames. Based on the residual energy information of nodes, a clustering protocol for adaptive channel fading is designed as the basis of cluster preference. Finally, The simulation results show that the network topology of PEAFC-CL protocol is stable, and it has strong adaptability in signal fading environment, which effectively prolongs the network lifetime. In order to meet the data transmission requirements of various types of business underground and adapt to the influence of complex environment on the network, the packet loss rate of the network is reduced. This paper proposes a multipath routing decision protocol based on intuitionistic fuzzy set (QoS) attribute constraint for multipath routing. Using cross-layer technology to ensure that the multipath routing can meet the requirements of QoS at least based on multi-path routing. By using intuitionistic fuzzy set theory, the advantages and disadvantages of multiple parameters in the multipath are normalized, and the multi-parameter multipath routing decision matrix is established. The weight of each parameter is calculated objectively by using the information entropy theory. The TOPSIS method is used to determine the advantages and disadvantages of multipath. The results show that FFM QMRP protocol can effectively solve the multi-path optimization problem under multi-parameter constraints, with low computational complexity and low network control overhead, which is more suitable for the multi-service requirements guaranteed by QoS in congested network environment.
