However, this algorithm with routing planning process has poor performance when the network node is unstable. When the next hop node of a node suddenly fails or is moved after the routing algorithm is calculated, then the node will send data when it sends data. Failure, which will cause the entire network node to participate in the routing process

Embodiment Construction
[0038] The following further describes the embodiments of the present invention in conjunction with the drawings:
[0039] Such as figure 1 As shown, the distributed robust routing method for the wireless network of a fully mechanized mining face of the present invention uses wireless nodes for data transmission, and the steps are as follows:
[0040] a. The wireless nodes in the fully mechanized mining face are arranged in order, that is, the numbers are allocated according to the distance from the upper and lower grooves, and the data sending node and the data final delivery node are selected according to the needs. When the data sending node number and data finally reach the node When the numbers are adjacent, the data sending node directly establishes a connection with the data final delivery node and transmits the data;
[0041] When the number of the data sending node is not adjacent to the number of the final data delivery node, the data sending node and the data final delive...

The invention discloses a distributed robust routing method of a fully mechanized working face wireless network. The distributed robust routing method is applied to connect the wireless network in the fully mechanized working face of mine. During the wire communication, each communication node is used for classifying the neighbour node according to the distance between the neighbour node and the upper and lower smooth grooves. Namely, each communication node is used for maintaining two neighbour node lists; each node is used for optimizing the neighbour node sending rate in two neighbour node lists according to the distance and the handling capacity of the neighbour node, the neighbour nodes are selected from two neighbour node lists and used as the destination while the data is required and sent, if the sending operation is successful, the sending task of the node is finished; otherwise, the neighbour nodes are selected and used as the destination randomly until that the data is successfully sent. The time delay shaking range capability of whole network is reduced while the communication node loses the energy, and the time delay of the algorithm and time delay shaking range are reduced while the communication node has fault.
Description
Technical field [0001] The invention relates to a distributed robust routing method, in particular to a distributed robust routing method of a fully mechanized mining face used for wireless network connection in a fully mechanized mining face in a coal mine Background technique [0002] Due to the mobility of fully mechanized mining face equipment, cables are not easy to handle during the movement of shearers and hydraulic support equipment. The use of wireless networks as communication networks can better meet the needs of face monitoring systems. There have been some research results in applying wireless network technology to fully mechanized mining face. [0003] Although the physical length of the working face is not long, the harsh communication environment of the fully mechanized mining face has seriously affected the communication distance and reliability of the fully mechanized mining face. Preliminary theoretical analysis shows that the channel attenuation coefficient of ...
