A glider-assisted failure link repair method

Abstract

The invention relates to a glider-assisted repairing method for a failed link, which includes: a cluster head node is responsible for collecting and processing all cluster members in the cluster and data packets sent by the glider, and sending the data to the water surface convergence node. The routing table of the cluster head should be All routing information in the area is stored, and the route to each sensor node is based on the shortest path. The glider in this area will periodically approach the cluster head node and forward the collected environmental data to the cluster head. The cluster head will transmit the link interruption information between the entire cluster members to the glider, so that when a certain link fails, the glider can repair it in time; when the cluster head sends a link repair command to the glider, the corresponding glider is used to assist the failure. The link repair path optimization algorithm enables the glider to calculate the optimal destination according to the received position of the failed link and the position of the glider itself, combined with the motion characteristics of the glider, and then complete the link recovery.

Description

technical field [0001] The invention relates to the technical field of underwater acoustic communication, in particular to a path optimization method for glider auxiliary link repair. Background technique [0002] With the development of the ocean, underwater sensor networks are increasingly being used in commercial, environmental protection, and military fields, such as: marine data collection, environmental pollution detection, coastline development, disaster prevention, auxiliary navigation, and military reconnaissance etc. However, for some research fields that require high precision and military fields that require high real-time monitoring, the current remote sensing technology and local sensing technology cannot meet the requirements. Therefore, an underwater acoustic sensor network that deploys sensor nodes that can use underwater acoustic communication in the water body that needs to be monitored has emerged as the times require. However, the complex underwater ac...

Problems solved by technology

These time-varying factors will temporarily degrade the link quality, and in severe cases, the communication link will be interrupted and the network connectivity will be reduced.

If you wait for the link environment to return to its original state, it will inevitably cause a long-term link interruption, resulting in a large transmission delay and a waste of network resources.
