摘要：
In the network environment of underwater passive locating node, when the anchor nodes are always in a state of activation and keep corresponding with buoy nodes, the limited energy of the nodes will be exhausted rapidly and lead to some problems such as network fault and nodes death. Therefore a special improved low energy self-healing algorithm of selecting the best anchor node based on tetrahedron similarity was proposed in this paper. When a failure occurs, a new substitution anchor node will be selected in backup candidate nodes in real time. This substitution node will be aroused as a new node to choose the recovery path adaptively and ensure the smooth real-time transmission of the data. The simulation results show that this algorithm reduced the death number of the nodes and the rate of network faults. It shows good performance in terms of survival number of nodes, network traffic, and the prolongation of network lifetime.
