Anchor node deployment method for dynamic underwater environment

Abstract

The invention discloses an anchor node deployment method for a dynamic underwater environment. The anchor node deployment method comprises the following steps: 1, randomly deploying underwater nodes and dividing common nodes and edge nodes according to the positions of the underwater nodes to establish an anchor node model; setting N to be equal to 0; 2, broadcasting related information of each node in the anchor node model, and receiving and storing information of other nodes at the same time; 3, calculating the resultant force of the virtual force borne by each node; 4, calculating an expected moving distance between each common node and the boundary node; 5, calculating the mobile income according to the type of the node; 6, calculating the moving distance of each node along the anchorchain; 7, judging whether each node meets the condition that N is greater than or equal to 45, and if yes, exiting the program; otherwise, returning to the step 1, and enabling N to be equal to N + 1;the invention provides a mobile benefit function which comprehensively considers the node density, the node residual energy and the node moving effect, so that the unnecessary movement of the node isreduced, the node residual energy is balanced, and the purpose of reducing and balancing the energy consumption is achieved.

Description

technical field [0001] The invention relates to the technical field of underwater wireless sensor networks, in particular to an anchor node deployment method for dynamic underwater environments. Background technique [0002] As a convenient tool for understanding and understanding the ocean, the underwater wireless sensor network can enable people to obtain more ocean information, improve the ability to monitor and predict the ocean environment, and help people deal with ocean emergencies. It has a wide range of applications, such as marine information collection, environmental monitoring, deep-sea exploration, disaster prediction, auxiliary navigation, distributed tactical monitoring, etc. The premise of the above application is effective environmental monitoring of relevant sea areas and effective coverage of relevant sea areas by using underwater wireless sensor network nodes. Therefore, the deployment strategy of underwater sensor network nodes needs to increase the res...
