一种能量均衡的水下无线传感器网络覆盖空洞修补方法OACSTPCD

In view of the existing methods for repairing holes in underwater wireless sensor networks that require hole boundary detection,high communication and computing costs,poor coverage and energy balance,and overly idealized un-derwater environment models,a multi-dimensional virtual force model based on energy between nodes,regional boundaries,zero energy holes,low energy covering holes,underwater terrain and obstacle forces was established considering the com-plex underwater terrain and large obstacles.A void repair algorithm based on the above virtual force model and energy equalization is proposed.This algorithm does not require precise cavity boundary detection and has good adaptability and robustness to complex underwater terrain and different environments.In addition,the proposed strategy of redundant patc-hing of low-energy nodes and low-energy coverage holes significantly improves the equalization of the network energy distri-bution after patching,reduces the frequency of new coverage holes due to the rapid depletion of the energy of low-energy nodes,reduces the frequency of hole patching,and reduces the network maintenance cost.
