Underwater sensor network data collection method based on glider

Abstract

The invention relates to an underwater sensor network data collection method based on a glider, and the method comprises the stepsthat a proper sensor node is selected to collect data in a communication range in a process that the glider operates along a sawtooth-shaped track; in the data collection process, the glider carries out dynamic planning on the sensor nodes, and sensor node scheduling isoptimized; an off-line calculation and on-line scheduling mode is adopted, so that the calculation load is reduced; the Poynting exponential algorithm is improved, a threshold is set, the broadcasting frequency and the energy consumption caused by broadcasting are reduced, the communication load is reduced, and the service life of the underwater sensor network is prolonged. According to the underwater data collection method, a glider is used as a data collection platform, so that a large-range and long-time data collection task can be realized; by adopting an exponential algorithm with a threshold value, the calculation complexity of solving dynamic programming is reduced, the communication consumption is reduced on the basis of ensuring the data collection quality, the sensor schedulingis optimized, and the service life of the underwater sensor network is maximized.
