Aiming at the problems of low node mobility and poor localization accuracy in underwater acoustic sensor network(UASN)
a localization algorithm based on mobile node prediction for UASN is proposed.Firstly
a motion model of UASN is constructed based on the characteristics of UASN and tides.Secondly
a ranging strategy based on time of arrival(TOA) is proposed to reduce communication costs and energy consumption
and the grey wolf optimization(GWO) algorithm is used to find the optimal position of secondary nodes with low localization accuracy.Finally
the proposed algorithm is simulated and analyzed.The simulation results show that the proposed algorithm not only effectively reduces network energy consumption
but also improves network location coverage and node localization accuracy.
