This paper presents an original probabilistic model of a hybrid underwater wireless sensor network(UWSN),which includes a network of stationary sensors placed on the seabed and a mobile *** mobile gateway is a wave glider that collects data from the underwater network segment and retransmits it to the processing *** authors consider the joint problem of optimal localization of stationary network nodes and the corresponding model for bypassing reference nodes by a wave *** optimality of the network is evaluated according to the criteria of energy efficiency and *** influence of various physical and technical parameters of the network on its energy efficiency and on the lifespan of sensor nodes is *** analysis is carried out for networks of various scales,depending on the localization of stationary nodes and the model of bypassing the network with a wave *** a model example,the simulation of the functional characteristics of the network for a given size of the water area is carried *** is shown that in the case of a medium-sized water area,the model of“bypassing the perimeter”by a wave glider is practically feasible,energy efficient and reliable for hourly data *** the case of a large water area,the cluster bypass model becomes more efficient.
