Abstract

The invention discloses a settling deploying method for underwater sensor nodes based on an ideal pattern model. The settling deploying method comprises the following steps: randomly deploying m mutually-communicated sensor nodes on the water surface of a given target region, determining the minimum number n of ideal pattern nodes required for the complete coverage and communication of the given target region, assigning a water surface node to an ideal pattern position corresponding to each ideal pattern node, setting each matched node to the depth of the corresponding pattern position, judging whether the deployed nodes form a communicated network, if no, searching network sub-regions which are not communicated, and carrying out network connectivity repairing; and finally, if redundant nodes exist on the water surface, repairing a converge cavity of the deployed network by virtue of the redundant nodes, so as to enable the redundant nodes settled from the water surface to be communicated with the underwater nodes. By virtue of the settling deploying method, the maximum coverage rate of an underwater 3D target region and full communication of the network nodes can be realized through once settling deploying of the sensor nodes.

Description

technical field [0001] The invention belongs to the technical field of wireless sensor networks, and more particularly relates to a 3D underwater wireless sensor network deployment method based on an ideal pattern model.
