Research on water surface gateway deployment in underwater acoustic sensor networks

In the underwater sensor network, the deployment of multiple water surface gateway can effectively improve the network capacity, reduce the network delay and save the energy of underwater sensor nodes. Due to the underwater sensor nodes is easily affected by ocean currents affect which occurred in the position drift, surface gateway deployment locations need regular dynamic optimization and update. This paper designs an improved cuckoo optimization algorithm, to achieve a fair and efficient surface gateway layout optimization. At the same time, the influence of different gateway quantity on network capacity and network delay is simulated, which provides scientific decision support for the overall optimization of underwater sensor networks.
