Abstract：A new network deployment algorithm is proposed for the problem of low network lifetime and low network coverage of underwater sensor networks. Firstly, the node which has a higher network coverage redundancy should be asleep. Then the network coverage and energy consumption will be set as the objective functions. And the multi-objective optimization algorithm will be adopted to optimize it. At last, the TOPSIS is used to select the best solution from the Non-dominated solution set. If any node is dead, the sleeping nodes in the near dead node will be waken up to preserve the coverage. The results demonstrate that the proposed algorithm outperform the existing algorithms in terms of various performance metrics including energy consumption and the coverage.
