英文摘要：

UWSNs （Underwater wireless sensor networks） is one of the important sensor networks technologies for underwater communication. In this paper, a clustering algorithm based on fixed nodes 3D grid for UWSNs is proposed, and then design the addressing format and clustering method. We realize the sensors location schema based on the address allocation, and then build the energy consumption model. At last, we analyze the performance of the algorithm by MATLAB, compared the data transmission delay and rITL values of DS-VBF, IAR, GEDAR. The experimental results show that the average data transmission delay of the proposed algorithm is relatively low, and the survival time of UWSNS can be improved obviously.
