A Clustering Algorithm Based on Fixed Nodes 3D Grid for UWSNs

水下传感器网络是应用于水下通信的重要传感器网络技术。提出了基于固定节点3D网格部署的水下无线传感器网络分簇算法,设计了3D网格的编址和分簇方法,实现了基于地址分配的节点定位,构建了算法的能耗分析模型。采用MATLAB完成了算法的性能仿真,对比了DS-VBF、IAR和GEDAR 3个算法的平均数据传输延迟和网络生存时间(TTL)。实验结果表明,此算法的平均数据传输延迟较短,可明显提高UWSNS的生存时间。

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.
