Research on 3D Dynamic Clustering Routing Algorithm Based on Cooperative MIMO for UWSN

为解决基于协作的多输入多输出(Multi-input Multi-output,MIMO)同构水下无线传感器网络(Underwater Wireless Sensor Networks,UWSN)的能量节省和能耗均衡的问题,建立了多跳分布式UWSN三维系统模型。文中弥补了DCREDT选择算法能量空间分布不均的不足,通过引入能量门限和距离算法,提出了一种基于能量和距离的带门限水下动态分簇路由算法(Underwater Dynamic Clustering Routing Algorithm Based on Energy and Distance with Thresholds,UDCREDT),同时定量分析了能耗均衡性对网络寿命的影响并确定了门限的取值方法等。通过仿真分析验证了UDCREDT算法的合理性和有效性。相比DCREDT选择算法,所提算法的能耗降低了约6.81%,均衡性提高了约7.98%,有效延长了网络的使用寿命。

In order to solve the problem of energy saving and energy balance in homogeneous underwater wireless sensor networks(UWSN)based on cooperative multi-input multi-output(MIMO),a multi-hop distributed UWSN three-dimensional system model was built in this paper.By introducing energy threshold and distance algorithm,the insufficiency of energy spatial distribution in the DCREDT selection algorithm was improved and an underwater dynamic clustering routing algorithm based on Energy and Distance with Thresholds(UDCREDT)was proposed.At the same time,the influence of energy balance on the service life of the network were quantitatively analyzed and the threshold value method was determined.Finally,the reasonableness and validity of the new UDCREDT algorithm were verified by simulation analysis.And compared with the DCREDT selection algorithm,the energy consumption is reduced by about 6.81%,and the balance is improved by about 7.98%,which effectively prolongs the service life of the network.
