摘　　要：Multiple-Input Multiple-Output(MIMO)是水下传感器网络(Underwater Sensor Networks,UWSNs)性能改进的重要技术。然而受水下通信条件限制,MIMO技术的实施存在极多障碍。协作MIMO为UWSNs实施MIMO通信提供了新的研究途径。设计了一种UWSNs网络协作MIMO通信方法,阐述了网络部署模型,多跳协作通信架构,协作MIMO能耗模型,网络性能仿真与优化算法,网络测试平台的开发和协作MIMO节点的试制,相关的实验仿真等内容。通过研究,期望验证水下传感器网络协作MIMO技术的可行性、合理性及有效性,为部署高速可靠UWSNs网络提供理论和技术支撑。As an important technique, MIMO is used to improve communication performance of Under- water Sensor Networks （UWSNs）. However, there exists a huge obstacle on implementation MIMO communication for UWSNs, which restricts by actual communication conditions in underwater environ- ment. The communication based on cooperative MIMO offer an innovative approach for UWSNs. In this paper, we design cooperative MIMO Communication for UWSNs, describe the deployment model, the architecture of multi-hop communication, the mathematical model of energy consumption, the network performance simulation, optimization algorithm, the development of test platform and trial production of cooperative MIMO node in details. Through this study, we aim to verify the feasibility, rationality and validity of the cooperative MIMO technology for UWSNs in order to provide a theoretical and technological support for the deployment of high-speed and reliable UWSNs.
