针对水下无线传感器网络（Underwater Wireless Sensor Network，UWSN）的高效路由环境，在不使用现有的地基环境下的射频（Radio Frequency，RF）逼近方法的基础上，提出了一种考虑海洋环境下水声通信和节点运动的水下直接扩散（Underwater Direct-Diffusion，UDD）逼近方法。采用兴趣、梯度、强化三种事件的数据传输方法，通过以下方法保证兴趣的可靠性和最大化能量效率; 1）将整个网络划分为顶层、中间层和底层，以最小化不谨慎洪泛的干扰; 2）禁止同层之间的水平查询，并且仅允许不同层之间的查询，以通过泛洪传输来最小化能量消耗; 3）在由于网桥节点故障而丢失传输路由的情况下，将传输委托给同一层中的非网桥节点。
For the efficient routing environment of Underwater Wireless Sensor Network (UWSN), this paper proposes Underwater Direct-Diffusion (UDD) approach method in consideration of acoustic communications and movement of nodes under ocean environments without using existing RF (Radio Frequency) approach method in the ground-based environments. The data transmission method with the three types of events such as Interest, Gradient, and Reinforce will assure the reliability and maximize energy efficiency of the Interest by following methods; 1) to divide a whole network into top layer, middle layer, and bottom layer to minimize the interference by indiscreet flooding, 2) to prohibit the horizontal query between same layer, and only allow the query between different layers to minimize the energy consumption by flooding transmission 3) to delegate transmission to a non-bridge node in the same layer in case of losing a transmission route by a bridge node’s failure.
