水声传感器网络近年来受到了广泛的关注。水声传感器网络的一个重要特点是，大多数水声传感器节点都具有一定的波束宽度和三维方向，而现有的水声路由协议忽略了这一点。这一特性将导致现有协议性能的急剧下降。我们开发了一个基于距离的概率路由DBPR协议来解决这个问题在UASN。DBPR使用转发概率来确定是否转发数据包。节点的转发概率受节点的距离和波束宽度的影响。我们的协议的一个关键优势是，它可以实现相对较高的数据包传输速率，并确保合理的能量消耗时，考虑到上述特性。建议的协议进行了比较，具有代表性的路由协议UASNs。仿真结果验证了所提工作的有效性和可行性。
Underwater Acoustic Sensor Networks UASNs have received significant attention recently. The important characteristic of an underwater acoustic sensor network is that, most underwater acoustic sensor nodes have a certain beam width and a three-dimensional direction, which are ignored by the existing underwater routing protocols. This characteristic will lead to the sharp decline of the existing protocol performance. We develop a Distance-Based Probabilistic Routing DBPR protocol to tackle this problem in UASNs. DBPR uses forward probability to determine whether to forward the data packet. Forwarding probability is influenced by the distance and the beam width of the node. A key advantage of our protocol is that it can achieve relatively high packet delivery rate and ensure reasonable energy consumption when taken into account the above characteristic. The proposed protocol is compared with a representative routing protocol for UASNs. The simulation results verify the effectiveness and feasibility of the proposed work.
