| 摘 要： | 水下传感网络是开发水域环境的有效技术手段。但在水下环境传输数据，信号衰减快，通信链路质量差，降低了数据包传递率。提出基于链路质量和位置的协作(LQLC)路由。LQLC路由引用协作路由思想，利用链路质量和节点能量信息，构建候选转发节点集；再从候选转发节点集中选择具有最优链路质量的节点作为转发节点；最后在候选转发节点集中选择离转发节点最近的节点作为协作节点。仿真结果表明，提出的LQLC路由提高了数据包传递率。

| Abstract: | Underwater Sensor Networks(USNs) technique is an effective way to develop water environment. However, when data is transmitted in the underwater environment, the signal attenuation is fast and the quality of communication link is poor, which reduces the packet transmission rate. Therefore, Link Quality and Location-based Cooperative(LQLC) routing is proposed. It refers to the idea of cooperative routing, which first uses the link quality and node energy information to build candidate forwarding node set, and then selects the node with the best link quality as the forwarding node from the candidate forwarding node set. The nearest node to the forwarding node is selected as the cooperative node in the candidate forwarding node set. Simulation results show that LQLC protocol has a good performance in terms of packet delivery ratio. |
