摘要
针对当前水声网络研究大多基于网络仿真的现状,本文在青海湖真实的水下实验床上对LB-AGR路由协议进行实现、测试、分析与优化。针对测试过程中出现的节点层级计数至无穷以及Sink节点状态死锁等问题,通过设置计时器、改进节点状态判别等措施进行设计优化,并对优化后的协议重新测试。测试结果表明,优化后的LB-AGR路由协议能较好地解决层级计数至无穷以及Sink节点状态死锁问题,且能快速、稳定地完成水下数据的多跳传输。
Aiming at the current situation that the research on underwater acoustic network are mostly based on simulation, the LB-AGR protocol is implemented, tested, analyzed and optimized on the real time monitoring test-bed of Qinghai lake. Further we analyze the problems arose in the procedure of experiment: counting to infinity of node’s level and status deadlock of Sink node. Design optimization is carried out by setting timer and improving the implement scheme of LB-AGR protocol, and the optimized protocol is retested. Test results show that the optimized LB-AGR scheme not only solves the problems of counting to infinity of node’s level and status deadlock of Sink node, but also delivers data more quickly and stably.
