Abstract: 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.

Key words: underwater acoustic networks, LB-AGR, test-bed, level of node counting to infinity, status deadlock
