Abstract :
One parallel underwater acoustic network (UAN) is designed to monitor the vortex induced vibration (VIV) of free span of subsea infield pipeline in the harsh deep water environment. The architecture consist of one mater node and several source node which one kind of dense network. One underwater Orthogonal Frequency Division Multiple Access (UOFDMA) scheme is proposed to meet with the multiple access. It is solved as one optimizing problem for uplink performance of parallel UAN related to power control, frequency allocation, multiple access and fairness. The numerical simulation demonstrates that the method proposed in this paper can achieve one good performance.
