N2 - Fatigue monitoring is an important measure for maintaining the safety and integrality of deep-water marine risers, whose difficulty lies in highly efficient data transmitting of fatigue parameters at multi-measuring points. PCSTR (parallel cooperative spatial time reuse) method was proposed to meet the said problem. Initially, the PCSTR method, which based on the reliable data transmission with long distance for fatigue parameters of single measure point of deepwater riser, achieves efficient data transmitting of fatigue parameters by means of packet parallel transmitting, node cooperating and packet fusion. Meanwhile, the performance of PCSTR has been assessed by transmission delays, throughput and total energy consumption. Finally, trials were carried out to verify the PCSTR's performance. Numerical simulation results showed that the proposed PCSTR method outperformed significantly TDMA in terms of timeliness and energy consumption. The feasibility of underwater cooperative communication was verified via a pool trial. Thus, PCSTR is an effective method for efficient data transmitting at multi-measuring points in deep-water riser fatigue monitoring.
