Abstract

Research on sensory networks for marine environmental information acquisition has received more and more attention. However, the underwater wireless sensor network has the characteristics of limited bandwidth and energy consumption. Therefore, by using the sparseness of sensor node data in frequency domain and space domain, this paper proposes a dual-domain compression sensing (DCS) low-energy ocean environment information collection scheme. The scheme uses the sparsity of the frequency domain for information recovery, thereby further saving the control overhead of the sink node’s downstream sending address frame. Through the result of simulation, it is found that the scheme proposed in this paper is better than the previous IDMA multiple access detection scheme in terms of energy consumption.
