Abstract
This paper researched a mobile distributed cooperative data transmission technology based on Hoc filler energy pre-diction algorithm for underwater acoustic sensor network. Aiming at the complex underwater monitoring environment, underwa-ter wireless communication and the network topology and the dynamic characteristics, it put forward the Hoo for node energy prediction algorithm based on energy of two-dimensional table, relay selection and the establishment of a distributed data col-laboration transmission technology. The technique, according to the underwater wireless sensor nodes in wireless link broadcast properties,the Hoo filter to predict the residual energy of nodes and its geographical location, established two-dimensional ta-ble. The technique selected the best as cooperative node, and adaptively chose amplifying retransmission and decoding retrans-mission mechanism according to the radio link quality. Mathematical analysis shows that, the H∞ filter on the residual energy of nodes has higher forecast accuracy, and the cooperative transmission technology can effectively extend the underwater sensor network life cycle and improve the utilization of network resources and system throughput.关键词
