The invention discloses a distributed opportunistic routing method for an underwater sensor network based on photoacoustic fusion, including: (1), nodes to transmit observation data information select one of the transceiver intervals as the working transceiver interval; (2), Transmit test data packets by optical communication; (3), other nodes that receive the test data packets calculate their information metrics; (4), send data packets in the working transceiver interval; (5), in order of priority , if the node with high priority successfully receives the data packet, it will be selected as the winning node, and the winning node will transmit a confirmation signal in the form of acoustic communication broadcast; (6), if the winning node is a sink node, the water The next communication is completed, otherwise, the winning node will be the node to send data, and return to step (1). This method utilizes the advantages of underwater optical communication and acoustic communication technology, and selects the best existing technology for transmission according to the physical location information of nodes and the channel occupancy in the network.
Description
Technical field [0001] The present invention belongs to the field of underwater wireless communication technology, specifically, relates to a distributed opportunistic routing method based on an underwater sensor network based on photoacoustic fusion. Background [0002] The current construction of underwater wireless sensor networks mainly relies on underwater acoustic communication technology. Underwater acoustic communication is a practice-proven and widely accepted technology with the advantages of omnidirectional propagation, long transmission distance, and reliable quality, and has been adopted by many commercial, scientific and military applications. Emerging underwater high-capacity high-speed communication applications (such as high-resolution images, real-time video acquisition, etc.) have high transmission rate requirements and require high-speed, long-range and low-latency underwater network solutions. On the one hand, due to the limitation of the available bandwidth...
