Abstract

The invention discloses a cross-layer data transmission method based on a columnar cellular underwater sensor network. A columnar cellular three-dimensional partition structure is provided for the first time. According to the three-dimensional partition structure, a time diversion multiple access (TDMA) technology, and cross-layer combination of a cluster structure routing protocol and an opportunistic routing protocol are employed. According to the columnar cellular partition structure, the formation of crossed sound wave transmission paths can be effectively suppressed; signal transmission paths are guaranteed to be effectively spaced; sound wave signal interference is reduced; and communication performance of the network is improved. According to the time diversion multiple access technology, data transmission time slots of each region can be flexibly allocated, and channel occupation time of underwater sensor nodes is optimized. Through combination of the cluster structure routingprotocol and the opportunistic routing protocol, variability and unpredictability of an underwater environment and a high delay characteristic of the underwater sensor network can be adapted.

Description

technical field [0001] The invention belongs to the technical field of cross-layer communication of underwater wireless sensor networks, and in particular relates to a cross-layer data transmission method based on columnar cellular underwater sensor networks. Background technique [0002] A typical problem that restricts the communication performance of underwater sensor networks is the signal interference of acoustic wave communication. Signal interference stems from the non-directional nature of wireless communication. When wireless terminals with the same transmission space send and receive data at the same time period, signal interference can be caused, resulting in data conflicts. [0003] Aiming at the signal interference problem of underwater sensor network, the main focus of recent research is the design of anti-interference network layer routing protocol and the design of data link layer MAC (Media Access Control) protocol. The former research approach is to optimi...
