Problems solved by technology

However, due to the unstable underwater environment, the Q value of the next hop forwarding node selection is also constantly changing and very unstable. At the same time, due to the need to calculate the Q value of the nodes in the entire network, such statistical calculations for large-scale networks will consume a lot of energy. energy

Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] A method for constructing a routing protocol for an underwater acoustic sensor network based on an asymmetric link, the steps of which include:

[0032] Step 1: Neighbor list construction

[0033] The communication links between nodes in the underwater acoustic sensor network are affected by ocean currents and node perception beams, the communication links of nodes are asymmetric, and the neighbor list is constructed according to whether the communication links between nodes are symmetric links or asymmetric links ;

[0034] like figure 1 As shown, an asymmetric link. The source node broadcasts the control packet, and the surrounding nodes reply to the confirmation information in time after receiving the control packet, and the source node confirms the neighbor node information according to the received confirmation information. If ...

Abstract

The invention relates to an acoustic sensor network route protocol construction method based on asymmetric links, comprising the steps of: first, analyzing communication links among nodes in a network are symmetric links or asymmetric links, constructing reverse paths according to node peripheral neighbor node information if communication links among nodes are symmetric links, and increasing network connectivity; second, constructing a suitable transmission path according to a node neighbor list and constructed reverse paths, a next hop of forwarding node preferentially selecting a neighbor node nearest to a Sink node in all symmetrical links, and selecting a neighbor node nearest to a Sink node in all asymmetric links if no symmetric link node exist, wherein according to the application of the reverse paths at the moment, time delay is increased and waiting time needs to be increased; and finally, optimizing and updating the constructed transmission path: mainly including removing ineffective nodes and loops, and periodically updating the transmission path.

Description

technical field [0001] The invention relates to a method for constructing an underwater acoustic sensor network routing protocol based on an asymmetric link, and belongs to the technical field of underwater acoustic sensor network communication support. Background technique [0002] In data transmission in the marine environment, it is required to reduce network energy loss and data waiting delay, so as to improve the reliability of data transmission and prolong the life of the network. In addition, due to the harsh and changeable underwater environment, the communication link between nodes often changes and fails, and the routing mechanism needs to have a certain degree of robustness. Therefore, research on routing algorithm design for marine environment has attracted people's attention. In recent years, a variety of underwater acoustic sensor network routing protocols based on different application goals have been proposed, and the routing protocols are classified and com...
