A multi-buoy opportunistic routing method for underwater acoustic sensor network based on distance vector

Abstract

The invention belongs to the field of underwater acoustic sensor networks, and relates to a distance vector-based multi-buoy opportunistic routing method for underwater acoustic sensor networks, including: S1, several water surface buoy nodes periodically broadcast query packets to underwater nodes; S2, underwater The relay node forwards the query packet and establishes a distance vector; S3, the underwater source node receives the query packet, obtains the minimum distance vector, and sends the data packet in a broadcast manner; S4, the underwater relay node forwards the data packet; S5, repeats S4 Step until any water surface buoy receives the data packet; S6, after the water surface buoy node receives the data packet, it coordinates among multiple water surface buoy nodes, and finally transmits the data packet to the sink node. The underwater transmission of the present invention only uses distance vector information instead of node depth information or position information, which can well solve the problem of blank areas and "detours", and is applicable to water areas where multiple surface buoy nodes are deployed.

Description

technical field [0001] The invention belongs to the field of underwater acoustic sensor networks, and relates to a multi-buoy opportunity routing method for underwater acoustic sensor networks based on distance vectors. Background technique [0002] The underwater acoustic sensor network is a very important technology in exploring the water environment, and has been widely used, such as seismic detection, oil field development, ocean observation and underwater navigation. There is a control and deployment center in the underwater acoustic sensor network, which is used to collect the data information of each underwater sensor node, thus forming a sensor network. Therefore, the routing mechanism setting and data transmission from underwater sensor nodes to surface buoy nodes is an important auxiliary technology for underwater applications. [0003] Due to the unique characteristics of the underwater acoustic environment, underwater acoustic sensor networks face many challenge...

AI Technical Summary

Problems solved by technology

[0005] Existing opportunistic routing methods for underwater acoustic sensor networks often make forwarding judgments based on depth information or geographic location information. On the one hand, the complexity of the equipment is increased, and on the other hand, the problem of blank areas cannot be avoided.

Although there are some solutions to the blank area problem, the overhead of signaling interaction increases, and the use of
