Embodiment Construction

[0064] The underwater sensor network routing protocol based on dynamic network hole avoidance of the present invention will be described in detail below in conjunction with examples and accompanying drawings.

[0065] The underwater sensor network routing protocol based on dynamic network hole avoidance of the present invention simulates the actual underwater ocean current environment and models the node movement model. Considering the remaining energy of the sending node and the candidate node, a comprehensive selection strategy for the next hop node is designed. The underwater nodes are clustered, and the network changes caused by low node energy or topology changes are dynamically handled in different regions.

[0066] The underwater sensor network routing protocol based on dynamic network hole avoidance of the present invention comprises the following steps:

[0067] 1) Model the movement mode of each node underwater, so that the node can move regularly on a spherical sur...

Abstract

A routing protocol for underwater sensor networks based on dynamic network hole avoidance, including: modeling the movement mode of each node underwater, so that the nodes can move regularly on a sphere; establishing a network between nodes from top to bottom The virtual routing path bypasses the network hole area; forwards the data packet through the established virtual routing path; and dynamically rebuilds the path according to the topology change caused by the movement of the node. The underwater sensor network routing protocol based on dynamic network hole avoidance of the present invention can realize higher network coverage, higher data packet delivery rate, shorter transmission delay and lower energy consumption. It can efficiently deal with the problem of network holes, reflecting the robustness.

Description

technical field [0001] The invention relates to a routing protocol. In particular, it involves a routing protocol for underwater sensor networks based on dynamic network hole avoidance. Background technique [0002] The underwater sensor network contains a large number of sensor nodes arranged in a specific underwater environment. These nodes are anchored to the bottom of the water through ropes, so that the nodes can float within a certain range with ocean currents. These sensor nodes can monitor and collect various environmental parameters around the area they cover. And the depth of its location can be obtained through the pressure sensor. All sensor nodes self-organize into a network, and transmit the monitored data to the base station on the water surface through the network. Today, underwater sensor networks as a powerful technology are playing an important role in the monitoring, measurement, monitoring and control of the ocean. This technology is widely used in ...
