Problems solved by technology

However, the constant routing pipeline radius threshold has a significant impact on the performance of VBF, and it may not be possible to find a suitable next-hop node only in the pipeline, especially in sparse underwater networks, so it is necessary to design a solution to get rid of the constraints of the pipeline

Embodiment Construction

[0050] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0051] The invention realizes an adaptive probabilistic forwarding underwater routing protocol named APFP. APFP considers the impact of the forwarding area on the communication range of nodes, and divides the network scene into two hemispheres. Nodes in the network area determine which partition they belong to based on their geographic location information, and different partitions use different forwarding probabilities.

[0052] Step 1: Each node in the network maintains two routing tables Q1 and Q2. Q1 records the data DATA to be transmitted by the node and the waiting time HT of the node; Q2 records the sent data packets and the data packet numbers.

[0053] Step 2: The source node A has data to send, but the source node does not have a route to the destination node. At this time, the route discovery process is started; the source node obtains its ...

Abstract

According to the self-adaptive probability forwarding routing protocol of the underwater acoustic sensor network, the greedy progress is maximized, the efficiency of the forwarding set selection method is improved, the result of efficiently forwarding data packets is finally achieved, and it can be seen from the result that the proposed protocol maintains low energy consumption. The method is suitable for a sparse and topology-variable underwater network environment. The method comprises the following steps: firstly, dividing a forwarding region into a forwarding region and a non-forwarding region; compared with existing opportunistic routing transmission, the method has the advantages that waiting time is saved, end-to-end delay is greatly reduced, candidate set node selection is consistent, node selection fairness is guaranteed, an APFP protocol is achieved through NS2, simulation verification is conducted on the APFP protocol, and the method has obvious advantages.

Description

technical field [0001] The invention relates to the technical field of underwater acoustic sensor network and underwater acoustic routing protocol, in particular to the realization method of sparse underwater acoustic sensor network routing protocol. Background technique [0002] Underwater acoustic sensor network is a promising technology that will facilitate a wide range of underwater applications, but due to the harsh underwater environment, it faces great challenges and problems, such as limited bandwidth, node mobility, long propagation delay, three-dimensional deployment , energy constraints, expensive manufacturing and deployment costs, all of which limit the performance of UASNs routing protocols, therefore, how to design an underwater acoustic routing protocol with high forwarding efficiency becomes the key. [0003] Routing protocols for underwater acoustic sensor networks can be divided into location-based routing protocols and location-less routing protocols. Lo...
