Embodiment Construction

[0069] Below we illustrate how IPool-ADELIN works in a collaborative scenario.

[0070]1) In cooperative scenarios (such as figure 2 shown), select the algorithm according to the distance according to the ADELIN method, that is, according to the two distance reference lines θ 1 and θ 2 (θ 1 2 ) selection, it can be seen that Algorithm 1 is selected here.

[0071] 2) The upstream node, that is, the transmission node S queues up all its neighbor nodes randomly.

[0072] 3) Transit node S selects and notifies node R to become a temporary IPool node.

[0073] 4) The transmission node selection algorithm (that is, Algorithm 1) sends out the data packet, and the downstream node D and the IPool node R receive the data packet.

[0074] 5) Judging whether a group of data packets have been sent, if not, then proceed to step 6), if not, proceed to step 11);

[0075] 6) Downstream node D and IPool node R receive the data packet broadcast by the upstream node, node D first performs B...

Abstract

The invention provides a method for improving reliability of data transmission of an underwater acoustic sensor network. The method comprises the following steps that: an upstream node randomly queues up all neighboring nodes thereof, takes the head node of the queue as a temporary IPool node, transmits data packets and judges whether a group of data packets are transmitted; a downstream node and the IPool node are connected with the data packets broadcast by the upstream node; the IPool node monitors the data packets forwarded by the downstream node and compares the data packets with a cache data packet; and the downstream node counts, decodes, verifies, recodes and forwards the data packets received by the IPool node and judges whether one group of data is received from a temporary IPool node again and whether all the data packets are transmitted. For the problems of increased energy consumption, channel occupation and data transmission delay caused by the prior art, the method reduces the energy consumption of the data transmission on the premise of not reducing the reliability of the data transmission and can meet the requirements of the underwater acoustic sensor network on actual practice better.

Description

technical field [0001] The invention relates to a data transmission method of an underwater acoustic sensor network, which belongs to the technical field of computer wireless network applications. Background technique [0002] The underwater acoustic sensor network is a wireless sensor network composed of various underwater sensor nodes, which uses underwater sound as the communication medium and aims at ocean monitoring. Compared with land-based sensor networks, underwater acoustic sensor networks have unique characteristics such as small bandwidth, high transmission error rate, time extension, and high energy consumption. These characteristics make it very challenging to study reliable data transmission methods. In general, feedback or redundancy is the most commonly used data transmission reliability technique [1] . [0003] To the best of our knowledge, current research on the reliability of data transmission in underwater acoustic sensor networks [2，3] a bit less. A...
