Embodiment 1

[0050] This embodiment provides a mobile sensor intelligent trajectory design method based on sustainable data acquisition, such as figure 1 As shown, including the steps:

[0051] S1. Moving sensors collect energy from the surrounding environment and collect energy for their own movement and data transmission;

[0052] S2. Based on the model of energy collection and data transmission between Markov decision;

[0053] S3. The constructed model is solved by the depth deterministic policy gradient algorithm to obtain the optimal combined trajectory movement and energy corresponding to the power allocation strategy.

[0054] In step S1, the moving sensor collects energy from the surrounding environment and the collected energy is used for its own movement and data transmission.

[0055] The action of the moving sensor in this embodiment is to collect energy around the environment, and the collected energy is used for its own movement, so that the peripheral data is collected during mov...

Embodiment 2

[0120] A mobile sensor intelligent trajectory design method based on sustainable data acquisition is in that the embodiment of the first embodiment is in that:

[0121] This embodiment mainly verifies the effectiveness of the training algorithm.

[0122] Set a 10 × 10 two-dimensional right coordinate, wherein (x, y) is indicated in the position (x, y∈ [0, 10]) on the two-dimensional plane. Energy 1 and Energy 2 are located (0, 10) and (0, 0), respectively. MS can reposition in this area to find better energy collection and data transfer position, mobile speed, and angle definitely in [0, 1], [- π / 2, π / 2], where μ, σ represents energy The mean and variance of the random distribution, δ indicates that the mobile sensor moves consumption (ie, the energy Δ is consumed per move). Next, the effectiveness of the training algorithm (ie, algorithm 1) is verified by detecting the convergence of motion trajectory and algorithm learning of mobile sensor learning. In addition, the effects ...

Abstract

The invention discloses a mobile sensor intelligent trajectory design method based on sustainable data collection, comprising steps: S1. The mobile sensor collects energy from the surrounding environment, and uses the collected energy for its own movement and data transmission; S2. Cove decides to construct a model between energy collection and data transmission; S3. Use the deep deterministic policy gradient algorithm to solve the constructed model, and obtain the optimal joint trajectory movement and power allocation strategy corresponding to energy. Aiming at the goal of maximizing the long-term average data collection throughput, the present invention designs an algorithm so that the sensor can intelligently track the optimal arrival point under each time slot in the entire two-dimensional space area when the environmental energy is unknown, and then This time slot is used to maximize energy collection and data transmission.

Description

Technical field [0001] The present invention relates to the field of wireless information transmission technology, and more particularly to a mobile sensor intelligent trajectory design method based on sustainable data acquisition. Background technique [0002] WiReless Sensor Networks, WSN is a distributed sensor, which is sensor that can perceive and check the outside world. The sensor in the WSN communicates wirelessly, so network settings are flexible, and the device location can be changed at any time, and can also be connected to the Internet or wirelessly. Each node in the network has a sense of ecological environment monitoring, smart security patrol, forest temperature and humidity data acquisition, etc., but the data acquired by each node of the usual sensor network is facing many data transmission. Challenge, because the capacity of the sensor node is limited and the area where the entire network is deployed is generally more complicated to not conformity to the data t...
