Abstract: Background

In the data acquisition system for a nuclear physics experiment, the energy consumption of each acquisition node of wireless sensor networks is not balanced, and the energy utilization of the system is insufficient, which cannot satisfy the task of reliable data acquisition for a long time.

Purpose

This study aims to solve the common problem of energy imbalance of wireless sensor networks, and put forward a transformation scheme of power supply system for wireless sensor networks.

Methods

On the basis of reserving wireless sensor communication, the scheme achieves two improvements by adding power lines between sensor nodes. Firstly, the energy transfer channels between nodes are increased to solve the problem of unbalanced energy consumption between nodes. Secondly, on the basis of energy balance, sensor nodes communicate with the optimal energy scheme to avoid energy waste caused by frequent clusters in traditional wireless sensor networks.

Results

The results show that this method can prolong the life of the system about five times at the cost of connecting a few power lines.

Conclusion

The simulation results show that compared with clustering protocol, this scheme can reduce the average power consumption of nodes by 78% and prolong the system life by about 5 times.
