A wireless sensor network implementation method based on channel and power dynamic adjustment

Abstract

The invention disclosed a wireless sensing method based on channel and power dynamic adjustment. On the basis of the original IEEE 802.15.4 protocol, increase the reference door limit of BER and the reference door limit for receiving power on the application layer.And the control module of the power dynamic adjustment step, the dynamic adjustment of channels and power through this module.The beneficial effect achieved by the present invention: The present invention implements the wireless sensing network communication function that can be used in the smart grid industry based on the IEEE 802.15.4 protocol.The invention has dynamically adjusted the wireless channel and transmitting power, which not only meets the anti -interference requirements of communication between the wireless sensing network nodes, but also reduces the battery power consumption as much as possible.

AI Technical Summary

Problems solved by technology

At the same time, the wireless sensor network is a resource-constrained application network, and the energy, storage capacity and computing power of the nodes are limited.

In addition, various interference factors also affect the reliability of data transmission

All of these lead to the fact that the existing mature network protocols used in traditional wireless networks are not suitable for wireless sensor networks, so it is necessary to design resource-efficient (especially energy-efficient) and anti-interference wireless sensor network protocols for specific applications.
