Embodiment Construction

[0021] The embodiment of the present invention will be described below with reference to the accompanying drawings.

[0022] figure 1 It is a total flow chart of energy optimization routing scheme suitable for multi-jump reversing networks, including: modeling multi-jump routing, forwarding area selection, dynamic adjustment routing metric, irregular stable point, relay node selection The optimal path.

[0023] figure 2 Modeling the routing problem of multi-jump reversing. By transmitting RF waveforms by radio frequency, the nodes within the range of radiation range can be energy from the RF signal. Node A wants to communicate with node D, but D is not within its reverse scattering transmission range. Node A first obtains incident energy from the RF source, then reflects the information back to the candidate node B or C. When B or C receives information from A forwarded, it will continue to reflect into the candidate node D. Repeat this step each time you go until you reach your...

Abstract

The invention relates to an energy optimization routing protocol applied to a BackCom network, which is used for modeling a multi-hop routing problem aiming at a short communication distance. Different forwarding areas are selected for the nodes according to different backscattering transmission ranges of the nodes; an energy optimization routing metric is set by considering node positions and node residual energy in a one-hop range; aiming at different energy obtained by the nodes, according to the distance between the nodes and the radio frequency source, the routing metric weight is dynamically adjusted to balance energy balance and energy efficiency requirements of different areas; a stable area is provided, and stable area nodes replace stable points irregularly through cooperation. The protocol aims to solve the problems of network life and energy consumption of long-distance backscatter communication.

Description

Technical field [0001] The present invention belongs to the field of reverse scattering communication, and the proposed routing scheme can improve the balance and effectiveness of energy, and is an energy optimization routing method suitable for reverse scattering communication networks. Background technique [0002] Due to low power consumption, reverse scattering communications (Backcom) has become a very promising technology in the most recent Internet of Things. However, Backcom has a unique communication characteristic, such as a short communication distance, and the reverse scattering range of nodes are different, and the energy acquired by different region nodes is different. At present, the routing protocol under reverse scatter is less research, and the existing routing protocol mainly considers fixed path and reliability, rather than energy consumption. [0003] The present invention considers the balance and effectiveness of energy. First model the routing problem of m...
