Problems solved by technology

However, the current research is not deep enough. For example, since the relay node may have its own business in addition to relaying the business from other nodes, how much bandwidth and energy are allocated by the relay node to transmit its own business, how much bandwidth and energy are allocated to the relay node? The use of energy for forwarding services is still a problem that needs to be studied and solved

Embodiment Construction

[0008] The wireless EH cooperative communication system model in the present invention includes a source node, several relay nodes and a destination node, and all of them have the ability to collect energy. The technical solution of the present invention considers two situations, one is to consider the resource allocation problem when both data and energy can be transferred between the relay node and the destination node, the other is to consider only the energy between the relay node and the destination node Resource allocation issues when transferring.

[0009] (1) Resource allocation when both data and energy can be transferred between the relay node and the destination node.

[0010] define x n is the own service transmission rate of relay node n; y n is the relay service transmission rate of relay node n; z n is the energy collection rate of the relay node n; t n is the energy transfer rate of the relay node n; λ n is the price paid by relay node n for the transmissi...

Abstract

The invention discloses a data and energy cooperation method based on a price mechanism. According to the price mechanism, the invention realizes the data and energy cooperation method of bandwidth and energy allocation by solving optimization problems, and achieves the purpose of optimizing system performance. In addition to solving the problem of node bandwidth and energy allocation, the present invention can also be used to solve the problem of relay selection in a wireless EH cooperative communication system, and has wide applicability.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a data and energy cooperation method of a cooperative communication system. Background technique [0002] Growing concerns about the energy consumption of wireless networks and rising Earth's temperature have prompted the development of more energy-efficient communication technologies. Energy harvesting (EH) technology, which obtains energy from renewable energy sources such as solar energy, wind energy, thermal energy and radio frequency (RF) energy, can drive communication devices and networks, showing bright prospects for realizing green communication. [0003] In the wireless EH communication system, two-way cooperative transmission of data and energy between two nodes A and B with EH capability is currently studied. Data or energy can be transmitted from node A to node B, and can also be transmitted from node A B transmits data or energy to node A. I...
