Embodiment Construction

[0080] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:

[0081] Such as figure 2 and image 3 As shown, in the cell, the wireless access point is located in the center of the cell and is denoted as the sink d, the mobile terminal MT with uplink transmission demand is denoted as the source s, and there are J idle terminal nodes as relays, respectively denoted as r j (j∈{1,2,...,J}); when the power of source s is low or the quality of the uplink channel is poor, source s uses idle terminal nodes to forward data for it; when the data is completely forwarded to wireless After the access point, the source s pays the electronic currency to the relay; the transaction information of the electronic currency and the credit value of the terminal node are written into the block, and the block inform...

Abstract

The invention relates to a cell relay cooperative communication method based on a block chain smart contract, which solves the defect that it is difficult to establish a trust relationship between a cooperative communication terminal and a relay node compared with the prior art. The invention includes the following steps: establishing a relay cooperative communication system model; and performing relay cooperative communication. The invention utilizes the block generation and consensus process to ensure fair transactions between terminals and improve the security level of data transmission; the relay selection process of the information source during cooperative communication adopts the optimal transmission power and pricing algorithm selection This ensures the communication quality of the terminal under low power conditions.

Description

technical field [0001] The invention relates to the technical field of wireless cellular communication, in particular to a method for relay cooperative communication of a cellular cell based on a block chain smart contract. Background technique [0002] With the development of software and hardware of intelligent terminals, the improvement of network speed, and the development of multimedia applications, the data traffic of mobile terminals has exploded, which has brought about more and more energy consumption of mobile terminals. Energy saving and green communication are one of the important themes of wireless communication. At present, the battery performance of smart terminals has not been improved, so how to reduce the energy consumption of terminals is a key problem that needs to be solved. Existing studies have shown that cooperative communication is one of the effective methods to reduce MT energy consumption of mobile terminals. However, these studies are all based ...
