Document Type and Number:
WIPO Patent Application WO/2019/000851
Kind Code:
A1
Abstract:
Disclosed is a game theory-based relay selection and power distribution method in a smart power grid, applicable to a relay network system. The system comprises a source node, a destination node, and a relay node. Under the condition of each relay quotation, the user modeling is that a purchaser takes the maximum utility as the rule to select an optimal relay and optimal purchase power, and the relay modeling is that a seller determines a selling price strategy according to different cost prices provided by the smart power grid to obtain the maximum profit. After continuous game iteration, the user's selection of a relay, the optimal power distribution and the quotation of the relay finally do not change again, i.e., reaching a Nash equilibrium point. The present invention can effectively improve the transmission rate while taking the profits of the user and the relay node into account, is smaller in calculation burden, and is high in convergence rate.
