A Characterization and Construction Method of Utility Capacity Considering Multiple Network Factors

Abstract

The invention discloses a method for characterization and construction of utility capacity that takes into account multiple network factors, integrates competition and cooperation relationships, selfish rational behaviors, and different network performance indicators of multiple network users, and characterizes network capacity domains based on cooperative game and utility theory. In a high-density network, more practical factors such as the competition and cooperation relationship of multiple network users, selfish and rational behavior, and different end-to-end performance requirements affect the network capacity. The invention proposes the concept of network utility capacity, the mathematical representation and construction method of network capacity of multi-dimensional actual factors, takes into account different network performance indicators, and proposes a mathematical representation method for individual network utility; takes into account interference with competition and cooperation, selfish rational behavior, and represents the whole Network utility capacity: A construction method of network utility capacity is proposed, which takes into account multi-user behavior and network capability indicators, and divides multiple factors into selfish rationality, cooperative and non-cooperative user behavior characteristics and user location information.

Description

technical field

[0001] The invention belongs to the technical field of wireless communication, and in particular relates to a method for characterizing and constructing a utility capacity that takes multi-network factors into consideration. Background technique

[0002] The traditional point-to-point information theory constructs the capacity theory of spectrum and power resources relative to Gaussian white noise. Network information theory starts the study of multi-user network capacity. With the continuous development of current network architecture, key technologies and applications, the capacity domain of traditional point-to-point Shannon or multi-user network information theory and traditional information theory technology are facing great challenges. In the face of complex network structures and diverse wireless environments, they cannot provide effective theoretical support for network design. Therefore, safety capacity, post-Shannon functional capacity, and transm...
