一种基于动态价格机制的资源分配算法

How operators provide QoS guarante for applications and how to make network resources fully used in heterogeneous network environment are studied in this paper. Firstly, this paper discusses the QoS properties of applications and puts forward a unified framework for utility functions to describe the functional relationship between users' satisfaction and resources allocationed to applications, and acquires the relative parameters by simulation. Then it introduces the dynamic pricing scheduling mechanism to achieve dynamic load balancing between the various networks. After that, a mathematical model is established, converting the resource optimization problem in heterogeneous network environment into a non-convex optimization problem, and using sequential quadratic programming method to solve the problem. In order to improve the convergence speed of algorithm, the initial values were selected. Finally, the stability and convergence of the algorithms are verified by theoretical analysis. The simulation results show that the method can improve the utility of the whole network and the request access rato.
