摘要: 针对卫星通信网络规模不断扩大而卫星资源总量受限导致卫星通信资源紧缺的情况,提出一种基于定价机制的虚拟资源共享分配策略。根据微观经济学理论中边际成本的思想建立用户成本的分段函数模型,通过模型求解得出用户请求的总成本并将其上传至资源分配模块,结合定价机制达到资源利用的最大化和用户请求成本的最小化。仿真结果表明,该策略能提高卫星网络资源利用率及分配公平性,最大限度地实现资源的潜在价值。

Abstract: The conflict between scaling satellite communication network and limited resources for satellites has led to communication resource shortage.To address the problem,this paper proposes a virtual resource sharing and allocation strategy based on a pricing mechanism.The strategy builds a piecewise function model of user costs based on the perception of marginal cost in microeconomics.The total cost of user requests is obtained by the model,and uploaded to the resource allocation module.On this basis,the strategy introduces the pricing mechanism to maximize resource utilization and minimize user request costs.Simulation results show that the proposed strategy can improve the resource utilization rate and allocation fairness for satellite network,making the most of potential value of resources.

Key words: resource allocation, resource utilization rate, dominant resource, fairness, pricing mechanism
