基于Stackelberg博弈的遥感数据实时中继传输方案
A real-time relay transmission scheme for remote sensing data based on Stackelberg game
摘要
Abstract
When a high-orbit satellite(Geostationary Orbit,GEO)is used to provide real-time relay service for a low-orbit remote sensing satellite(Low Earth Orbit,LEO),the allocation of GEO relay resources directly affects the data transmission efficiency,and at the same time,the return of transmitting the same size but different level of the task is different,which affects the overall network revenue.To solve the above problems,using the Stackelberg game model,this paper proposes a task-aware real-time relay transmission scheme for remote sensing data.First,to reasonably describe the topological changes between layers and reduce the number of link interruptions in each time slot,we determine the identity and number of LEOs participating in relaying under each time slot using the non-uniform time slot division method;second,according to the spatio-temporal attributes of remote sensing data and user needs,we utilize the naming mechanism in Named Data Networking(NDN)to name the tasks,which can realize the network's perception of the level and size of the content;finally,when multiple LEOs offload data to the GEO,a task-aware GEO resource allocation model is constructed using the Stackelberg game model,and a priority-based GEO resource allocation algorithm is proposed,where the optimal allocation of the GEO rate can be achieved according to the task priority under each time slot to maximize the benefit of the GEO,and the Nash equilibrium is proved to exist.Experimental results confirm the effectiveness of the proposed scheme in terms of pricing,GEO resource allocation,transmission efficiency,and network revenue.关键词
