摘要: |
目前空间信息网络中卫星资源不尽相同,且卫星节点的星间链路动态变化,给资源映射造成困难,使得网络资源利用不充分.如何实现空间资源利用的最大化,成为亟待解决的难题.为解决上述问题,提供了一种方法:首先,将卫星网络可以提供的资源和任务指标映射表达为多维矢量;再通过线性规划,使资源矢量和任务矢量相匹配,从而使网络资源能更充分地被利用. |

Abstract: |
The satellite resources in spatial information virtual networks are different,and the inter-satellite links of satellite nodes change dynamically,which lead to insufficient use of network resources.The question how to maximize the usage of the space resources should be solved rapidly.In order to solve these problems,this paper provides a method to express the resources and tasks provided by the satellite networks as multidimensional vector,then we match the vector of resources and tasks by the linear programming,thus we make full use of the resourcesin the network. |
