Construction of Mobile Backbone Network(MBN)for Integrated Information Network of Space,Air and Ground

针对特殊地形或自然灾害对通信系统的影响,为提高信息传输有效性,建立基于空天地信息一体化的通信系统。针对该系统信息实时可靠传输的需求,为空天地信息一体化网络构建移动骨干网(mobile backbone network,MBN),MBN可有效简化路由,提高网络资源利用率,从而保证信息的实时可靠传输。提出了一种分布式MBN构建与维护(distributed mobile backbone network construction and maintenance,DMBNCM)算法。理论分析和仿真表明,DMBNCM算法构建的MBN是连通的,且消息和时间开销较小,对基于空天地信息一体化的通信系统有一定的应用前景。

In view of the impact of special terrain or natural disasters on the communication system,in order to improve the effectiveness of information transmission,a communication system based on the integration of space,air and ground information is established.Aiming at the requirement of real⁃time and reliable transmission of information in this system,a mobile backbone network(MBN)is constructed for the space,air and ground information integration network,which can effectively simplify the route,improve the utilization rate of network resources,so as to ensure the real⁃time and reliable transmission of information.This paper proposes a distributed mobile backbone network construction and maintenance(DMBNCM)algorithm for MBN.Theoretical analysis and simulation show that the MBN constructed by DMBNCM algorithm is connected,and the cost of message and time is small,which has a certain application prospect for the communication system based on the integration of space,air and earth information.
