摘要：
With the continuous development of the Internet, the scale of the data center is larger and larger, how to quickly carry out the data recovery and provide services has become a hot research topic in the disaster area. Wireless network communication system with flexible deployment characteristics and LEO satellite networks with covering a wide range are vital for disaster emergency operation and disaster recovery. In this paper, wireless networks and LEO satellite networks integrated regional disaster emergency communications and data recovery system are proposed. We design system architecture of the network and put forward a distributed data storage based on network coding. The network coding method for the distributed data storage and the data recovery principle is described in detail. The effect of network connectivity and the bandwidth demand based on network coding method is analyzed and the conclusion about network k-connectivity and data recovery for MDS (n, k). Finally the simulation analysis is done.
