Mobile distributed computing system and method for storing node fault-tolerant information

The invention discloses a mobile distributed computing system and a method for storing node fault-tolerant information. The method comprises steps as follows: (1), a fault-tolerant information management module of a base station records mobility information of a mobile host in a service domain; (2), unrepeated serial numbers of nodes of the mobile host are maintained, and reference time is set; (3), fault-tolerant information of the nodes of the mobile host is synergized, collected and maintained by the base station through the fault-tolerant information management module; (4), the fault-tolerant information management module of the base station stores the collected fault-tolerant information of the nodes in a network sharing and storage device through a high-speed wired network, so that the fault-tolerant information of the nodes of the mobile host are stored and shared. The mobile distributed computing system and method can reduce wireless signal interference produced when the nodes of the mobile host transmit calculation process check points to the local base station, effectively supports a check point rollback recovery mechanism in the mobile distributed computing system and better meets the requirement of the mobile distributed computing system for reliability in various fields.
