Abstract: Based on space heterogeneous network set up by GEO,MEO,LEO satellites,considering the heterogeneity,self-organization,self-healing and cooperated abilities of the characteristic of ubiquitous network,this paper proposed the definition of integrated space-ground TT&C and communication network,built a multi-layer satellite network based on “backbone and access” models,and studied a routing technology when satellite network was divided.Finally,network performance was analyzed and simulated in the condition of different number of failed nodes under CGR,random and flood routing algorithms.It was verified that the network can be more self-healing and survivable when CGR routing algorithm is used.

Key words: Integrated space-ground TT&C and communication network, Constraint network, Contact graph, DTN protocol systems, CGR protocol
