An Approach for Interworking Heterogeneous Networks with DTN and IP Routing in Space Internet

Abstract

In a space mission, there are various types of nodes which can adopt individual communication protocols for aircraft on Delay Tolerant Network (DTN) and terrestrial control center on TCP/IP. For efficient routing between heterogeneous networks, we propose an approach for interworking heterogeneous networks with DTN and IP routing in space Internet. We design it by configuring Interplanetary Overlay Network (ION), based on IP forwarding rule and gateway. Also, we design scenarios to evaluate its performance. The experimental results verify the proposed protocol is suitable for interworking heterogeneous networks in space Internet.
