OMNeT++ and Mixim-based protocol simulator for satellite network

In this paper, we present a novel satellite network simulation platform (SNSP) based on OMNeT++ and MiXiM for researchers to develop better protocols for satellite networks. In this platform, multi-formatted satellite orbit data are permitted as input, and inter-satellite links (ISL) are created according to satellites position and specified connection rules. Correspondingly, the satellite network topology will be built dynamically. Two kinds of wireless channels that include microwave channels and laser channels are provided to simulate the signal transmission in space. A three layer fundamental satellite protocol stack is provided to utilize new satellite communication protocols as default. Meanwhile, the performance analysis of satellite communication protocol can be observed easily from the friendly graphical user interface. With modularized architecture, SNSP can be extended flexibly according to user requirements. In addition, an example is provided to illustrate how to develop protocol in our platform.
