Embodiment Construction

[0031] The satellite network protocol simulation system and method proposed by the invention are based on STK and OPNET modeler. STK is used to model satellite networks and export network scene data. Then use XML to describe the scene data, import it into OPNET modeler through OPNET's EMA library, and then model and simulate the specified satellite network protocol in OPNET.

[0032] STK (Satellite Tool Kit) is a satellite simulation design toolkit produced by AGI in the United States. It is currently a leading satellite analysis and visualization tool in the aerospace industry. It is used to analyze complex land, ocean, aviation and aerospace tasks and determine the best solution. STK supports the entire life cycle of satellite design, including conceptual design, requirements definition, design, manufacture, test, launch, operation and application.

[0033] OPNET Modeler (OPNET for short) is a network simulation software produced by OPNET. OPNET was originally used to stud...

Abstract

The invention provides a simulation system and method of satellite network protocol based on STK and OPNE T modeler construction and implementation. The said simulation system comprises a constellation module, a network module, an alignment module, a route module, a data package generator and a result evaluating module. The constellation modeling is performed by STK and the result of STK simulation is described and guided by EMA of OPNET and then the network module is generated. Using the protocol simulation function of OPNET, the alignment module and the route module are established, and then the simulation protocol is performed, finally the performance analysis is performed through the result evaluating module. The invention provides a simple and general simulation system and method of satellite network for supporting protocol simulation of all kinds of communication modes and all layers of the satellite constellation network.

Description

technical field [0001] The invention relates to the field of computer simulation, in particular to a satellite network protocol simulation system and method. Background technique [0002] Constellation networks can provide global coverage and diverse services, making them an integral part of the Next Generation Internet (NGI). Satellite networks can also provide broadband access to users in sparsely populated areas. The main challenge that the satellite network is currently facing is to design a suitable network protocol, and simulation evaluation is essential in the design process. [0003] When constructing the protocol simulation platform, the characteristics of the satellite network must be considered: 1. The satellite moves around the earth at a high speed. This high-speed mobility makes the network topology change rapidly and regularly, and the protocols at the network layer and routing layer must deal with complex processing situations. 2. The processing power and ...
