Tittle:
Open Source Satellite Network Simulator
Summary:
A Finnish network consulting company has developed a versatile open-source tool for satellite system vendors, operators and research organisations to perform network simulations and emulations for R-Y-D purposes. The company is looking for research and technical co-operation agreements with other companies or R-Y-D institutions who are developing commercial or scientific satellite systems.
Description:
A Finnish company that provides tools -Y- services for R-Y-D in telecommunication networks has developed a satellite network simulator software tool. Simulator has been developed together with the European Space Agency to get a unified tool for the space industry in addition serving the needs of the terrestrial communication. Satellite Network Simulator is a satellite network extension to a well-known open-source network simulator Network Simulator 3 (ns-3). This platform is a discrete event simulator for networking R-Y-D. Simulator models a full interactive multi-spot beam satellite network with a geostationary satellite and transparent star (bent-pipe) payload. The reference satellite system consists of 72 spot-beams with a European coverage, 5 gateways and Ka-band frequencies.

Simulator is a dynamic system simulator, which works at a physical level burst resolution. Its use cases range from full network level performance to a single user quality of service verification. It is built to be modular and flexible to provide extensibility to different satellite communication networks and use cases.

Simulator implements DVB-RCS2 (Digital Video Broadcasting - Return Channel Satellite) and DVB-S2 specifications in return and forward link. Satellite network features include e.g.
· Adaptive Coding and Modulation (ACM)
· Return and forward link scheduling
· Demand Assignment Multiple Access (DAMA): Constant Rate Allocation (CRA), Rate-Based Dynamic Capacity (RBDC), Volume-Based Dynamic Capacity (VBDC), Free Capacity Allocation (FCA)
· Random Access (RA): Slotted ALOHA (Aloha method communication) and Contention Resolution Diversity Slotted ALOHA (CRDSA)
· Generic Stream Encapsulation (GSE)
· Return Link Encapsulation (RLE)
· Automatic Repeat reQuest (ARQ)
· Multi-beam satellite antenna gain patterns
· Packet-by-packet SNIR computation (Signal-to-interference-plus-noise ratio computation)
· Packet-by-packet co-channel and intra-beam interference tracking
· Weather traces, Land-Mobile Satellite (LMS) channel
· Error models

In addition, it benefits from numerous existing ns-3 models and features, such as various terrestrial air interfaces (LTE (Long Term Evolution), WiFi), network and transport layer models, application models, real-time emulation support and direct code execution.
Advantages and Innovations:
Simulators and emulators provide deep insight on networking building blocks in a relatively fast and cost-effective manner without a need for early-stage prototypes. Simulations and emulations may have complementary roles; e.g. simulations can be used for a full-blown network performance analysis and emulations can focus on the protocol interaction. Example use cases include e.g.

· Algorithm and protocol design, development and optimization
· Proof-of-concepts to support product development
· Full satellite system performance assessment and end user quality of service verification
· Higher layer protocol and application performance optimization
· Visual satellite network demonstrations
