What is MOSES
The Military Open Simulator Enterprise Strategy is an exploratory effort designed to evaluate the ability of the Open Simulator to provide independent and secured access to a virtual world.
Year One Goals:1. Provide a completely independent virtual world capability. Runs in an enclaved
network, capable of multiple levels of secured processing.2. Provide a stable in-kind Second Life®-like environment.3. Provide guidance to other organizations wishing to replicate the MOSES results.4. Link with other organization in a hyper-grid manner to demonstrate external
growth and scalability.
Next Steps:5. Secured/Encrypted Communications6. User Authentication with certificates and CAC7. Larger Scale User Support8. Integration/Conformance with the DoD Virtual World Framework

What value does MOSES bring to military training applications?
Breaks the traditional paradigm of modeling and simulation.
• Art Pipeline• Computationally Steerable
– The scripting language can enact changes to objects without restarting simulation.• Out of the Box External Communications Mechanisms
– Everything in the environment is an interactive object, capable of being driven by external behavior models.
• Every Object can connect to an external data source.• Flexible Terrain
– Real world terrain sources can be used.– Terrain is deformable while simulation is running; May be restored via scripting
• Persistent Virtual Environment– Capable of High Availability and Uptimes
• Multiple Communications Options– Point to point chat, point to many chat– Point to point VOIP, point to many VOIP – can replicate military radio behavior

What are the down sides?
• Insecure communications between client and server. – Phase II of the MOSES project will look at 100% encryption of all data
transmitted/received.• Content is produced to the client “on demand”.
– Susceptible to network lag.• Physics engine needs work.
– Phase II of the MOSES project will experiment with alternate physics engines.

Lessons Learned
• Created preconfigured client.– Subject matter experts may not be technical.
• Network is most precious resource.• Community is critical for sustainment.
– Regular office hours– Assistance with management
• Adopt flexible culture– Plan ahead for growth, network/computing hardware– Listen to open source developers to help make informed decisions
