Performance analysis of the Advanced Amphibious Assault Vehicle Personnel variant (AAAV-P) Vetronics Communications System high speed data bus

Abstract

The United States Marine Corps Advanced Amphibious Assault Vehicle Personnel Variant (AAAV-P) is a critical weapon system that supports the Naval Operational Maneuver from the Sea (OMFTS) concept. The AAAV-P will provide the Marine Corps with the ability to project naval power ashore in support of strategic objectives. The Marine Corps is relying on the AAAV-P to exploit the sea and land terrain in order to attain surprise and be able to rapidly take advantage of weak points in enemy littoral defenses. The first prototype of the AAAV-P will be completed in June 1999. Successful operation of the AAAV-P is heavily dependent upon the Vetronics System communications network residing within the vehicle. The Vetronics System supports three networks: a High Speed Data Bus, a Utility Bus, and a Powertrain Bus. This thesis develops a model of the High Speed Data Bus, which is considered the main data bus within the AAAV- P. The simulation results of the model are analyzed to determine if the High Speed Data Bus is properly designed to handle the anticipated communications traffic that will traverse the network. The network performance capability is evaluated under various scenarios.
