Abstract: The High Level Architecture (HLA) constitutes a modern approach to the distributed simulation of complex systems. With HLA, computer simulations are able to publish information between one another and synchronize actions without the need for similar computing platforms. Communication between the simulations is regulated by a Run-time Infrastructure (RTI). In this project, the RTI software Portico was studied for data exchange between federates, a member of a federation modelling a single entity, representing one platform or an aggregate simulation. Objects and Interactions are methods for data exchange; to send data from one federate to another. The main task of this project is to investigate the time required for Portico to send objects and interactions with varying number of attributes and parameters. It is achieved by measuring the duration for a publishing federate to send a message till the subscribing federate receives the messages. This report presents the benchmark design, test approach, results collected and data analysis from the evaluation of the two methods used for sending messages. Through the experiments, it was discovered the objects have better performance over interactions in terms of the duration for the receiving federate to receive all messages and also the total duration; starting from the moment the first message is sent from the sending federate until the subscribing federate receives all the messages. With reference to the Electric Vehicle (EV) application, sending messages as objects are recommended for better performance. Backed by observations from the data collected, sending messages as objects reported higher performance over interactions.
