Performance of a Simple Cooperative Individual Situation Assessment (CISA) with Respect to Information Sharing Strategy Metrics

When situation assessment is performed individually by cooperative, friendly agents working toward a commonly held goal, optimal strategies for sharing information are needed. The best strategies are often domain dependant with respect to constraints imposed by the domain itself. Appropriate strategies for information sharing can be selected by looking at the overall performance of a strategy based on a set of predefined metrics measuring qualities such as information consistency across the agents, information completeness among the agents, and timeliness of information availability to each agent. We have developed a prototype system, SAM-ISS, within a Theater Missile Defense scenario that we have used to investigate the utility of a set of metrics for determining the quality of three different information sharing strategies (ISS).
