The Simulator Networking (SIMNET) Leathrum and Stoughton 1996) simulation support environment was the 1109 Murphy and Roane first of these efforts. Its more general successors were the Distributed Interactive Simulation (DIS) DIS Steering Committee 1994) and the Aggregate Level Simulation Protocol (ALSP) Weatherly et al. 1993) simulation support environments. DIS and ALSP were designed to support separate domains within the military simulation community. DIS was designed to support the interoperability of entity level combat simulations while ....

Currently, our systems fly a varietyofNavy and Air Force missions, whichserve as the basis for our analysis of knowledge based coordination. The specific simulation environmentweareworking in is DIS [ steering committee, 1994 ] which is based on a network protocol for communication between independent, distributed simulators linked together via a network.

The underlying distributed interactive simulation (DIS) technology builds large scale simulations from a set of independent simulators linked together in a network (DIS Steering Committee 1994). It is envisioned that a synthetic battlefield will make it cheaper and safer to conduct large scale military exercises than would be possible with live field units. One of the goals of DARPA s Synthetic Theater of War 97 (STOW 97) project is to field several thousand entities during one ....

Finally, Section 8 concludes. 2 Adaptive Agent Tracking in Real world Domains The domain of our work on adaptive agent tracking is one of virtual battlefields based on Distributed Interactive Simulation environments (DIS)[7, 32]. These are synthetic, yet real world environments, and they have already been used in large scale synthetic military exercises. These environments promise to provide cost effective and realistic environments for training and rehearsal, as well as for testing new doctrine and tactics. 2 The ....

DIS was designed as a manin the loop simulation in which participants interact in a shared environment from geographically dispersed sites [28, 50] The DIS Vision document [20] described the mission of DIS as follows: The primary mission of DIS is to define an infrastructure for linking simulations of various types at multiple locations to create realistic, complex virtual worlds for the simulation of highly interactive activities.

In addition to training, CGF are also used for analytical purposes, and studies which involve large numbers of entities. 3. Network analysis According to [2], future DIS exercises will scale to 100,000 entities 2 . Numerous sources have identified the network traffic to be the main bottleneck of future distributed simulation exercises, namely because the high orders of entities all broadcast their packets onto the network. In an analysis of the 1993 ....

For example, the Department of Defense s DIS effort is trying to create large scale (100,000 users or more) simulated war games by connecting different kinds of simulators located all over the world [21]. At least three companies, Silicon Graphics, Zombie Entertainment, and Military Simulations, Inc. are working on extending the emerging DIS technology for civilian games, with an example of a DIS based game being shown at SIGGRAPH 96.

Based on the above hypothesis, we have implemented agent teams for two dynamic multi agent domains: a pilot agent teams for real world combat simulation[28, 23], and a player agent team for the RoboCup soccer simulation (proposed as a common testbed for multi agent systems) 13] The pilot agent team will be the primary focus of this article, since (i) it is the more mature among the two systems; and (ii) it operates in a real world domain, with ....
