The level of autt)nt)nty ill which individu:d agunts function is of critical importance to the overall operation of multiagent systems. The term h, vel of autononty refers to the type of interactions between an agent and other agents in its system. In well-defined contexts, agents can be designed fur a single level ~)t" autonomy by predicting Ihe type of(More)
Accurately describing simulation characteristics is essential for their interoperability and composability. The internal processes and results produced must be rigorously characterized and valid in the context of their application. Only if this is possible in an effective and economic manner can simulations be extensively reused, through either(More)
The level of autonomy at which individual agents function is of critical importance to the overall operation of distributed agent-based systems. An agent's level of autonomy for a goal specifies the interaction framework in which that goal is planned. Substantial performance benefits for agent-based systems may be realized by agents that are capable of(More)
In this paper, Extended Statecharts are used as a comprehensive modeling mechanism for the behavior modeling of Sensible Agents. Extended Statecharts allow for the explicit representation of declarable problem-specific agent soft failures, thereby allowing for failure related information to be incorporated within the high level system design. An example of(More)
A domain-independent approach to reasoning about the autonomy level of agent goals is presented. The approach is based on general representations of knowledge about goals and resources. A hybrid two-stage reasoning process is proposed, consisting of a belief net and a case-based reasoner. Belief nets are examined in detail as a mechanism for establishing(More)
This paper presents a case study based on a radar interference control problem using frequency assignment as the control mechanism. The results suggest that locally autonomous agents will generally not converge to an acceptable solution and a central control using a master will converge, but at a higher cost. These results drive the need for negotiation(More)
The use of object-oriented (OO) methodologies for software design has become increasingly popular in the last ten years. OO is perceived as providing many benefits, including reusability, modularity, avoidance of duplication, reliability, flexibility for expansion, and portability. To reap these benefits, careful attention must be paid to define a set of(More)
A mobile agent is an autonomous agent that is not bound to the system on which it begins execution. Unfortunately, the mobility and interaction inherent in mobile agent technology introduces significant security problems, such as malicious host attacks, which can disable the agent, alter its code, or disrupt its communication. This research explores(More)
The construction and analysis of Multiple Input Multiple Output (MIMO) subnets is discussed. It is shown that Hierarchical TimeExtended Petri Nets (H-EPNs) allow the development of structured MIMO subnets through the use of bottom-up Petri Net synthesis techniques. The paper analyzes Petri Net extensions that allow a truly hybrid approach to Petri Net based(More)
