This paper presents a simplified form of UML state
diagrams for modeling agent mobility. Mobile agent has gained
more importance technology. The notations used to model
agent mobility are focused on capturing agent creation,
mobility paths and current agent location. In this paper, we
demonstrate how the simplification of the state UML 2.0
Activity Diagrams can be used for modeling mobile agent
applications. The paper concludes with the appropriateness
of the presented approach for modeling agent mobility with
UML state diagrams as well as with sequence diagrams of the
mobile agent system.
