3. 3 Introduction The definition of agents Agents are the autonomous programs situated within an environment (either a host or a network), which sense the environment and acts upon it to achieve their goals. The special properties of agents: mandatory and orthogonal (optional) properties

4. 4 Introduction Mandatory properties: Autonomy: agents operate without the direct intervention of humans or others, and have some kind of control over their actions and internal state; Decision making: reactive or proactive decision making; Temporal continuity: agents are continuously running processes; Goal oriented: an agent is capable of handling a task to meet its desired goal;

5. 5 Introduction orthogonal properties : Mobility: agents are capable of roaming around in an electronic network; Communicative: agents interact with other agents and humans; Collaborative: an agent should be capable of computing the desired tasks by cooperating with other agents; Learning: agents can learn the environment factors, user preferences, etc. and develop certain degree of reasoning to take intelligent decisions/actions.

6. 6 Agent technology

7. 7 Agent technology may be classified as single- agent and multi-agent systems In single-agent systems, an agent performs task, while performing a task, an agent may communicate with a user or remote system resources The agents in MAS may cooperate with each other to achieve their individual goals, and also may interact with users and system resources.

8. 8 Agent technology Multi-agent systems(MAS) Static agents based MAS: Mobile agent based MAS: The agents migrate from one machine to another to complete its task.
