Mobile Agents : Introduction

• Mobile Agents are the pieces of codes that are used to store data and are independent in nature i.e. they are self-driven and does not require corresponding node for communication as they are capable of functioning even if user gets disconnected from the network.
• They are also called as transportable agents.
• They can be broadly classified into two types:
  1. Agents with pre-defined path.
  2. Agents with undefined path i.e. Roamer.

 

Life Cycle : Mobile Agents

The life-cycle of these agents ensures that they are :

• Able to adapt the environment i.e. either home or foreign environment.
• Able to switch among the positions of one node to other.
• Focused towards the final output.
• Autonomous.

Mobile Agents : Life Cycle

Advantages : Mobile Agents

• Autonomous-Self Driven in nature.
• They possess Less delays in network.
• They are Maintainable/Maintenance Friendly.
• They are Fault tolerant.
• They possess less load on the network.

Disadvantages : Mobile Agents

• Less secured : Security is the major loop while this concept.

 

Applications : Mobile Agents

• Mobile Computing.
• Parallel Computing.
• Distributed Computing.
• e-Commerce.
