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.
