Features

Advantages

Disadvantages

Centralized Model (Horizontal)

Ÿ Communication and coordination will be done through a central agent.

Ÿ All agents will be in the same level.

Ÿ Less reaction time

Ÿ High performance central computer and fast communication link is needed

Ÿ Very complexin both processing and communication.

Ÿ Vulnerable

Hierarchical Model (Vertical)

Ÿ Defined hierarchy will be there and agents will only communicate with neighbors.

Ÿ All agents will be in different levels.

Ÿ Simple in both processing and communication

Ÿ High reaction time

Ÿ Difficult to find the optimum solution due to unavailability of information

Hybrid Model (3D)

Ÿ Features of both centralized and hierarchical are included. Since it has both dimensions it can also be called as a 3D model.

Ÿ There will be several levels so that at least one level will be with more than two agents.

Ÿ Less reaction time

Ÿ Simple in both processing and communication

Ÿ Bit complexin both processing and communication.

Ÿ Disadvantages from both are included.
