Introduction

• Inter-agents group communication and coordination
• Construction and maintenance of multicast tree
  are required issues.

Three main areas in terms of overlay construction
for data distribution in various application
level multicast approaches

• Mesh-First approaches
• Tree-First approaches
• Implicit approaches
• NICE designed for large groups and low bandwidth,
  real-time application.
• CAN which uses a virtual addressing approach.

Mesh-First Approaches (cont.)
Internet Network
- Example protocols Narada, ALMI,
Scattercastetc. - Supporting of many-to-many
multicast for real-time application such as
audio/video conferencing applications with
small-sized group.
7
Tree-First Approaches
Internet Network
request to join group
- Example protocols Overcast, TAG, Peercastetc.
- This approach has the advantage of being
scalable

Future works

• Implementation add on P2P-based mobile agent
  platform to accomplish the goal of inter-agent
  communication and coordination.
