2. Introduction Intelligent Mobile Agent (IMA) IIP
autonomous decision maker,
uses acquired knowledge to determine future actions.
IIP
an IP-based protocol that allows IMAs to function within the network layer.
Extension of Internet Protocol (IP)

3. IIP Motivation Compatibility with IP
Legacy Network Interoperability
IP is standardized, widely researched infrastructure, more so than current space-based networks
Ability to handle dynamics of space-based networks
Changing topology
Latency
Jitter

4. IIP Architecture: Contribution to Space-Based Networks
Flexibility
Handle multiple mission criteria (in terms of message requirements)
Framework allows migration and evolution to newer protocols and technologies
Adaptive
Handle dynamic network events
Loss of link or node
Deal with changing network requirements
Reliable Data Transfer, Bandwidth, Timing

5. State-of-the-Art Delay Tolerant Networks (DTNs)
SCPS Network Protocol (SCPS – NP)
Active Networks
Cognitive Packet Networks (CPNs)
Overlay Networks
Mobile Agents

6. Big Picture: Implementation of IIP
Extension of the Network layer of TCP/IP Protocol stack
Add ability to read and execute code at the Network layer
Application
Transport
Network
Data Link
Physical

7. IIP Packet Fields

8. IIP Packet Fields (cont’d)
Scalable, Bit-Efficient Header
Carries only necessary bit fields
Reduces transmission overhead
IP Packet
IIP Packet (low intelligence)
IIP Packet (high intelligence) A G A C F G A B C D E F G

9. IIP as an Overlay of IP

10. Future Work Development of Intelligent Agents
Start with simple AI then progress to more complex AI
Simulation of IIP using NS
Test IIP Implementation Using Space-Based Network Emulator
Refine and improve considering
Overhead
Security
