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)

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

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

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

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

IIP Packet Fields

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

IIP as an Overlay of IP

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
