Introduction • Intelligent Mobile Agent (IMA) – 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) Glenn Research Center at Lewis Field

IIP Motivation • Compatibility with IP – Legacy Network Interoperability – IP is standardized, widely researched infrastructure, more so than current spacebased networks • Ability to handle dynamics of space-based networks – Changing topology – Latency – Jitter Glenn Research Center at Lewis Field

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 Glenn Research Center at Lewis Field

State-of-the-Art • • • Delay Tolerant Networks (DTNs) SCPS Network Protocol (SCPS – NP) Active Networks Cognitive Packet Networks (CPNs) Overlay Networks Mobile Agents Glenn Research Center at Lewis Field

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 Glenn Research Center at Lewis Field

IIP Packet Fields Glenn Research Center at Lewis Field

IIP Packet Fields (cont’d) • Scalable, Bit-Efficient Header • Carries only necessary bit fields • Reduces transmission overhead A • IP Packet G • IIP Packet (low intelligence) A C F G D E F G • IIP Packet (high intelligence) A B C Glenn Research Center at Lewis Field

IIP as an Overlay of IP Glenn Research Center at Lewis Field

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 Glenn Research Center at Lewis Field
