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)

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

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
