This paper proposes IIP (intelligent Internet protocol) which effectively addresses the issues involved in wireless communication at network layer such as support for mobility, frequent loss of connection clue to fading, hand-offs and security. We have chosen to use intelligent agent technology for our architecture of IIP because it provides desirable properties such as speed-up and efficiency, robustness and reliability, scalability and flexibility, development and re-usability. We make use of four intelligent agents namely principal agent (PA), agent for address resolution and mobility support (AARMS), agent for error handling and recovery (AEHR), agent for network security (ANS) and design each agent based on BDI (belief-desire-intention) architecture. A variant of blackboard architecture is used for inter-agent communication. Special care has been taken to make the proposed IP compatible with existing networks. The proposed work has been simulated and verified for its operational effectiveness.
