Interoperability of multi-agent systems One technical challenge in multi-agent systems is associated with enabling effective communication between different AI agents and AI agent systems.28 In some cases, interactions are limited by the boundaries of native application environments, restricting the potential of AI agents to narrower and more specialized subdomains, where control is more easily retained. The interoperability of AI agents relies on common communication protocols, which are the rules and standards governing how AI agents exchange information. These protocols can generally be categorized in two types: –Predefined protocols: these are based on established agent communication languages and ontologies. Since they are predefined, the communication patterns are predictable and consistent; however, they may not adapt well to dynamic environments where new communication needs arise.29 –Emergent protocols: these allow agents to learn how to communicate effectively based on their experiences, often using reinforcement learning techniques. This enables agents to adapt their communication strategies to changing environments and tasks.30 However, decoding and understanding emergent communication remains an ongoing research challenge.31 A good understanding of the messages exchanged between AI agents is essential, otherwise it could affect the overall reliability of multi-agent systems. This inconsistency could lead to misunderstandings or misaligned actions when agents collaborate, especially in complex environments requiring precise coordination. To enhance the transparency of multi-agent interaction, the information exchanged needs to be easily accessible and interpretable by humans.
