Abstract—Multi agent systems provide distributed computation for decentralized software applications. Mobile agents play an important role in realizing distributed systems. Current mobile agent implementations force a tightly coupled mechanism for migration by providing a mobile agent its destination address in advance. This requirement is both restricting and inflexible. In this paper, we propose a novel agent migration scheme that eliminates destination address information from the essential components of migration. Basically, an agent migrates between platforms as a specific type of a message over a communication system that implements topic based publish/subscribe paradigm. This approach allows for loosely coupled inter-platform mobility due to the communication model, resulting in a flexible and scalable execution environment. The paper also describes a new service oriented architecture for decentralized, peer-to-peer systems an information expert ecosystem, as an application of the proposed scheme.
