A friend and I have been working on Java Agent DEvelopment Framework (JADE) for a while now. The idea is to enhance security mechanisms in the open source agent-deployment platform. The first step we decided to address was the actual mobility of an agent from one platform (in the sense of a dedicated machine running the JADE middleware) to another one. Turned out that it was much harder than one would imagine — especially given the fact that these agents are supposed to be mobile. Anyway, after around two months of part-time efforts, we got the agent working. Since the whole ordeal involved a lot of missing documentation and bad support, I decided to document the process through this tutorial. So, here it is. Read on to see how you can create an agent on one platform, migrate it to another platform, have it do some computation there and come back to the source.
