Abstract

This paper reports on extending the Jade agent toolkit with a new mobility service. Jade implements a straightforward mobility model that is based on a pull migration strategy. This strategy is a good choice in specific environments, because only necessary classes are loaded. However, loading classes might cause a network overhead in other scenarios, in particular wide-area networks. In addition, Jade's code cache cannot distinguish between different versions of the same class, which is a drawback in long-running agent systems. We have implemented a new mobility model, named Kalong, and integrated it as a new mobility service in Jade. The paper also reports on first experiments comparing the migration performance of Jade's and Kalong's mobility service.
