Mobile active objects in Java
Mobility is a natural ability of Java objects as they can be easily serialized and transmitted between Java virtual machines, however, mobility is not provided in the standard Java programming environment. We design a metacomputing environment for Distributed, Parallel and Concurrent computing (JDPC) based on the extension to the standard Java library. JDPC supports active objects as the basic units of activity and distribution used for building applications using JDPC. This paper investigates the design, implementation and performance of mobility of active objects in JDPC. The migration is done in a scalable and secure way based-on JDPC. It has the ability to easily migrate computation, especially in heterogeneous environments. Moreover, it can be used for dynamic load balancing and dynamic deployment purposes to gain improved performance and flexibility of distributed applications.
