Efficient Support for Mobile Computations on the Internet

This paper discusses the necessary framework for efficient and secure support for mobile computations that can commence execution at one site, move to a dif- ferent site, and continue execution from the point where they left off. We also discuss the design and imple- mentation of a Mobile Computation System (MCS) that includes an object oriented Mobile Computation Lan- guage (MCL). Portability of computations is ensured through a Mobile Computation Manager (MCM) and a RISC-based virtual machine (RVM). Since the MCL, the MCM and the RVM are all specifically designed and implemented for mobile computations, the system can efficiently deal with the requirements and effects of mo- bility on a heterogeneous network, like the Internet.
