A memory management architecture for a mobile computing environment

In recent years, the rapid progress of hardware technology has enabled people to use mobile terminals away from the ofice or home with the use of cellular phones. However there are not a little remaining issues which are narrow bandwidth of wireless communications, the limited battery duration of mobile terminals, and others. This paper proposes a common memory management mechanism for mobile terminals and servers called Memory Management Architecture for Mobile Computing Environment (MMM). MMM allocates a part of the memory ofa mobile terminal and a part ofthe memory of a server as common memory and maintains the consistency of the common memory areas. We evaluate MMM using sample application program models against traditional memory. The result shows that MMM can reduce wireless trafic to maintain consistency, and that depending on the charge policy, a different prefetching scheme is e$cient in minimizing communication cost.
