Description

As mobile apps become more closely integrated into our everyday lives, mobile app interactions ought to be rapid and responsive. Unfortunately, even the basic primitive of launching a mobile app is sorrowfully sluggish. Mass storage devices provide to desktop and laptop computers the support to implement a virtual memory that can be viewed as an unlimited resource to be used to extend the main memory whenever needed. Unfortunately, in wireless mobile devices, like palmtops and personal digital assistants, storage memory is limited or absent due to weight, size, and power constraints, thus limiting the application of virtual memory. The limitation of resources can be addressed in a distributed environment by offloading part of the computation at runtime when lack of memory is detected. Network swapping has been an object of research in the past decade because of its application in wired networked clusters of computers. In this context, remote swapping has been found to be more efficient than local swapping when high-bandwidth network links are available. In fact, accessing the main memory of a remote server can be more efficient than accessing a local disk. However, these results are not directly applicable to wireless palmtop PCs, because of bandwidth limitations and energy constraints. The major problem in android platform is application launching time. The approach for fast application launching on the current Android system is to cache background applications in memory. This mechanism is limited by the available memory size. We propose a WS-Aging page swapping algorithm for optimize the swap memory for application launching. By using our method can speed up the application launching time more efficient.
