Abstract

This paper presents pocket caching, a prefetching cache strategy to identify the data to be loaded in a mobile node participating in a mobile cloud computing (MCC) environment. MCC is a new paradigm and is consider as the extension of mobile devices services in an elastic and transparent way through the ubiquitous wireless access to third-party computing and storage resources. New applications are emerging in this context. They are mainly characterized by large amount content generation in a collaborative and dynamic way. Additionally, the user interaction (content access and generation), depends on user location and interaction of others users. User interaction may be affected by network problems in some points of interest. This motivate pocket caching proposal. Pocket caching to reduce data availability issues in points of interest, designs a multi-objective optimization strategy to include characteristics of MCC environment and some application behaviors. This proposal was validated using both the SPEA2 algorithm execution performance and the quality of the results. The preliminary results show good behavior.
