Cache Policies for Smartphone in Flexible Learning: A Comparative Study

Abstract

The rapid evolution of technology has changed the face of education especially usage of mobile device that aren't devoid of any student hand. The term “mobile devices” covers many different kinds of devices (e.g. smart phones, cell phones, personal digital assistant (PDA), tablets, netbooks, etc.). Hoping take advantages of these devices in mobile learning which allow learning anywhere and anytime. There may be some obstacles to use these devices, such as wireless bandwidth and client’s battery power Data caching is an appropriate technique for reducing wireless data transmissions in mobile information systems. In this paper we present overview of most popular cache techniques which use performance metrics that might be adopted to assess the quality of caching policy.
