A cache management object oriented simulation for mobile environments
Stylianos Drakatos, Christos Douligeris · 2007
Cache management in a real world mobile user system is too complex to allow for an analytical evaluation through a realistic mobility model. The recently proposed location-dependent applications request the design of simulation and the development of internet benchmarks. This paper presents the design of a random walk simulator that captures the movement of mobile users in Personal Communications Services (PCS) networks. A novel mathematical model is used and the validity of the data fetched from the server to identify a reduced subset of neighboring cells used to simulate the data caching computing paradigm for mobile computing. We demonstrate the capabilities of the simulator by simulating three key cache management replacement policies and measure the cache hit ratio performance.
