Investigation of cache coherence strategies in a mobile client/server environment

Abstract

In this article, we present an investigation case study based on an implementation and performance analysis of three different cache coherence strategies over a real wireless environment. Our research work considers the broadcasting timestamp, the cache coherency schema with incremental update propagation and the amnesic terminals strategies. These strategies are based on periodic broadcast of invalidation reports. The performance of these strategies is analysed through an ordinary real environment. In this environment we compare the impact of invalidation report size, broadcast interval and cache size in mobile devices. © Springer-Verlag Berlin Heidelberg 2005.
