Enhanced cost effective cache invalidation for mobile clients in stateless server environments

초록

In [1], we proposed a cost-based cache invalidation method for mobile clients. However, our previous work did not concern a remarkable difference of data transfer rate between download and upload links. In this paper, we present an enhanced cost-effective cache validation scheme with a new cost function. We prove that our proposed scheme greatly increases the cache reusability and the uplink message overhead does not lead to serious performance degradation through experiments.
