An Efficient Cache Replacement Strategy in Mobile Cooperative Caching

Abstract

Cooperative caching strategies have been proposed to improve access latency, reduce battery power consumption and bandwidth usage in mobile environment. However the biggest disadvantage of these mechanisms is how to manage mobile client's cache effectively due to its limited storage space. In this paper we will present an efficient cache replacement strategy in mobile cooperative caching when mobile client's cache has not enough space to store new data items. We evaluate and demonstrate experimental results on datasets by using NS2 simulator. We also prove the effectiveness by comparing it with other existing approaches. The experimental results present our proposed strategy is more effective than other approaches.
