Cache Replacement Algorithms for Coordinated Cooperative Social Wireless Networks?

Cooperative caching is a technique used in mobile ad hoc networks to improve the efficiency of information access by reducing the access latency and bandwidth usage. Cache replacement policy plays a significant role in response time reduction by selecting suitable subset of items for eviction from the cache. In this paper we have made a review of the existing cache replacement algorithms proposed for cooperative caching in a social wireless networks. We made an attempt to classify existing replacement policies for social wireless networks based on the replacement decision taken. In addition, this paper suggests some alternative techniques for cache replacement. Finally, the paper concludes with a discussion on future research directions.
