移动Ad Hoc网络下协作缓存策略研究
Research on Cooperative Caching Strategy in Mobile Ad Hoc Networks
摘要
Abstract
Caching is a common technique to improve the performance of data access. Cooperative caching,which allows the sharing and coordination of cached data among multiple nodes,can further explore the potential of the caching techniques. The basic issues of caching in mobile Ad Hoc networks are about cache placement,cache discovery and cache replacement. For this,we propose an efficient adaptive cache placement strategy based on the advantages of two basic caches and the dynamic changes of Ad Hoc networks environment. At the same time,due to the limited resources of Ad Hoc networks,the existing COOP cache discovery strategy is introduced into the core node concept,and an improved E-COOP strategy is proposed. Then,the adaptive cache placement is combined with the improved E-COOP cache discovery scheme in a caching system compared to the existing caching scheme. Simulation shows that the proposed schemes can significantly reduce the query delay,energy consumption and improve network throughput.关键词
