COOPERATIVE CACHE MANAGEMENT PERFORMANCES WITHIN MANETS

Mobile Ad hoc Network are autonomously structured multi-hop wireless links in peer to peer fashion without aid of any infrastructure network. Due to lack of infrastructure support, each node in network act as router, coordinating to forward data packets to other nodes. Caching of frequently accessed data in ad hoc networks is a potential technique that can improve the data access, performance and availability. A cooperative cache-based data access framework lets mobile node cache the data or the path to the data to reduce query delays and improve data accessibility. Due to mobility and resource constraints of ad hoc networks, cooperative caching techniques designed for wired network may not be applicable to ad hoc networks. The objective of cooperative caching is to improve data availability and access efficiency by collaborating local resources of mobile devices. This paper reviews the various cooperative cache management techniques in the mobile ad-hoc networks.
