Cooperative Cache Replacement Policy for MANETs

Mobile Adhoc Networks (MANETs) are autonomously structured multi-hop wireless links in peer to peer fashion without aid of any infrastructure network. In MANETs network topology is dynamic, as nodes are mobile. Due to this dynamic topology and multi-hop environment data availability in MANETs is low. Caching of frequently accessed data in ad hoc networks is a potential technique that can improve the data access, performance and availability. While caching the new data items, it is very important which data item is to be removed, as in MANETs the data is not stored only on behalf of caching node but interest of the vicinity is also considered. In this paper the authors presented a new cache replacement policy for MANETs. This policy is based on multi-parameter value called SAT. We simulate the proposed work on OMNET++ and the simulation results shows that proposed replacement policy helps to improve the data availability in network.
