ABSTRACT

MANET(Mobile Ad-hoc Network) is consisted of only mobile nodes. Every node plays a role as router which performs data transfer function because it communicates each other using multi-hop communication, It has disadvantage that data access performance gets lower by moving of nodes, multi-hop, and limited system resource. Caching scheme improves this data access performance and availability. In this study, we proposed cache scheme to improve data availability by enhancing consistency of overlapping data which nodes are saving and decreasing query delay time to search data. We compared with GC, COOP method and experienced to evaluate performance of proposed method and identified efficiency of this method.
