Caching Technique for Improving Data Retrieval Performance in Mobile Ad Hoc Networks
Mobile Ad Hoc NETworks (MANETs) provide an attractive solution for networking in the situations where network infrastructure or service subscription is not available. Cooperative caching scheme can improve the accessibility of data objects. In this paper, the authors proposed a neighbor group data caching scheme called Neighbor Group Data Caching (NGDC) for improving data access efficiency in MANETs. The objective is to improve data availability and access efficiency by collaborating local resources of mobile nodes. Cache resolution and cache management are the two problems of cooperative caching. To improve data availability and access efficiency, cooperative caching discovers data sources which induce less communication cost by utilizing neighbor group nodes.
