A Review of Data Caching Techniques for Mobile Ad Hoc Networks

Data caching is a technique used in mobile ad hoc networks to improve data accessibility. The ad hoc networks are multi hop networks without a central base station and are resource constrained in terms of channel bandwidth and battery power. By data caching the communication cost can be reduced in terms of bandwidth as well as battery energy. As the network node has limited memory the problem of cache placement is a vital issue. This paper attempts to study the existing data caching techniques and their suitability in mobile ad hoc networks.
