To Do or Not to Do: Metadata-guided Query Evaluation in Content Caching Networks

Free registration required

Executive Summary

To support emerging pervasive computer applications, efficient data access and information sharing is essential in mobile wireless environments. The data-centric storage approach provides energy-efficient data dissemination and organization. However, wireless devices have limited storage and are energy constrained. To address these issues, the authors introduce the concept of content caching networks, in which the collected data will be stored by its content in a distributed manner, while the data in the network is cached for a certain period of time before it is sent to a centralized storage space for backup.
