Caching Strategies Based on Information Density Estimation in Wireless Ad Hoc Networks
The authors address cooperative caching in wireless networks, where the nodes may be mobile and exchange information in a peer-to-peer fashion. They consider both cases of nodes with large- and small-sized caches. For large-sized caches, they devise a strategy where nodes, independent of each other, decide whether to cache some content and for how long. In the case of small-sized caches, they aim to design a content replacement strategy that allows nodes to successfully store newly received information while maintaining the good performance of the content distribution system.
