Abstract—This paper proposes a dynamic geographic hash table for data-centric storage (DCS) in sensor networks. In DCS systems, data storage locations are ...
In this paper, we describe GHT, a Geographic Hash Table system for DCS on sensornets. GHT hashes keys into geographic coordi- nates, and stores a key-value pair ...
Performance evaluations show that the dynamic GHT can alleviate the resource utilization problem of DCS systems and can prolong the network lifetime ...

Abstract. Making effective use of the vast amounts of data gathered by large-scale sensor networks (sensornets) will require scalable,.
This approach entails naming the data and using communication abstractions that refer to those names rather than to node network addresses [1, 11]. Previous ...
