Data-centric attribute allocation and retrieval (DCAAR) scheme for wireless sensor networks

摘要

Wireless sensor networks have enabled information gathering from a large geographical region and present unprecedented opportunities for a broad spectrum of monitoring applications. In this paper, we propose a data-centric storage scheme to determine a distribution of attributes over a large-scale sensor network such that the cost of retrieving data is minimized. We analytically determine the conditions under which the proposed architecture is beneficial and present simulation results to demonstrate the same. To the best of our knowledge, this is the first attempt to determine an allocation of attributes over a sensor network based on the correlations between attributes.
