Ring-Based Multi-Resolution Data Storage for Sensor Networks

In this paper, a ring-based multi-resolution storage scheme for sensor networks is proposed. Combined with the hierarchical scheme for data storage and query, it leverages characters of the ring-based structure to support multi-resolution data storage and query operations, achieving a good performance in terms of energy consumption. It adopts optimal parameters for ring-based storage structures, which can well handle the hierarchical data storage and query scheme with the minimized overall communication cost. Furthermore, the authors do theoretical analysis on the performance of the ring-based multi-resolution storage scheme, including energy efficiency, load balance. The experimental results indicate that significant benefits can be achieved with this ring-based multi-resolution storage scheme.
