> 中文摘要: 提出了一套基于环结构的传感器网络多分辨率数据存储机制,结合层次结构的存储查询方案,有效地利用了环结构的特性高效、节能地支持事件信息的不同分辨率的存储和查询操作,并采用优化的环结构参数,在基于环的层次结构数据存储架构中能够最小化网络节点的总体通信能耗.同时,对环结构多分辨率数据存储机制的相关性能从节能性、负载均衡性等多个角度进行了具体理论分析.模拟实验结果表明,基于环的层次结构存储机制能够高效、节能地支持传感器网络事件数据的多分辨率存储和查询操作.
Abstract: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.
