GeoQuorum:无线传感器网络中的负载均衡和能量有效的数据访问

GeoQuorum: Load Balancing and Energy Efficient Data Access in Wireless Sensor Networks

Jun Luo, Ying He

摘要:

在无线传感器网络(WSNs)中,当数据生产和消费严重不平衡以及数据查询的来源在空间和时间上分布时,所谓的网络内数据存储范式取代了传统的数据汇集范式。在本文中,我们首先介绍几何法定人数系统(以及它们的度量)来体现网络数据存储的思想。这些法定人数系统是“几何”的,因为曲线(而不是离散的节点集)被用来形成法定人数。然后,我们提出GeoQuorum作为一个新的法定人数系统,其中的法定人数形成曲线参数化。虽然我们的建议源于现有的工作,使用曲线来指导密集的无线传感器网络中的数据复制和检索,我们显着扩展这种设计方法,赋予GeoQuorum具有很大的灵活性,微调自己对不同的应用需求。特别是,可调性允许GeoQuorum大幅提高负载均衡性能,并在能源效率方面保持竞争力。我们的分析和模拟都证实了GeoQuorum带来的性能增强。

英文摘要:

When data productions and consumptions are heavily unbalanced and when the origins of data queries are spatially and temporally distributed, the so called in-network data storage paradigm supersedes the conventional data collection paradigm in wireless sensor networks (WSNs). In this paper, we first introduce geometric quorum systems (along with their metrics) to incarnate the idea of in-network data storage. These quorum systems are "geometric" because curves (rather than discrete node sets) are used to form quorums. We then propose GeoQuorum as a new quorum system, for which the quorum forming curves are parameterized. Though our proposal stems from the existing work on using curves to guide data replication and retrieval in dense WSNs, we significantly expand this design methodology, by endowing GeoQuorum with a great flexibility to fine-tune itself towards different application requirements. In particular, the tunability allows GeoQuorum to substantially improve the load balancing performance and to remain competitive in energy efficiency. Both our analysis and simulations confirm the performance enhancement brought by GeoQuorum.
