无线传感器网络中对等数据存储策略研究

在无线传感器网络中,除了基于基站的数据传输和管理模式以外,对等数据传输以及网内数据管理同样具有非常重要的现实意义。本文论述了传感器网络中对等数据传输的应用特点和研究挑战,以及数据存储策略与对等数据传输的关系。如何设计有效的数据存储策略是对等数据传输和网内数据管理、查询的关键技术和重要研究课题。本文分析了无线传感器网络中对等数据存储策略的分类、负载平衡和查询成功率等相关问题。本文采取基于位置的分类方法,根据策略是否依赖节点的位置信息,将节点间的对等数据存储分为基于位置的策略和无位置策略。本文综述了目前的相关研究,比较了各种策略适用的网络环境和数据查询成功率、网络负载平衡等性能指标。

Research on the P2P Data Storage Strategy in Wireless Sensor Networks

In wireless sensor networks,peer-to-peer data transmission and in-network data management is also very important except sink-based data transmission.We introduce the characteristics of the peer-to-peer data transmission applications and the relationship between data storage and data transmission.How to implement effective and efficient data storage in peer-to-peer data transmission is a key issue and big challenge for wireless sensor networks.We make a survey on peer-to-peer data storage in wireless sensor networks.Based on location,we classify the existing work into the location-based strategy and the location-free strategy.We compare the related indexes and analyze their performance on the data retrieval success ratio and load balancing.
