摘要/Abstract

摘要： 为了提高无线传感器网络的数据存储以及查询效率,同时尽可能地减少网络的能量消耗,延长网络正常工作的生命周期,提出一种基于虚拟环的节能数据存储与查询机制。该机制将传感器网络域划分成许多虚拟的环形网络,再通过基于最小网络能量消耗量的价值成本函数来定义集合环,通过集合环来执行事件数据的存储及查询任务。仿真结果表明,相比SDS方案以及其他节能的数据存储方案,该方案在延长网络的生命周期、提高能量利用效率上均获得了更好的效果。

Abstract: In order to improve the efficiency of data storage and query in wireless sensor networks,minimize the energy consumption of the network and extend the life cycle of a network to work simultaneously,an energy-efficient wireless sensor network data storage and query mechanism based on the virtual ring was proposed.Sensor network domain will be divided into many virtual ring network,then the collection ring is defined by a function of the value of the cost based on minimum network energy consumption,and the storage and query tasks of event data are executed through collection ring.The simulation results show that compared with other energy-saving programs and data storage solutions,the proposed SDS obtains better results in the extension of the network life cycle and the improvement of energy efficiency.
