【摘要】 在分析集中式体系结构和分布式动态体系结构基础上,提出了一种提高目标跟踪无线传感器网络使用寿命的模型,该模型是一个静态簇型架构,由异构传感器组成,传感集群中的每个成员节点采用两种运作模式:工作模式和睡眠模式。结果表明,所提出的架构比集中式系统消耗更少能源,而且使用寿命更长。更多还原

【Abstract】 Base on the anlalysis of the centralized architecture and dynamic distributed architecture,a model to improve the lifetime of target tracking wireless sensor network is proposed.The model is a static cluster-mode architecture.The model consists of heterogeneous sensors and each sensing member node in a cluster uses two operation modes—active mode and sleep mode.The performance results illustrate that the proposed architecture consumes less energy and increases lifetime than centralized and dynamic clustering architectures.更多还原
