一种节能的无线传感网异构配置模型

依据对实际传感信息分布与无线传感网络工程需求的分析,提出一种新的无线传感网异构配置模型(WSNHEDPM).对传感节点中的传感模块按需要进行组合,使其与感知物理特征量空间分布特征相适应,以减少信息冗余,降低无线传感节点的能量负担.对两种配置方法进行了配置成本、能量消耗与生存周期方面的理论和实验分析比较.理论和仿真实验表明,该模型使无线传感网在面向实际普通应用环境时更为能量有效和合理.

Energy-saving heterogeneous deployment model for wireless sensor networks

On the basis of the analysis to the practical sense information distribution and the engineering requirements of the wireless sensor network,a novel wireless sensor network heterogeneous deployment model(WSNHEDPM) is proposed.The sensor node with the necessary sense module is composed according to the distribution of the sensed physical components,thus the redundant information and the energy burden of the wireless sensor nodes are reduced.The theoretical and experimental analysis is made to compare both deployment plans in the parameters of the deployment cost,the power consumed and the survival period.The analytical and simulation results show that the WSNHEDPM is more energy efficient and more reasonable for the wireless sensor network to face the universal application area.
