一种异构配置的无线传感网成本分析

One Heterogeneous Deployment Model for Wireless Sensor Network and Its Cost Analysis

根据对无线传感节点组成与无线传感网应用环境中各物理特征量非均匀分布,且在分布密度上具有较大差异的情况分析,提出一种异构分布配置模型,在网络配置时采用与感知物理特征量空间分布特征相适应的异构节点配置方法。由此减少节点配置冗余和信息冗余,降低无线传感网的配置成本。仿真实验证明,该模型可节省成本,是更适合于未来无线传感网实际应用要求的通用结构配置模型。

Based on the analysis to the constitution of the wireless sensor node and the analysis to the conditions that each physical component is distributed unevenly and there is normally immense distribution difference existing between these physical components, a novel Wireless Sensor Network Heterogeneous DePloyment Model （WSNHEDPM） is proposed for the future wireless sensor network deployment. In this deployment model, the wireless sensor node is deployed with the distribution comply with the distribution of the sensed physical components to cut off the deployment redundancy and information redundancy so to save the deployment cost. And the further analysis to the deploy cost of the model is made. The analytical and simulation results show that the WSNHEDPM can save deploy cost and more suitable for the future requirements to the Wireless Sensor Network.
