一种基于云计算的无线传感网体系结构

Architecture for wireless sensor network based on cloud computing

提出了一种基于云计算的无线传感网体系结构。整个传感网被划分为若干个分区;云作为虚拟汇聚节点,有多个汇聚触点,每个触点负责一个分区中传感器的数据收集;每个分区中的传感器组成本地传感网,所有本地传感网通过云连接成一个整体;数据在云中分布存储、并行处理。模拟实验表明,新结构传感网的数据传输性能明显提升。该结构适用于以数据为中心的无线传感网。

This paper proposed a novel architecture for WSN based on cloud computing. The whole WSN divided into several zones. A cloud acted as a virtual sink and had many sink points, each of which collected sensing data from sensors in a zone. The sensors of a zone constituted local wireless sensor networks （LWSNs）. All LWSNs integrated together through the cloud. The cloud stored collected sensing data in distributed manner and processed them in parallel way. Simulation results show that the data transmission performance of sensors in the proposed architecture improved significantly. The proposed architecture is suitable for data centric wireless sensor network.
