传感器观测服务是传感网的核心服务,用于管理和获取异构传感器的元数据和观测数据。在一定的硬件和软件条件下,评估传感器观测服务的性能有助于发挥传感网监测目标地物时的最优性能。本文以服务性能的响应时间为评估标准,提出了传感器观测服务性能的评估方法。此方法分别从不同的操作和软件配置等方面进行了响应时间的评估,分析出传感器观测服务中不同操作的性能特征,提高了传感器观测服务的设计与部署效率。
Sensor Observation Service is the core service of sensor network, which is used to manage and obtain the metadata and observation data of heterogeneous sensors. Under certain hardware and software conditions, evaluating the performance of the sensor observing service helps to maximize the performance of the sensor network in monitoring the target. In this paper, the service performance response time is taken as the evaluation standard, and the evaluation method of sensor observation service performance is proposed. This method evaluates the response time from different aspects such as operation and software configuration, analyzes the performance characteristics of different operations in the sensor observing service, and improves the design and deployment efficiency of the observer service.
