Abstract: Environmental Internet of Things (EIoT) has been widely applied to environmental monitoring. The existing research of environmental monitoring based on EIoT mostly aim at specific location and specific problem without considering the management of many separate EIoT systems. With the growing number of EIoT system, how to manage these systems centrally and effectively becomes concerned focus. The problem faced by step-by-step deployment of EIoT systems is the ubiquitous heterogeneity in the sensing layer, transmission layer and application layer of EIoT. Through analyzing the characteristic of environmental monitoring and EIoT system, the meta data that can be used for EIoT system management is extracted. A unified management framework of EIoT system is proposed to manage the heterogeneous EIoT system effectively. The heterogeneity problem can be solved by detecting the abnormal data in application layer and blocking the differences in sensing layer and transmission layer among various EIoT systems.

Key words: EIoT, environmental monitoring, meta data, heterogeneity, management framework
