Architecture of wireless sensor networks for environmental monitoring

There are various kinds of environmental sensor networks (ESNs) implementations for monitoring environment. These facilitate the study of environment pollution and fundamental processes of meteorology. They have evolved from passive logging systems that require manual downloading, into intelligent sensor networks that comprise a network of automatic sensor nodes and communications systems which actively communicate their data to a Sensor Network Server (SNS) where these data can be integrated with other environmental datasets. In this paper, it introduces the environment sensor networks and architecture of ESNs and then defines the Sensor Network Common Interface between the host and sensor networks as a sensor network abstraction technique and service-oriented architecture of sensor networks. Technological advances have facilitated environmental monitoring changes, it is important that environment scientists utilized ESNs.
