text: Ecosystems monitoring is essential to properly understand their development and the effects of events, both climatological and anthropological in nature. The amount of data used in these assessments is increasing at very high rates. This is due to increasing availability of sensing systems and the development of new techniques to analyze sensor data. The Enviro-Net Project encompasses several of such sensor system deployments across five countries in the Americas. These deployments use a few different ground-based sensor systems, installed at different heights monitoring the conditions in tropical dry forests over long periods of time. This paper presents our experience in deploying and maintaining these systems, retrieving and pre-processing the data, and describes the Web portal developed to help with data management, visualization and analysis.
  @cite_28: In the near future, the wireless sensor networks (WSN) consisting of hundreds or thousands of small sensor devices are expected to become increasingly popular due to their low cost and easy use. As a distributed system, they are usually deployed in unattended environments and aim to collect useful information from the sensed area. In this paper, we present a web interface model for habitat monitoring using wireless sensor network, which can be used for wide range of applications. The interface we developed provides a user-friendly environment and a set of functionalities that easies the interaction between the end-users and the WSN. Our web interface is characterized with modularity, which makes applications easily extensible.
  @cite_46: With the price of wireless sensor technologies diminishing rapidly we can expect large numbers of autonomous sensor networks being deployed in the near future. These sensor networks will typically not remain isolated but the need of interconnecting them on the network level to enable integrated data processing will arise, thus realizing the vision of a global "sensor Internet." This requires a flexible middleware layer which abstracts from the underlying, heterogeneous sensor network technologies and supports fast and simple deployment and addition of new platforms, facilitates efficient distributed query processing and combination of sensor data, provides support for sensor mobility, and enables the dynamic adaption of the system configuration during runtime with minimal (zero-programming) effort. This paper describes the global sensor networks (GSN) middleware which addresses these goals. We present GSN's conceptual model, abstractions, and architecture, and demonstrate the efficiency of the implementation through experiments with typical high-load application profiles. The GSN implementation is available from http: gsn.sourceforge.net .
summary: Middleware software for automating control of deployments is also the focus of current research efforts, in form of architectures for integrating different network deployments @cite_46 , or Web-based interfaces for interaction with and control of wireless deployments @cite_28 . Our focus, on the other hand, is on managing the data products rather than controlling the equipment from within our system.
