In-Depth Information
TASKServer used in the Tiny Application Sensor Kit. These gateways act as a proxy for the whole
sensor network to the Internet.
The server tier links sensor networks to enterprise networks where gathered data is prepro-
cessed and filtered by logging servers containing packet parsers as used in XServe (Moteworks).
The data is typically stored in SQL databases, such as TASK DBMS (TASK), PostgreSQL (Mote-
works), or mySQL. On this way, sensor readings, sensor network health statistics, sensor locations,
and calibration coefficients can be approximated and evaluated by various clients.
The client tier has access to the databases and uses graphical tools to monitor, analyze, and visualize
sensor data. It is the interface layer between the user and the deployed sensor network. Envisense, for
example, uses a graphical front-end (Figure .) similar to MoteView to visualize available infor-
mationandtocontrolthewholedeployednetwork.TASKusesTaskFieldToolsonaPDAforinsitu
