The first tier is responsible for sensor data sampling and sensor data transfer to
the base station. The second tier includes software for communication to sensor
nodes and data transfer to server. The third one is deployed on the server and has
two important services, the database management and the graphical data
representation.

12.3 ProSense Common Gateway

Starting as an effort to integrate all Personal Body Area Networks with purpose of
personal health care, the Prosense Common Gateway (PCG) has become a middle-
ware software component with aim to offer an infrastructure for integrating various
wireless sensor networks to one global sensor network. The main idea is to create
a layer between user applications and various wireless sensor networks, and to
enable to those applications access to sensor data deployed everywhere.
It is planned that PCG should sit at desktop computer which is connected with
various WSN or with other devices which are connected directly with WSN. PCG
provides users a common interface for searching and gathering data from that uni-
fied sensor data space. Basically, PCG supports recommendations from OCG SWE
working group, but it is not compliant completely. Users are able to search for a
sensor data using temporal, spatial, or any value-dependant filters.
The PCG has several software components (Fig. 12.6 ):
