PerLa:A Language and Middleware Architecture for Data Management
and Integration
ABSTRACT
A declarative SQL-like language and a middleware
infrastructure are presented for collecting data from
different nodes of a pervasive system. Data management
is performed by hiding the complexity due to the large
underlying heterogeneity of devices, which can span
from passive RFID(s) to ad hoc sensor boards to
portable computers. An important feature of the
presented middleware is to make the integration of new
device types in the system easy through the use of device
self-description. Two case studies are described for
PerLa usage, and a survey is made for comparing our
approach with other projects in the area.
