In this paper we focus on the issue of application development for
wireless sensor networks (WSN). Currently, such networks are extensively
used in various business domains. However, their highly customized
operating systems and application middleware render the application
development for multiple WSNs rather cumbersome. Applications based on
multiple WSNs are typical in the emerging pervasive computing paradigm
adopted in numerous domains (e.g., telemedicine). A WSN can be
considered as a source of information similarly to a database. Motivated
by the layered driver approach introduced in the ODBC/JDBC frameworks,
we propose a middleware integration architecture. Our architecture
presents a unified and developer-friendly interface and abstract data
model towards the application. Such interface conceals the peculiarities
of the underlying WSNs as their coordination and data retrieval software
is integrated in the lower layer of the proposed middleware framework.
We present the design of the discussed architecture that is based on
open standards like XML
