An adaptable framework for interoperating between wireless sensor networks and external applications

Abstract:

Wireless Sensor Networks (WSNs) are considered the bridge to connect physical and digital worlds and thus an important element of the Future Internet. Consequently, integrating WSNs with external applications is an undeniable requirement. A gateway-based solution in which the sensed data and functions of WSNs are exposed as web services is a common approach. The problem of current integration solutions for WSNs is their adaptability, i.e., the ability to reuse gateways and proxies in a multitude of sensor networks with different types of applications and data frames. In this paper, we present our proposal for this problem by proposing a framework that uses a language for describing the traffic in sensor networks named Sensor Traffic Description Language (STDL). In order to reuse the framework on a new sensor network, it is only necessary to describe the network's frame structures using STDL.
