Design Concepts of a persistent Wireless Sensor Testbed

Abstract:

In this paper we introduce our work-in-progress wireless testbed. The testbed consists of hybrid nodes. Each node contains a sensor node and a mesh router. We present concepts which exploit the features of an existing wireless mesh network for the wireless sensor network. The concepts include the \emph{wireless sensor testbed integration} (WSTI) which simplifies the management and provides a basic infrastructure for the sensor network and experiments. The integration into the Linux kernel is realized by the \emph{wireless sensor kernel interface} (WSKI). \emph{Network check points} (NCPs) enable long-term experiments that may span several weeks although they cannot be done in one continuous session.
