+%% Introduction
+\section{Introduction}
+\todo{asdf}

+
+Following the vision of the ``Internet of Things'', the amount of wireless
+devices is steadily increasing, which not only improves our standard of living
+in an age where information is expected to be available at one's fingertips, but
+also poses challenges. New devices need to be integrated into existing network
+setups, but when considering sensor nodes with very limited input capabilities,
+manual configuration can be a cumbersome process -- such devices must be readily
+usable out of the box, and should interoperate with existing infrastructure.
+Moreover, users need to communicate with their devices, they need to know which
+devices exist and use the information they collect, while too much or
+unstructured information leads to information overflow, effectively discouraging
+the user from using the network. 
+
+This paper gives an overview of the ``Chatty Things'' approach as presented by
+Klauck and Kirsche~\cite{klauck-kirsche-chattythings}, which proposes solutions
+for information filtering, auto-configuration of devices and service discovery,
+while using standard chat clients for human-to-machine communication.
+Section~\ref{sec:prereq} shortly introduces the used techniques,
+Section~\ref{sec:arch} describes the proposed system architecture for Chatty
+Things, and Section~\ref{sec:discussion} discusses possible future enhancements
+and compares Chatty Things to similar approaches.
