\subsection{Mobile Ad-hoc Networks}

* Definition of MANETs
* Mention GSM, UMTS, Bluetooth, Wireless LAN, and others.

General problems in ad-hoc networks

* High level problems (differences to the Internet
  - Mobility inside the network
    * Sender/Receiver moves
    * Intermediate nodes move
  - Mobility outside the network (entering/leaving, switching on/off)
* Problems of concurrent communication
  - Multiple Access / Collisions
  - Hidden/Exposed Terminal Problems
* Problems of the wireless communication channel
  - Attenuation 
  - Fading
  - Shadowing
  - Reflection, 
  - Scattering
  - Diffraction
* Others
  - Cooperation \& Fairness

\subsection{Routing protocols}

Forwarding packets from source to sink can be a difficult task in a mobile
ad-hoc network

According to \cite{Mauve2001f}, routing in MANETs can be divided into two
major approaches: position-based routing and topology-based routing.

\TODO{Explain topology-based routing in general}
\TODO{Explain position-based routing in general}




Routing in MANETs can be divided into three different approaches:
Proactive, reactive and hybrid routing.

\section{Architectures}

Communication architectures define how data is distributed between clients in the network. Basically, two major architectures exist: Client-Server and Peer-To-Peer. 

\subsection{Client-Server}
\subsection{Peer-to-Peer}
\begin{itemize}
\item Unstrukturierte P2P-Systeme 
\item Hierarchische P2P-Systeme 
\item Strukturierte P2P-Systeme 
\end{itemize}

\subsection{Multi-Server Something}

There are many other architectures for special purposes.  

\section{Zone Server Architecture}
\subsection{Synchronisation Mechanisms}
\subsection{Evaluation criterias}
How many servers do we need? (Refer to applications, scenarios from chapter \ref{chapter-applications})
\section{Evaluation}

* Describe what a standard MANET can deliver (in the previous chapter we described what an application expects from a network)
