Wireless networks have recently gained much attraction due to several reasons: research on hardware has achieved considerable advances in the development of small and inexpensive communications devices. A fundamental property of these networks is that communication does not rely on a wired backbone. Hence, nodes additionally have to function as routers by carrying the network traffic as well as to organize and to maintain network topology. Certain aspects of routing must therefore be reviewed and new design paradigms must be found in order to face emerging challenges such as scalability and mobility.
