Executive Summary

Wireless networks have become omnipresent; there are different architectures available, e.g., GSM-driven mobile phones, or laptops equipped with 802.11 WLAN. A challenging network architectures are so-called wireless multihop networks, e.g., ad hoc, sensor, or mesh networks. In these networks, the participating nodes themselves provide the infrastructure. This lack of already available infrastructure expresses itself primarily during the start-up phase of the wireless multi-hop network, as nodes need to establish their own infrastructure before being able to communicate. For instance, upon deployment the nodes act independently, as they are unaware of each other. In this stage communication is unreliable and slow.
