Revision with unchanged content. The Advent of Mobile and Wireless Ad Hoc Networks arises empowered by small and powerful hardware in every-day life scenarios. Vehicular networks represent the most promising scenario for an efficient market introduction. The distribution of information in vehicular networks like safety messages requires reliable, but efficient communication and distribution of messages. This work evaluates different scenrios of wireless and mobile communications and designs transport protocols for wireless and mobile networks op ti mized for the specific network types like vehicular networks by con sidering the characteristc of these environments, comprising characteristics of the wireless transmission medium wireless LAN 802.11b. The work has been partially conducted in the Network on Wheels (NoW) project that was partially funded by the German Ministry of Education and Research. The work provides protocol proposals and guidelines for future ad hoc protocol design.
