The advantage of virtual networks is to test routing-algorithms or distributed software in an easy-to-use, cheap and well-arranged way. Optimized Link State Routing (OLSR) and Babel are two modern routing-algorithms for mobile ad-hoc networks that distinguish faulty links from good link connections in their routing process. Typically virtual networks provide nearly perfect link connections without any network traffic disruptions. The Traffic Control (tc) tool is able to manipulate connections in terms of delay and packet loss.
In this bachelor thesis virtual network scenarios are created with VNUML and Qemu and manipulated with tc in order to analyze the behavior of ad-hoc routing algorithms like Babel and OLSR. The behavior of well-known TCP congestion control algorithms, e.g., TCP Vegas and TCP Reno are analyzed, too.
