Mobile ad hoc networks (MANETs) are anticipated to play an important
role in the future of networking, making the performance analysis of
algorithms and protocols for MANETs an important topic.
The mobility of the nodes and the characteristics of these wireless
networks, such as a frequently changing topology, unreliable
communication links, and a limited transmission range, require the
development of algorithms and protocols performing efficiently under
such circumstances.
Measuring the performance of algorithms and protocols for MANETs is
complicated by the costs associated with conducting a real-world
experiment and the conditions of such an experiment not being easily
repeatable. Therefore, as with wired networks, network simulation is
common practice for evaluating the performance of such a system.
Traditional network simulators designed for simulating wired
networks lack the support necessary for mobile networks, like
modeling node movement and spatial constraints (e.g. propagation
obstacles). In the past, some of these network simulators have been
adapted or newly developed to also support wireless networks.
However, few of these support the modeling of spatial constraints.
Also, state-of-the-art network simulators generally have a high
resource consumption and lack user interactivity, modularity, and
adaptability. Therefore, we have developed Cubus, a network
simulator fully capable of simulating MANETs and supporting the
aforementioned additional features.
The development of the system was split across two theses: In the
first thesis, the core system was developed. The support of node
movement, modeling of spacial constraints, and user interactivity is
developed in this thesis.
