Simulation and emulation are techniques frequently used for performance evaluation of
wireless multi-hop networks. If the wireless devices are mobile, the movement patterns of …

Wireless communication has attracted considerable interest in the research community, and
many wireless networks are evaluated using discrete event simulators like OMNeT++ …

In this chapter, an in-depth study and comparisons of simulators and emulators have been
presented, with care accorded to their features, implementation, and use. Since emulators …

Simulators are indispensable tools to support the development and testing of cooperating
objects such as wireless sensor networks (WSN). However, it is often not possible to …

Letting users cooperate is a promising approach to improve reliability and throughput in
wireless networks, but it has not yet made the transition into practice. Unlike conventional …

Wireless network protocols are commonly evaluated through simulations. The achieved
results may vary significantly with the modeled propagation environment. Protocols that use …

Mobile users often experience communication outage and low data rate. To efficiently and
economically cope with this problem, cooperative relaying is promising. It exploits wireless …

Cellular networks are reaching their physical limits providing capacity that is almost near the
Shannon theory. However, cellular usage is still increasing exponentially with hungry …

Herrn Prof. Dr. Otthein Herzog danke ich für die Betreuung dieser Doktorarbeit sowie für die
vielen konstruktiven Gespräche und Diskussionen. Auch gilt ihm mein Dank für den nötigen …

Wireless Sensor Networks (WSNs) consist of several autonomous resource constrained
sensor nodes distributed over a geographical area. The sensor nodes can measure, for …
