Human mobility has been shown to be of significant impact on the performance of Opportunistic Networks (OppNets). As shown in earlier work, the integration of geographic restrictions is not only a further step to more credibility of OppNet simulative performance evaluation, but also influences relevant metrics, such as contact duration and number of contacts. In this paper, we discuss and propose...
Although a realistic simulation of wireless networks mainly depends on a proper model of radio wave propagation, it is common to simply assume a fixed, circular range of communication. It has been shown that mobility models affect the results of the performance evaluation of wireless networks, e.g., contact and inter-contact times for opportunistic networks. However, even when using more realistic...
Realistic and scenario-dependent mobility modeling is crucial for the reliable performance evaluation of multi-hop networks. In the last decade, a significant number of synthetic mobility models have been proposed. However, only a few of these models have been validated by realistic movement traces. In the last few years, several of such traces have been collected, analyzed, and made available to...
This paper provides a model that realistically represents the movements in a disaster area scenario. The model is based on an analysis of tactical issues of civil protection. This analysis provides characteristics influencing network performance in public safety communication networks like heterogeneous area-based movement, obstacles, and joining/leaving of nodes. As these characteristics cannot be...
