ABSTRACT
First responders show specific movement and traffic patterns that are closely related to their current task during a disaster relief mission. In order to develop efficient communication systems both aspects should be considered. This is important especially if Delay Tolerant Networks (DTN) are used, because they are exploiting the mobility of the nodes in order to deliver messages in scenarios with intermittent connectivity. In a disaster scenario, such a network is formed by the communication equipment of first responders.
In this paper, we evaluate different mobility models and traffic generation options and show their impact on the performance of the epidemic routing protocol. Our results show that the correlation between traffic and mobility in disaster scenarios has a significant impact on the delivery ratio and experienced delay, respectively

Poster: Utilization of Additional Nodes in Hybrid DTN-MANET Scenarios
CHANTS '17: Proceedings of the 12th Workshop on Challenged NetworksIn case of disasters, efficient and robust communication is essential. Hybrid network architectures combining traditional mobile ad hoc networks (MANETs) and delay tolerant networks (DTNs) have been proposed to achieve both aspects. The combination is ...
Mobility entropy and message routing in community-structured delay tolerant networks
AINTEC '08: Proceedings of the 4th Asian Conference on Internet EngineeringMany message routing schemes have been proposed in the context of delay tolerant networks (DTN) and intermittently connected mobile networks (ICMN). Those routing schemes are tested on specific environments that involve particular mobility complexity ...
Evolutionary deployment and local search-based movements of 0th responders in disaster scenarios
AbstractThe establishment of communications in disaster scenarios is of paramount importance, especially because preexisting communication infrastructure is likely to be destroyed or malfunctioning. Consequently, there is a need for an ...
