Movement patterns for mobile networks in disaster scenarios

Node mobility is one essential feature of mobile networks, especially for delay tolerant networks, where packet delivery is only possible through node movements. In mobile ad hoc networks, mobility adds new challenges to the protocol design. Therefore, realistic movement models are required to evaluate protocol performance. Usually, random node movement is considered for that but this kind of movement is not applicable for first responders in disaster scenarios. Their movements are driven by tactical mission requirements and highly depend on the type of disaster. In this paper, we analyze two different movement scenarios to derive common features as well as differences and present how to use these results to generate generic and at the same time realistic movements for first responders.
