Behavioral Mobility Model with Geographic Constraints

Wireless networks offer the opportunity for the users to move as they use the network in scenarios such as voice and video communication, search-and-rescue operations, etc. User mobility typically takes place in inhabited areas, hence it is subject to constraints regarding the road and building infrastructure in those areas. In this paper we propose a mobility model that takes into account such realistic topographical data. The model is driven by rules that replicate the behavior of mobile users as they proceed towards a destination. We implemented this mobility model in the QOMET wireless network emulation set of tools, and we evaluated it from several perspectives, including through a 50-node OLSR case study in an urban environment. The results demonstrate the advantages of our mobility model in terms of realism and practical applicability.
