Tracking pedestrians and emergent events in disaster areas

摘要: Most of the existing research on emergency evacuation strategies focus city planning that highly depends use vehicles or from buildings. However, for large areas with limited such as theme parks, pedestrians and emergent events must be tracked safety reasons. As hazards may cause certain damages to services, networks disaster resilience are needed achieve mission-critical operations search rescue. In this paper, we develop a method tracking during disasters by opportunistic ad hoc communication. our network model, smart-phones store carry messages number mobile sinks. Mobile sinks responsible communicating reaching effectively. Since positioning has direct impact performance, propose physical force based (PF), grid allocation (GA) road (RA) approaches sink placement mobility. The proposed analyzed through extensive simulations using real park maps human mobility model scenarios. simulation results show significantly better coverage higher rescue success without producing increased communication overhead compared two random movement models.
