| Abstract | A distributed wireless sensor network to guide navigation of the users in emergency situations such as forest fire, sleet and chemical leak detection. The main aspect of the proposed system is to identify the dangerous regions and plan a path for each user to one or more pre-known exits on the field that lead to safe departure. The sensor network assisted navigation is designed based on a Road Map (RM) approach without relying on the location information. The road map consists of static sensor nodes connected through dynamic path. Without any pre-knowledge of the route, the users tend to move towards destination even in presence of obstacles by communicating with the sensors. The RM approach is able to cope with the dynamics of the dangerous area. Addressing node failures and traffic redirection mechanism is also adopted to give congestion free shortest path. The simulation results of the proposed road map approach shows that it achieves comparable performance with significantly reduced communication overhead and guaranteed safe navigation for all internal users. |
