This work introduces a dynamic model for the fire emergency evacuation problem. The model extends the concept safety introduced by Barnes et.al. for the situation when the navigation graph is dynamic. The two possible scenarios are described for using the dynamic model with a Wireless Sensor Network for fire emergency evacuation.
AIS (Automatic Identification System), a new type of radio navaid system at sea, has more and more been used on a ship to identify a target and improve the navigation safety at sea. AIS network has also been constructed at the main harbor in many countries to enhance the traffic safety and the management at the harbor. In the paper, AIS system was briefly described. It was studied on AIS network frame...
Mobile location estimation has attracted a significant amount of attention in recent years. The network-based location estimation schemes have been widely adopted based on the radio signals between the mobile device and the base stations. The two-step Least-Squares (LS) method has been studied in related research to provide efficient location estimation of the mobile devices. However, the algorithm...
Traffic congestion on major roadways costs our nation billions of dollars in lost earnings, wasted fuel consumption, injury and loss of human life. Providing motorists with real time roadway conditions is essential to mitigating traffic congestion. We propose a novel real-time messaging system that can be used to communicate imminent traffic conditions to motorists. Having such information can allow...
