Mobile ad hoc network for a heavy gas cloud boundary estimation and tracking

Mobile wireless ad hoc network (MANET) can significantly enhance the capability to monitor contaminated areas, detect pollution and gas clouds, tackle emergency incidents and support rescue teams that are working in the emergency areas. In this paper, we investigate the problem of estimation of boundary of discovered heavy gas cloud and tracking this clouds. The MANET comprised of mobile sensing devices is used to solve this task. We describe a three-phase strategy for construction a sensing system, in which mobile sensors explore the region of interest to detect the gas cloud, create preliminarily network topology and finally, adapt this topology to detect the cloud boundary and track the moving cloud maintaining the permanent communication with the central operator of the system. We evaluate the performance of the proposed strategy based on the results of simulations.
