Gossip-Based Data Fusion Framework for Radio Resource Map
Jin Song Yang · 2010
Wireless sensor networks are used as efficient technology to detect changes in environment and resources. In disaster scenarios, it is especially useful to form a global view of resource availability map based on locally sensed and measured data, which will support further decision making in system discovery and rescuing process. Each sensor node can provide the measurement and local information in its own sensing and measurement coverage, contributing as a piece of "resource map", so that the sink can generate the whole picture of "resource map" on resource availability of the entire area. The generation of radio resource map is the research focus of this paper, since in disaster scenarios with the knowledge about availability of radio frequency band, it is possible to estimation the base station location and the its damage status.
