Research previously conducted that is similar to this research includes OSOITE projected conducted by Y. Tobe, .et al. as the JST (an independent administrative agency of the Japan Science and Technology Agency) CREST “Advanced Integrated Sensing Technologies” project . Among the research previously conducted, “Tomu” has proposed novel technologies, such as: “TomuDB” that disperses and manages two or more relational DBs storing large-scale temporal-spatial sensor data; the algorithm STAX that performs high speed similarity searching; and the sensor interface description language USML for easily incorporating new sensors into a system. The research for this application is similar to Tomu in that in response to a demand it queries the dispersed resources by using an overlay-network and obtains the desired data. However, it is not necessary for the collected data to be processed according to its application at the terminal, because the router itself performs the data mashup simultaneously with data transfer. With this functionality, changes after introduction can be simply made by system operation. Moreover, since the main purpose of the sensor interface description by USML is to convert data formats, it lacks a “function to actively and dynamically customize the role of each sensor node as need arises;” something that will be achieved by this application research. Therefore, though OSOITE project result is very informative for the promotion of our application research, it is difficult to apply their results directly if the viewpoint is to be, “that it can be quickly introduced into a disaster site that has urgent need, is maintenance-free, and is able to withstand continuous operation” which is the goal this research aims for. Moreover, research on an interesting sensor network that aims to acquire victim information in the event of a disaster is also underway, in which new proposals about position estimation and dynamic network configuration methods are made . The intention of this system, whose main purpose is to triage victims, is to provide sensor nodes to victims. Following the goal of this research of a wide-area sensor network system useful for grasping the situation at a disaster site, this system is positioned as a useful existing system which can provide important victim information data. The data obtained from the system is mashed up with other data and made accessible to users.
As stated above, the technologies to be developed by our application research are ones which can be integrated with, or complement, previously developed technologies that are relevant.
