↑ Return to Objective and Targets


In this project, we will implement the following items within three years between 2012 and 2014.

  1. Demand Addressable Network

    1. Demand Interpreter: Technology that interprets a user’s abstract demands instantaneously, and expands these into a combination of concrete sub-demands
    2. Demand Addressing: Technology that dynamically finds the resources, i.e., networked sensors and/or local DBs, which hold the desired sensing data and through the use of expanded sub-demands or a combination of them without referring to any centrally-managed directories or other resources
    3. Data Mash-up Network: Network technology that combines (mashes up) the acquired data in the network, and displays them to the user
    1. Wireless Sensor Network Having Environment Adaptability

    2. Scenario compiler: Technology that generates “roles” that should be fired in the sensor nodes from a “scenario description” created by the user. The generated roles should be transmitted to corresponding sensor nodes via wireless communication. By changing the scenario description, the behavior of sensor nodes can be customized even after installation.
    3. Sensor node capable of changing its role dynamically: This sensor node has a mechanism to dynamically start a “role” in response to meeting a trigger condition, according to environmental changes and/or user requests.
  2. Prototype System

    We integrate the above technologies to implement a prototype of maintenance-free wide-area sensor network, which can be quickly introduced into a disaster site and efficiently monitor the disaster situation. We also conduct demonstration experiments on the prototype. This system also brings about a function that combines (mashes up) the information generated by existing fire fighting and disaster-prevention systems, and displays the mashup information to the users.
