Spatial Interpolation of Weather Sensor Data on P2P Network

Recently, environment monitoring system attracts attention because global and/or local disasters such as global warming problem, air pollution, heavy rain and flood etc. occur everywhere. In addition, some people and companies have a weather sensor and broad band internet service become widespread as weather sensor and internet service cost lower. Many of these existing sensor network are operated by Server-Client model. However, it is difficult to manage a number of distributed sensors, and this model is weak for fault tolerance. We adopt P2P model in order to correct the necessary information effectively. On the other hand, the number of weather sensors cannot be satisfied enough to cover an arbitrary point on the earth though the users of such a weather sensor network are keen to know the information around them. In this paper, we present the method of spatial interpolation of the weather sensor data on P2P network based on location information.
