A wireless service grid technology-based remote sensing applicable service model

The existing technologies for remote sensing image processing are rather limited in both the capability of processing large amount of data and the methods for image processing. Applying wireless and grid technologies to remote sensing information processing, this paper puts forward a remote sensing application services model based on wireless service grid technology, with agent technology being one of the main technologies. The agent takes on users' tasks submission, transmission, processing, executing, and results retrieval. The grid is constructed by combining the wired net and wireless net. Single node failure doesn't influence the running of whole grid. Every grid service server can be supported with some service realization nodes downward, which can themselves be supported with some sub-nodes downwards. This model is validated by an experiment, and it is confirmed that this model can adapt to a huge amount of remote sensing information service requests. With the service speed and efficiency enhanced greatly, this model is expected to be widely applicable.
