In reasoning mechanism, two kinds of strategy: heuristic forward and backward reasoning method are adopted, and blackboard structure which is a common dynamic data area being applied.

The transmission subsystem provides the foundation for the network's dynamic capability to transfer data over a highly dispersed, non-contiguous area.

This paper proposes a dynamic data filtering mechanism based on best-grid, and analyses the relationship between size of grid cell, quantity of grid in update area and unnecessary information.
