Objectives
 Integrate the current monitoring system
of flood events and add the function of
remote control to proposed system.
 Improve the original network for data
collection to the data service network.
 Apply the multi-casting technology to
reduce the loading of data transmission
and develop the network environment for
a lot of end users.
