To manage such a very large scale commodities, they need to install sensor network with MapReduce of hadoop; since the sensor net-work generates a huge amount of data. The ranch is divided into several patterned regions and a lot of hubs are installed in there for retrieving the sensor data. However, when the sensor moves to an overlapped area among some hubs, the sensor data are transmitted to all hubs covering the area. Obviously, these data is redundant.
