Sensor network is needed for managing huge ranch with a very large number of commodities. In the ranch, there will be deployed a certain number of sensor hub for retrieving the sensor data sent by the sensor. The ranch will be divided into several patterned regions so that the sensor hub can cover the whole ranch area. It is unavoidable that there will be some overlapped area between sensor hubs, since 100% coverage is a must. Thus, when a sensor moves inside this area, there will be redundant sensing data received by hubs covering this overlapped area.
