On Demanding Information Acquisition in Sensor Network

Information acquisition is the key part in sensor network. When there are many sensors wired or wireless organized, people have to make tradeoff between frequency and accuracy. Temperature sensors are widely used in monitoring the environment temperature of large grain depots. The timely and efficient temperature monitoring should be ensured so as to handle the large amount of temperature sensors. This paper intends to propose on demanding information acquisition method to monitor the temperature other than check the temperature site by site. Simulation and experiment showed that the method is of large benefit
