The wireless sensor network is usually constituted by hundred or thousand nodes because sensor nodes are very cheap devices. In the wireless sensor network, multiple sensor nodes might detect the same event when they are randomly deployed on a large scale. The sensor nodes will consume a large amount of energy if they send the same event to the sink node independently, as in the traditional algorithm. In general, the detected device is a small and cheap device. Hence, the wireless sensor node usually has several detected devices, and it can detect large amounts of different information in an area when an event takes place.
