aggregate query processing in sensor networks

Mar 10 2015 · In addition when the sensing areas of sensor nodes are disjoint the coordinator of each sensor becomes itself and we perform traditional aggregate query processing Thus the problem we are considering is a generalization of the traditional innetwork aggregation problem...We are a professional mining machinery manufacturer, the main equipment including: jaw crusher, cone crusher and other sandstone equipment;Ball mill, flotation machine, concentrator and other beneficiation equipment; Powder Grinding Plant, rotary dryer, briquette machine, mining, metallurgy and other related equipment. which can crush all kinds of metal and non-metallic ore, also can be dry grinding and wet grinding.If you are interested in our products or want to visit the nearby production site, you can click the button below to consult us.Welcome to our factory to test machine for free!
