Object tracking in wireless sensor networks using an itinerary-based method

摘要: In the Internet of Things, smart things communicate with each other, and sensed data are aggregated queried for satisfying certain requests end-users. Target tracking is a typical important application wireless sensor networks. Considering energy efficiency object accuracy, we propose novel method based on pre-defined itinerary. Energy can be reduced due to effectively selecting collaborative node activate. The accuracy improved because prediction movement range confined into adjacent itineraries according current position direction object. number activated sensors involved in target will decreased save prolong lifetime network. Theoretical analysis shows that our technique energy-efficient accurate compared traditional techniques.
