Energy-efficient object tracking algorithm in wireless sensor networks
An energy efficient tracking algorithm（EETA） was proposed,which reduced energy consumption in sensor network by introducing an event-driven sleep scheduling mechanism.EETA gave tradeoffs between real time and energy efficiency by letting a maximum number of sensor nodes outside tracing area stay asl...

| description | An energy efficient tracking algorithm（EETA） was proposed,which reduced energy consumption in sensor network by introducing an event-driven sleep scheduling mechanism.EETA gave tradeoffs between real time and energy efficiency by letting a maximum number of sensor nodes outside tracing area stay asleep,and reduced the computation complexity to O（N） by formulating the location predication of an object as a state estimation problem of sensor node,in-stead of building a complex model of its trajectory.Meanwhile,EETA located the object by using adaptive weighted cen-troid algorithm with complexity of O（N）.The method was evaluated with a network of 64 sensor nodes,as well as an analytical probabilistic model.The results demonstrate the effectiveness of the method. |
