ATTS-DF: Adaptive tracking solution to the target for data fusion in wireless sensor networks

Wireless sensor networks are composed of many sensor nodes limited to residual energy. The sensor nodes are randomly scattered within in the ranger monitoring and sending - receiving data by radio waves. The measured data often contains the same information, and sending to base station causes the waste of energy of sensor nodes and the risk of congestion. According to the statistics, the energy consumed by transceiver radio signals is many times greater than the energy consumes to process other tasks of sensor node including the calculation on the sensor node. In this paper, we propose algorithms installed on the sensor nodes to monitor non-cyclical target fixed, which base on the fluctuation of the target when it exceeds the threshold. Moreover, algorithm control sensor nodes measures just in time fluctuations exceeded targets need to measure.
