The rapid progress of wireless communication and the availability ofmany small-sized, light-weighted and low-cost communication and computing devicesnowadays have greatly impacted the development of wireless sensor network.Localization using sensor network has attracted much attention for itscomparable low-cost and potential use with mon- itoring andtargeting purposes in real and hostile application scenarios. Currently, thereare many available approaches to locating persons-things based on globalpositioning system GPS and radio-frequency identification RFID technologies.However, in some application scenario, e.g., disaster rescue application, suchlocalization devices may be damaged and may not provide the locationinformation of the survivors. The main goal of this paper is to design and develop arobust localization technique for human existence detection in case ofdisasters such as earthquake or fire. In this paper, we propose a 3-Dlocalization technique based on the hop-count data collected from sensoranchors to estimate the location of the activated sensor mote in 3-D coordination.Our algorithm incorporates two salient features, cubic-based outputand event-triggering mechanism, to guarantee both improved accuracy and power efficiency. Both simulation and experimental results indicatethat the proposed algorithm can improve the localization precision of the humanexistence and work well in real environment.
