چکیده
This article presents a hybrid scheme for 3-D localization in mobile Wireless Multimedia Sensor Networks. For minimizing the localization error, this paper proposes efficient trajectory estimation patterns and periodic calibration of nodes’ position. Within this hybrid solution, that uses inertial measurements for location determination, the nodes’ position is periodically validated using an anchor-based algorithm. Offering a very low localization error, the proposed scheme significantly lowers the delay of localization, very important to mobile nodes, and provides an insignificantly increase in network traffic and energy consumption during the localization procedure.
