A 3 - dimensional Localization Algorithm for Mobile Wireless Multimedia Sensor Networks

Abstract

This article exposes a specific localization algorithm for Wireless Multimedia Sensor Networks. Its hybrid structure is designed for 3-dimensional positioning of the multimedia sensor nodes using in-situ measurements and minimizes the error of localization by proposing an efficient trajectory estimation pattern along with a periodic calibration of the sensor nodes’ coordinates. A periodic validation of the coordinates is performed by implementing a classical anchor-based localization algorithm. Providing a decreased error of localization, the suggested algorithm considerably reduces the localization delay, essential to mobile nodes, and offers an insignificant rise in network traffic as well as energy consumption throughout the positioning process. To further reduce the overall energy consumption, an adaptive sampling rate technique is proposed. Keywords— wireless multimedia sensor network, mobile nodes, 3-D localization, inertial measurements
