Localization Algorithms for Mobile Nodes for Three-Dimentional WSNs

Localization phase for sensor nodes is considered as a critical issue for Static and Mobile Wireless Sensor Networks (SWSNs & MWSNs) for Three-Dimensional (3D) in last decides. Several localization techniques have been introduced to provide position of sensor nodes, but a limited number of these algorithms have been proposed to accurately estimate the location of sensor nodes for mobile wireless sensor networks for three-dimensional. In this paper, we propose localization algorithms for mobile nodes in 3D. The algorithms based on DV-Hop and EDV-Hop techniques. The selected model is Random Way Point Mobility model. Our presented algorithms guarantees that the nodes estimate their own position with a butter localization accuracy in comparison to static scenarios. Moreover, the proposed simulation confirms that the introduced algorithms can significantly improve the localization error and localization coverage of algorithms in Mobile Wireless Sensor Networks for nodes in a Three- Dimensional.
