| 英文摘要: |
| Mobile anchors are widely used for localization in WSNs. However, special properties over 3D terrains limit the implementation of them. In this paper, a novel 3D localization algorithm is proposed, called 3DT-PP, which utilizes path planning of mobile anchors over complex 3D terrains, and simulations based upon the model of mountain surface network are conducted. The simulation results show that the algorithm decreases the position error by about 91%, 8.7% and lowers calculation overhead by about 75%, 1.3%, than the typical state-of-the-art localization algorithm (i.e., ‘MDS-MAP’, ‘Landscape-3D’). Thus, our algorithm is more potential in practical WSNs which are the characteristic of limited energy and 3D deployment. |
