| 针对水下传感器网络的部署方式,设计活动受限三维水下传感器网络节点定位算法(localization foractive-restricted UWSN,简称LAR).LAR 利用水下节点活动受限的特点辅助定位,通过分层定位的实施方式得到部署区域内全部节点的位置,并根据水下传感器网络中的节点移动规律,设计动态环境下的补偿机制.LAR 过程简单、易于实现,仿真结果表明其定位误差明显小于现有算法. |

| Abstract: |
| A localization algorithm for active-restricted 3-dimensional underwater sensor networks called LAR is proposed. It makes use of active-restricted sensor nodes' mobility to assist localization, and implements hierarchical mechanism to localize all the deployed sensor nodes. A compensation method for dynamic environment is also proposed based on the characteristics of mobile underwater sensor nodes. The obtained simulation results indicate that LAR is an effective scheme for underwater sensor network localization. |
