| 摘 要： | 针对环境监测中异常区域分布不均匀，以及无线传感器网络中节点密集、部署冗余的特点，提出了基于嵌套网格的节能部署方法，并依据物理参数梯度设计了非均匀部署节点算法．对其环境监测应用——森林火灾监测，进行了性能分析和Matlab仿真验证．结果表明，该方法可以有效地节约网络的能量，快速发现异常区域，并能详细描述异常区域的参数分布状况．

| Abstract: | Taking into consideration that the abnormal areas aren't distributed uniformly and nodes in wireless sensor networks(WSNs) are dense and redundant,an energy-efficient deployment strategy named Nested Grid based Energy-efficient Deployment Algorithm(NGEDA) is presented for WSNs.A non-uniform deployment algorithm is designed based on physical parameter gradient distribution.The performance of NGEDA employed in environment monitoring(e.g.forest fire monitoring) is analyzed and validated by Matlab simulation.Results show that NGEDA is energy-efficient,can quickly find the abnormal area,and can describe its parameter distribution in detail. |
