基于Hilbert空间填充曲线的WSN移动汇聚节点轨迹设计
WSN mobile aggregation node track design based on Hilbert space filling curve
摘要
Abstract
Since the data loss rate and energy consumption are high due to that some nodes in wireless sensor network (WSN)can′t be accessed,a novel approach of using Hilbert space filling curve to design the mobile aggregation node track for WSN is proposed. The Hilbert curve depending on the size of network is used to analyzed the mobile aggregation node track. The order of Hilbert curve is calculated based on node density to determine the dimension of the aggregation node track. The NS⁃2 simulation is used to evaluate the effectiveness of network coverage and scalability. The simulation results show that the mobile node coverage rate is reduced with the increase of the nodes quantity of the whole network,and the proposed Hilbert curve based on density is superior to the Hilbert curve based on size in the aspects of network coverage,packet transfer ratio and average energy consumption.关键词
