| 摘 要： | 针对实际应用中传感器节点采样频率不同的特点,提出了一种传感网中基于能量平衡的数据收集树算法(an energy balancing and tree-based data gathering algorithm,EBDGA).EBDGA在基站集中式的构建是以本基站为根结点、基于能量平衡的生成树,根据节点的采样频率定制生成树中子节点加入的策略.仿真实验表明,在这种特定的网络模式下,EBDGA比传统的数据收集树算法PEDAP和PEDAP-PA具有更好的能量平衡特性,提升了能量性能.

| Abstract: | In view of the nodes' sampling frequencies in real applications being different,an energy balancing and tree-based data gathering algorithm(EBDGA) in wireless sensor networks was proposed.EBDGA is executed centrally on the base station to create an energy balancing tree with this station as its root.The selection policy of each children node takes the node's sampling frequency into account.Simulation results show that under this special network mode,EBDGA achieves more notable energy balancing capability than traditional algorithms,PEDAP and PEDAP-PA,thus enhancing energy efficiency. |
