| 研究了n个静态节点随机分布在单位球上的三维超宽带无线传感网,利用Vapnik-Chervonenkis定理和Voroni棋盘格子覆盖传感区域,推导出了某个节点发射包含R比特的数据分组以多跳方式到达汇聚节点时的能量消耗上下界.研究表明,能量消耗的上下界与网络节点密度n成反比.因此,大规模密集超宽带无线传感网是更为可取的. |

| Abstract: |
| Considering a three dimensional TH-UWB wireless sensor network with n static identical randomly located sensor nodes in a sphere of volume normalized by one cubic meter, the formula for upper and lower bounds on the energy dissipation of some sensor node transmitting a data packet containing R bits to the sink node by multihop fashion are derived using Vapnik-Chervonenkis theory and Voroni tessellation covering sensor field.The main finding is that the upper and lower bounds on the energy dissipation are in inverse proportion to the node density n in the network.Thus,large-scale dense TH-UWB wireless sensor network is more preferable. |
