论文摘要
本文考虑了部署的无线传感器网络，以感知具有已知空间统计配置文件的环境变量。我们建议使用空间轮廓的其他信息来改善传感器的传感范围，同时允许其感应精度具有一定的公差。我们表明，此信息的使用改善了总WSN的感应性能。为此，我们首先得出各种性能指标的分析表达式，以衡量WSN的传感性能的改善。然后，我们使用数值结果定量地讨论传感收益。
This paper considers a wireless sensor network deployed to sense an environment variable with a known spatial statistical profile. We propose to use the additional information of the spatial profile to improve the sensing range of sensors while allowing some tolerance in their sensing accuracy. We show that the use of this information improves the sensing performance of the total WSN. For this, we first derive analytical expressions for various performance metrics to measure the improvement in the sensing performance of WSN. We then discuss the sensing gains quantitatively using numerical results.
