Line-of-sight and non-line-of-sight links for dispersive terahertz wireless networks
APL Photonics, 2021 Despite the rapidly growing interest in exploiting millimeter and terahertz waves for wireless data transfer, the role of reflected non-line-of-sight (NLOS) paths in wireless networking is one of the least explored questions.

Localization and dynamic link detection for geographic routing in non-line-of-sight (NLOS) environments [PDF]
EURASIP Journal on Wireless Communications and Networking, 2011 Abstract IEEE 802.15.4a networks can provide the geographic routing solution with high location accuracy for the indoor environments. However, in the non-line-of-sight (NLOS) environments, the IEEE 802.15.4a networks may have a large scale location error and an unstable communication link. In this article, we propose a location estimation and
