Non-line-of-sight Node Localization based on Semi-Definite Programming in Wireless Sensor Networks
Hongyang Chen, Kenneth W. K. Lui, Zizhuo Wang +2
An unknown-position sensor can be localized if there are three or more anchors making time-of-arrival (TOA) measurements of a signal from it. However, the location errors can be ve…

Mobile Anchor Assisted Node Localization for Wireless Sensor Networks
Hongyang Chen, Qingjiang Shi, Pei Huang +2
In this paper, a cooperative localization algorithm is proposed that considers the existence of obstacles in mobilityassisted wireless sensor networks (WSNs). In this scheme, a mob…
