Localization techniques are becoming key to add location context to the Internet-of-Things
(IoT) data without human perception and intervention. Meanwhile, the newly emerged low …

Localization plays an important role in the field of Wireless Sensor Networks (WSNs) and
robotics. Currently, localization is a very vibrant scientific research field with many potential …

The need for accurate, fast, and reliable indoor localization using wireless sensor networks
(WSNs) has recently grown in diverse areas of industry. Accurate localization in cluttered …

For indoor localization based on wireless sensor networks, the transmission of wireless
signals can be disrupted by obstacles and walls. This situation, called non-line-of-sight …

Impulse radio ultrawideband ranging has recently received significant attention due to the
high accuracy it can achieve. Although most research efforts have focused on ranging in …

One hurdle to accurate indoor localization using time-based networks is the presence of
Non-Line-Of-Sight (NLOS) and multipath signals, affecting the accuracy of ranging in indoor …

Due to increasing urban population and growing number of motor vehicles, traffic
congestion is becoming a major problem of the 21st century. One of the main reasons …

In this paper, a technique for modeling propagation of ultrawideband (UWB) signals in
indoor or outdoor environments is proposed, supporting the design of a positioning systems …

Accurate ranging and localization in non-line-of-sight (NLOS) conditions is an open
research problem. In indoor environments, NLOS causes ranging and location errors due to …

In this paper, we consider the problem of mobile location estimation in a rough wireless
environment. To mitigate the non-line-of-sight (NLOS) effects, the transition between the line …
