This paper focuses on the problem of source localization using time-difference-of-arrival
(TDOA) measurements in both 2-D and 3-D spaces. Different from existing studies where the …

We propose a class of convex relaxations to solve the sensor network localization problem,
based on a maximum likelihood (ML) formulation. This class, as well as the tightness of the …

Positioning in Wireless Communications Systems explains the principal differences and
similarities of wireless communications systems and navigation systems. It discusses …

Wideband ranging is essential for numerous emerging applications that rely on accurate
location awareness. The quality of range information, which depends on network intrinsic …

Device-to-device (D2D) communication in cellular networks is a promising concept that
permits cooperation among mobile devices not only to increase data throughput but also to …

In recent years, there has been a growing interest in localization algorithms for indoor
environments. In this paper, we have developed an enhanced filtering method for indoor …

Motivated by the recent advances on internet of things (IoT) and the importance that location
information has on many application scenarios, this article offers references to theoretical …

Intelligent Transportation Systems (ITS) have emerged to utilize different technologies to
enhance the performance and quality of transportation networks. Many applications of ITS …

Synchronization is a key functionality in wireless networks, enabling a wide variety of
services. We consider a Bayesian inference framework whereby network nodes can achieve …

In this paper, we aim to determine the location information of a node deployed in Wireless
Sensor Networks (WSN). We estimate the position of an unknown source node using …
