Abstract The Heterogeneous Ad Hoc Networks (HANETs) are important components of the
Internet of things, which become an inevitable trend in the future researches and …

Point positioning of a signal source is feasible if it is not far from the sensors and direction of
arrival (DOA) localization is only applicable if it is distant. Point positioning and DOA …

The location of the sensor node is critical in wireless sensor networks (WSN) as the
information acquired by the sensor node may be worthless without knowing its source …

The global positioning system (GPS), which provides ubiquitous location-awareness with a
constellation of satellites, has become an instrumental function of multiple mass-market …

Cluster-based routing is the most common routing approach to achieve energy efficiency in
wireless sensor networks. However, optimal determination of cluster heads is NP-hard …

This paper researches the cooperative localization in wireless sensor networks (WSNs) with-
periodic angle-of-arrival (AOA) measurements. Two types of localizers are developed from …

Determining the accurate locations of randomly deployed sensors in a given geographical
region is a critical problem in the field of Wireless Sensor Networks. Various approaches …

Solving the nonconvex and non-differentiable objective function of traditional range-free
node localization methods will result in low localization accuracy or high computational …

DV-Hop localization algorithm has greater localization error which estimates distance from
an unknown node to the different anchor nodes by using estimated average size of a hop to …

Location information is a crucial enabler for many applications of Wireless Sensor Networks
(WSN) such as oil and gas explorations, intrusion detection, and road traffic tracking. For …
