This paper considers the two-dimensional (2D) anchorless localization problem for sensor
networks in global positioning system (GPS)-denied environments. We present an efficient …

Multi-hop wireless sensor networks are widely used in many location-dependent
applications. Most applications assume the knowledge of geographic location of sensor …

Localization is one of the most fundamental problems in wireless sensor networks, since the
locations of the sensor nodes are critical to both network operations and most application …

Position awareness is very important for many sensor network applications. However, the
use of Global Positioning System receivers to every sensor node is very costly. Therefore …

Wireless sensor networks are used in many location-dependent applications. The location of
sensor nodes is commonly carried out in a distributed way for energy saving and network …

There are various applications in wireless sensor networks which require knowing the
relative or actual position of the sensor nodes. Over the past few years, there have been …

Node localization has played an important role in wireless sensor networks. In this paper,
cooperative localization using received signal strength (RSS) measurements is addressed …

Due to single reference information priority, poor network topology adaptability, low
