In ad hoc wireless networks, devices that normally cannot directly communicate route their
messages through intermediate nodes. The number of those nodes is called hop count, a …

Hop Count based distance estimation is an important element for localization of devices in
mobile ad hoc networks. Deriving distance estimates from hop counts is prone to error …

Distributed localization algorithms for nodes in ad hoc networks are essential for many
applications. A major task when localizing nodes is to accurately estimate distances. So far …

DV-Hop algorithm produces errors in location estimations due to inaccurate hop size. We
propose a novel localization scheme based on DV-Hop to improve positioning accuracy with …

We propose a range-free localization algorithm for a wireless ad-hoc network utilizing the
hop-count metric's ability to indicate proximity to anchors (ie, nodes with known positions). In …

With the increase in demand for ad hoc networks, localization has become a fundamental
and essential solution to manage networks. Among existing localization algorithms, DV-Hop …

It is of paramount importance to obtain accurate node positions in ad hoc networks for
various location-based services. Hop-count based localization provides a low-cost and …

This paper addresses the problem of nodes localization in wireless ad hoc networks. Two
types of nodes are considered: nodes with self-locating capability like GPS and nodes with …

In this paper, we propose a novel range-free localization algorithm tailored for mobile ad hoc
networks (MANET) s. In contrast to most existing range-free techniques, we take into account …

We discuss the effect of adding nodes on the location accuracy of Ad-Hoc networks. All
results are obtained by analyzing the Cramér-Rao Lower bound. We show that for planar …
