Since all anchor-based range-free localization algorithms require estimating the distance from an unknown node to an anchor node, such estimation is crucial for localizing nodes in environments as wireless sensor networks. We propose a new algorithm, named EDPM (Estimating Distance using a Probability Model), to estimate the distance from an unknown node to an anchor node. Simulation results sh...
Mobile ad hoc networks are networks composed of wireless devices to create a network with the ability for self-organization. These networks are designed as a new generation of computer networks to satisfy some specific requirements and with features different from wired networks. These networks have no fixed communication infrastructure and for communication with other nodes the intermediate no...
A tracking scenario comprising a mobile emitter node moving through an indoor environment covered by multiple anchor receivers is investigated in this work. A localization method based on received signal strength indicators (RSSI) and making use of the extended Kalman filter (EKF) and circularly polarized (CP) antennas is proposed. The EKF implements the position-velocity (PV) model, which assu...
This document describes a runtime local mobility anchor assignment functionality and corresponding mobility options for Proxy Mobile IPv6. The runtime local mobility anchor assignment takes place during a Proxy Binding Update and a Proxy Binding Acknowledgement message exchange between a mobile access gateway and a local mobility anchor. The runtime local mobility anchor assignment functionalit...
Proxy Mobile IPv6 is a network-based mobility management protocol which is attractive as it does not require the participation of mobile nodes in mobility-related signaling. Unlike the host based approaches like Mobile IPv6, in PMIPv6 the Mobility Access Gateway (MAG) is responsible for tracking the movements of Mobile Node (MN) and to initiate the handover process. In this study, a novel metho...
Localization is one of the most important factor in wireless sensor networks as many applications demand position information of sensors. Recently there is an increasing interest on the use of mobile anchors for localizing sensors. Most of the works available in the literature either looks into the aspect of reducing path length of mobile anchor or tries to increase localization accuracy. The c...
In this paper, we address a system that can accurately locate and monitor work tools in complex assembly process, such as automotive production. Our positioning monitoring is positioned by combined sensor of the UWB module MEMS IMU (inertial measuring unit) based on extended Kalman filter. The provides calibration information. proposed method incorporates to compensate for errors only occur thr...
Localization of mobile sensor nodes is indispensable for underwater sensor networks. For example, in aquatic environment monitoring applications, localization is a must-do task in order to get useful location-aware data. Location information is also required for geo-routing, which is proved to be more scalable and efficient in mobile underwater sensor networks. So far, only a limited number of ...
Localization in a wireless sensor network (WSN) becomes important for many modern applications, like landslide detection, precision agriculture, health care, and so forth. The more precise the position of an anchor node is, the more accurate the localization of a sensor node can be measured. Since the Global Positioning System (GPS) device cannot work properly indoor, some existing localization...
Proxy Mobile IPv6 is the IETF Standard for network-based mobility management. In Proxy Mobile IPv6, mobile nodes are topologically anchored at a Local Mobility Anchor, which forwards all data for registered mobile nodes. The setup and maintenance of localized routing, which allows forwarding of data packets between two mobile nodes’ Mobility Access Gateways without involvement of their Local Mo...
