Positioning service is one of Wireless Sensor Networks’ (WSNs) fundamental services. The accurate position of the sensor nodes plays a vital role in many applications of WSNs. In this paper, a 3D positioning algorithm is being proposed, using mobile anchor node to assist sensor nodes in order to estimate their positions in a 3D geospatial environment. However, mobile anchor node’s 3D path optim...

Localization is an essential issue in mobile networks because many applications require the mobile to know their locations with a high degree of precision. Various localization methods based on mobile anchor nodes have been proposed for assisting the mobile nodes to determine their locations. However, none of these methods attempt to optimize the trajectory of the mobile anchor node. Different ...

wireless sensor networks attracting a great deal of research interest. accurate localization of sensor nodes is a strong requirement in a wide area of applications. in recent years, several techniques have been proposed for localization in wireless sensor networks. in this paper we present a localization scheme with using only one mobile anchor station and received signal strength indicator tec...

This paper presents localization in wireless sensor networks (WSNs) in presence of obstacles using a mobile anchor. The proposed scheme uses a mobile anchor, which finds its location via global positioning system (GPS). The mobile anchor broadcasts its coordinate while it navigates through sensing region. The static sensor nodes receive beacon messages when the mobile anchor and sensor nodes ha...

Large Proxy Mobile IPv6 deployments would benefit from a functionality where a Mobile Access Gateway could dynamically discover a Local Mobility Anchor for a Mobile Node attaching to a Proxy Mobile IPv6 domain. The purpose of the dynamic discovery functionality is to reduce the amount of static configuration in the Mobile Access Gateway. This document describes several possible dynamic Local Mo...

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...

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...

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...

Mobile technology has helped to simplify networking by enabling multiple computer users to simultaneously share resources in a home or business without additional or intrusive wiring. A Mobile Network consists of hundreds or thousands of nodes and a small number of data collection devices. Localization of these mobile nodes is an essential issue in mobile networks because many applications requ...
