Localization in wireless sensor networks (WSNs) not only provides a node with its geographical location but also a basic requirement for other applications such as geographical routing. Although a rich literature is available for localization in static WSN, not enough work is done for mobile WSNs, owing to the complexity due to node mobility. Most of the existing techniques for localization in ...

In wireless sensor networks (WSNs), many applications require sensor nodes to obtain their locations. Now, the main idea in most existing localization algorithms has been that a mobile anchor node (e.g., global positioning system-equipped nodes) broadcasts its coordinates to help other unknown nodes to localize themselves while moving according to a specified trajectory. This method not only re...

This specification defines a new mobility option, the Quality-ofService (QoS) option, for Proxy Mobile IPv6. This option can be used by the local mobility anchor and the mobile access gateway for negotiating Quality-of-Service parameters for a mobile node’s IP flows. The negotiated QoS parameters can be used for QoS policing and marking of packets to enforce QoS differentiation on the path betw...

This memo defines a portion of the Proxy Mobile IPv6 Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, the Proxy Mobile IPv6 MIB can be used to monitor and control the mobile access gateway (MAG) and the local mobility anchor (LMA) functions of a Proxy Mobile IPv6 (PMIPv6) entity.

Localization has become one of the mandatory services in wireless sensor networks (WSNs) while dealing with critical operations such as coverage, deployment, routing, target tracking and rescue operations. Since the necessity of WSN has increased drastically to provide best solution with accurate results of sensor nodes, it mainly depends on the WSN node localization. This paper initially descr...

Localisation is one of the most important issues in wireless sensor networks, because the location information is typically useful for coverage, deployment, routing, location service, target tracking and rescue operations in wireless sensor networks. The localisation protocols are classified into two categories: range-based protocol and range-free protocol. The range-based protocols employ dist...

Up to now a considerable number of studies have been conducted on the localization methods for stationary wireless sensor networks (WSNs). However little attention has been given to the localization scheme for a mobile wireless sensor network (MWSN) where all sensor nodes are moving. In this paper, we propose a self-localization scheme with relay nodes which transmit the information from an anc...

This document discusses security threats to network-based localized mobility management. Threats may occur on two interfaces: the interface between a localized mobility anchor and a mobile access gateway, as well as the interface between a mobile access gateway and a mobile node. Threats to the former interface impact the localized mobility management protocol itself.

While localization is essential to many applications, there are quantities of wireless nodes whose accurate locations remain unknown or hard to tell. As a remedy, this paper is leveraging a GPS-capable Android handset that features portability and sufficient computing capability to collect data and display localization results thereof. Our objective is to locate the unknown nodes under irregula...
