In this paper cost analysis of a three-layer hierarchical model and HMIPv6 is done. The objective of this work is to examine the signaling cost, tunneling cost and packet dropping probability at top level anchor agents of a Multi-level (3 levels) architecture and HMIPv6 and to observe in what scenario multiple levels of hierarchy can give better performance over HMIPv6. Analysis of both the mod...

We describe a powerful and different approach to solve the localization problem of sensor networks with a very few anchor nodes (we define anchor nodes as those sensors that are equipped with GPS receivers so that they are fully aware of their location). The triangulation procedure (employed usually to solve this problem) fails when we don’t have the anchor nodes lying close to each other, sinc...

—Localizing machine type communication (MTC) devices or sensors is signi cantly important due to the increasing popularity of machine to machine (M2M) communication networks in location-based applications such as health monitoring, rescue operations, vehicle tracking, and wild re monitoring. Moreover, ef cient localization approaches for sensor-based MTC devices reduce the localization error an...

We describe a concept to employ Trusted Computing technology to secure Conditional Access Systems (CAS) for DVB. Central is the embedding of a trust anchor, e.g. a trusted platform module (TPM) into the set-top box or Conditional Access Module. Various deployment scenarios exhibit possibilities of charging co-operation with mobile network operators (MNO) via trusted mobile devices, or with othe...

mobile ad hoc networks (manets) are composed of mobile stations communicating through wireless links, without any fixed backbone support. in these networks, limited power energy supply, and frequent topology changes caused by node mobility, makes their routing a challenging problem. tora is one of the routing protocols that successfully copes with the nodes’ mobility side effects, but it doesn’...

Mobile IPv6 (MIPv6) is a work in progress IETF standard for enabling mobility in IPv6 networks and is expected to have wide deployment. We investigate an integrated mobility and service management scheme based on MIPv6 with the goal to minimize the overall network signaling cost in MIPv6 systems for serving mobility and service management related operations. Our design extends IETF work-in-prog...

This paper proposes a handover scheme supporting MultiProtocol Label Switching (MPLS) in a Proxy Mobile IPv6 (PMIPv6) domain that improves the mobility and gives Quality of Service (QoS) and Traffic Engineering (TE) capabilities in wireless access networks. The proposed scheme takes advantages of both PMIPv6 and MPLS. PMIPv6 was designed to provide NETwork-based Localized Mobility Management (N...

In this paper, a mobility-aware Dual Pointer Forwarding scheme (mDPF) is applied in Proxy Mobile IPv6 (PMIPv6) networks. The movement of a Mobile Node (MN) is classified as intra-domain and inter-domain handoff. When the MN moves, this scheme can reduce the high signaling overhead for intra-handoff/inter-handoff, because the Local Mobility Anchor (LMA) and Mobile Access Gateway (MAG) are connec...

In Mobile IPv6, each packet sent and received by a mobile node contains its home address. As a result, it is very easy for an eavesdropper or for a correspondent node to track the movement and usage of a mobile node. This paper proposes a simple and practical solution to this problem. The main idea is to replace the home address in the packets by a temporary mobile identifier (TMI), that is cry...

Proxy Mobile IPv6 (PMIPv6) was standardized by the Internet Engineering Task Force (IETF) NetLMM WG as a Network-based Mobility management protocol. This protocol allows the Mobile Node (MN) to maintain service connectivity while moving within the PMIPv6 domain. PMIPv6 mobility management is different from the Host-based Mobility management protocols; where the mobility signaling management is ...
