To support network mobility in wireless network, NEMO BSP is proposed by IETF. Mobility support paradigm is going to move from the MN to Network. PMIPv6 is the latest protocol based on local mobility management and network-based mobility. The mobile node can freely move between PMIPv6 network and mobile network. The previous NEMO protocols based on PMIPv6 cannot support this kind of mobility due to...
While gracefully combining FMIPv6 and HMIPv6 together, F-HMIPv6 enables the best performance in terms of handover latency and signaling overhead. Recently, to protect F-HMIPv6, Kang and Park proposed a security scheme. This scheme successfully achieves seamless integration with FHMIPv6 while providing the session key exchange as well as the mobile node authentication. In this paper, Kang-Park's scheme...
As the era of NGN comes, the combination of mobile communication and fixed internet becomes the great goal of communication personalization, namely mobile internet. So it is of sense to study the internet applications in mobile condition. In this paper, we focus on PPStream (PPS) system with UDP (U-PPS) and TCP (T-PPS) respectively for comparison in mobile environment, mainly through the simulation...
With the rapid development of wireless technologies and increasing communication need of people in ubiquitous environment, some handoff schemes and improvements were proposed by IETF in order to support mobility effectively. In addition, mobile Stream Control Transmission Protocol (mSCTP) proposed by IETF is a new transport protocol supporting mobility and with a built-in feature called Multi-homing...
This paper explores ways to enhance services provided to a user, based on the user's own behavior and context. The assumption is that the user continues to simply use data communication services, while the service provider (SP) mines the content exchanged over the communication pipes for information that can be used to further personalize the same service or other services to which the user has subscribed...
Resource discovery is a key component of P2P network. The resource discovery algorithm complexities of classic models, such as Chord and Pastry, are always equal or even bigger than O(logN), which means while the network scale increasing, the time delay will also increase rapidly without a ceiling. In this paper, we present a new P2P network model for resource discovery. Firstly, we take location-aware...
Future networks are envisioned to satisfy the user needs and improve their quality of experience. This requires the networks to support context-aware information, where context of the user, session, network and environment will greatly influence the way the session is delivered: new approaches are required to deal with the overall context information and network reaction to constantly context changes...
Self-configuration management of mobile ad-hoc networks (MANETs) depends upon the hierarchical architecture and topology change of the network. By analyzing role shift and behavior changes of nodes in the clustering-based MANETs, a self-configuration management model is proposed in this paper. In view of unpredictability of the node behavior, a cluster unit provides the auto-configuration mechanisms...
Proxy mobile IPv6 (PMIPv6) is designed to provide a network-based localized mobility management protocol, but it does not handle the global mobility of hosts. In this paper, we propose a location management scheme based on domain name system (DNS) for PMIPv6. In this proposed scheme, DNS as a location manager provides PMIPv6 for global mobility. In addition, a paging extension scheme is introduced...
With the lead of the Rich Communication Suite (RCS) initiative under the GSMA umbrella, Orange wants to drive the commercial introduction of a new convergent communication suite for the mass market. The underplayed IMS core network provide a powerful infrastructure for the deployment of such innovative suite addressing both mobile and internet access. The commercial specifications are based on the...
This paper introduces a new method to implement the SUPL Location Platform defined in the SUPL specification. SUPL (Secure User Plane Location) is designed by OMA (Open Mobile Alliance) for the deployment of Location Based Services. SUPL is an open LBS specification, which supports various positioning technologies(eg: A-GPS, cell-Id, EOTD). SLP (SUPL Location Platform) is the Entity responsible for...
The aim of this article is to present a novel handover algorithm to decrease the handoff latency in all-IP based future heterogeneous mobile communication system (FHMCS). The reduction in handoff latency is achieved by employing mobile network discovery technique which will decrease the delays due to movement detection, new care of address configuration and duplicate address detection (DAD). The decrease...
Mobile networks are increasingly important in land-, sea-and air-based military scenarios. The interest in supporting network mobility for Internet protocol (IP) networks has led to the network mobility (NEMO) protocol extensions being proposed for IP within the IETF. These extensions are based on the work already completed on host mobility for mobile IP (MIP). The current work is based on the use...
Mobile P2P media streaming is a very interesting research topic. We design a real P2P system based mobile simulation measurement platform. Based on the captured traces of PPStream, four aspects are reported: protocol blackouts, unavailable data (UD), performance of data fetching and sharing, and neighbor stability. A simple model is presented to analyze the UD in handover. According to the model,...
As IEEE 802.11 matures and other wireless access technologies are introduced (such as IEEE 802.16e), the emergence of Internet Protocol as a de facto standard for transport allows users to have increasing choice about their mobile access. This effect will not only increase competition amongst cellular network providers it will also increase competition with other stakeholders and operators in the...
IETF suggested MIPv6 and HMIPv6 to provide the mobility support for the IPv6 based environment. HMIPv6 proposed a mobility anchor point to reduce the BU cost caused by the BU process toward the HA. However, HMIPv6 has a problem in the high mobility environment because of the frequent BU processes. This paper proposes a selective MAP binding scheme to reduce the number of unnecessary local BU process...
The IEEE 802.16 standard was designed to provide rapid deployment, high bandwidth, and low-cost fixed broadband wireless access (BWA). As an enhancement, IEEE 802.16e standard was developed for further supporting mobility. As media streaming services are extending to mobile stations, it is crucial to minimize the handover delay and service disruption time so as to maintain the sustained connection...
Nowadays, the researches about the IP connectivity for mobile node are in progress. In particular, mobile IP and hierarchical mobile IP are well-known methods for these researches. In these works, mobile nodes are assumed to be always in the active state whether they move to the other cell or not. However, since more than 95% of mobile nodes are moving in the idle state actually, they should change...
Voice over IP (VoIP) has already gained significant popularity as one of the most important services in the Internet. Ability to make calls, which are very cheap or even free of charge, allows this technology to be considered as a possible substitution of the existing telephony. However, the existing way of utilization of this service has one considerable disadvantage preventing global users to shift...
Providing a seamless handoff and quality of service (QoS) guarantees is one of the key issues in real-time services. Several IPv6 mobility management schemes have been proposed and can provide uninterrupted service. However, these schemes either have synchronization issues or introduce signaling overhead and high packet loss rate. This paper presents a scheme that reduces the handoff latency based...
