Abstract: In Next Generation Wireless Networks (NGWN), lots of information, such as voice and video data, will be used in All-IP networks. It is important note that seamless service for users and handoff between heterogeneous networks must be taken into account in such environments. Therefore, in this paper, we propose a SePH(Seamless Proxy based Handoff) using PMIPv6-based proxy model which is enable to improve the performance of handoff in NGWN. The SePH can efficiently support seamless and IP-based mobility by reducing the search process. The performance results show that our proposed scheme outperforms in terms of QoS (Quality of Service) such as throughput, handoff latency, packet loss, and signaling overhead comparing to the existing schemes.

TL;DR: This paper proposes an Enhanced Security scheme for FPMIPv6(ESS-FP), based on the CGA method and the pubilc key Cryptography, ESS-FP provides the strong key exchange and the key independence in addition to improving the weaknesses for F PMIPv 6.
Abstract: In PMIPv6-based network, mobile nodes can be made smaller and lighter because the network nodes perform the mobility management-related functions on behalf of the mobile nodes. The one of the protocols, Fast Handovers for Proxy Mobile IPv6(FPMIPv6)[1] has studied by the Internet Engineering Task Force(IETF). Since FPMIPv6 adopts the entities and the concepts of Fast Handovers for Mobile IPv6(FMIPv6) in Proxy Mobile IPv6(PMIPv6), it reduces the packet loss. Conventional scheme has proposed that it cooperated with an Authentication, Authorization and Accounting(AAA) infrastructure for authentication of a mobile node in PMIPv6, Despite the best efficiency, without begin secured of signaling messages, PMIPv6 is vulnerable to various security threats such as the DoS or redirect attAcks and it can not support global mobility between PMIPv. In this paper, we analyze Kang-Park & ESS-FH scheme, and then propose an Enhanced Security scheme for FPMIPv6(ESS-FP). Based on the CGA method and the pubilc key Cryptography, ESS-FP provides the strong key exchange and the key independence in addition to improving the weaknesses for FPMIPv6. The proposed scheme is formally verified based on Ban-logic, and its handover latency is analyzed and compared with that of Kang-Park scheme[3] & ESS-FH and this paper propose inter-domain fast handover sheme for PMIPv6 using proxy-based FMIPv6(FPMIPv6).

TL;DR: A handover procedure of 3S is proposed, which demonstrates its superiority over the existing schemes in terms of handover latency and safety, and the safety, scalability, and seamless service for 3S.
Abstract: PMIPv6 has received considerable attention between telecommunications and the Internet communities and does not require active participation of the Mobile Node (MN) by way of network-based mobility management. In this paper, we are proposing a novel 3S scheme for building Scalable, Secure, and Seamless PMIPv6 domains. In the proposed scheme, all of the Mobility Access Gateways (MAGs) are acting as the Local Mobility Anchor (LMA) combining a virtual ring with another MAG. General hashing is used in the efficient distributionmapping between each MN and the MN’s LMA for all MAGs. Also, the MAG and the MN are authenticated using the symmetric key. Through mathematical analysis, we verify the safety, scalability, and seamless service for 3S. Furthermore, we propose a handover procedure of 3S, which demonstrates its superiority over the existing schemes in terms of handover latency.

TL;DR: In this paper, two kinds of schemes in analyzing of mobility management schemes are proposed, respectively, the signaling transfer and packet delivery procedures for each mobility management scheme are analyzed, respectively.
Abstract: Cost-effective mobility management for the roaming mobile users is very important in the seamless services on next-generation wireless network (NGWN). MIPv6 (Mobile IPv6) is one of the mobility management schemes proposed by the IETF (The Internet Engineering Task Force) and various IPv6-based mobility management schemes have been developed. They are directly involved with data transfer from MN (Mobile Node). In this paper, two kinds of schemes in analyzing of mobility management schemes are proposed. The signaling transfer and packet delivery procedures for each mobility management schemes are analyzed, respectively. The signaling cost for mobility management schemes are calculated, and the cost of each protocol are analyzed numerically. In other word, applying the sum of signaling cost and packet delivery cost to each mobility management scheme, their costs are analyzed. Finally, our performance evaluation results that the network-based mobility management scheme shows better performance in terms of overall cost.

TL;DR: A improved route optimization in PMIPv6-based multiple-LMA networks is proposed, which supports route optimization without any additional signalling because the LMA receives the state information of route optimization from PIG.
Abstract: Proxy Mobile IPv6 (PMIPv6) is designed to provide network-based mobility management support to an MN without any involvement of the MN in the mobility related signalling, hence, the proxy mobility entity performs all related signalling on behalf of the MN. The new principal functional entities of PMIPv6 are the local mobility anchor (LMA) and the mobile access gateway (MAG). In PMIPv6, all the data traffic sent from the MN gets routed to the LMA through a tunnel between the LMA and the MAG, but it still has the single point of failure (SPOF) and bottleneck state of traffic. To solve these problems, various approaches directed towards PMIPv6 performance improvements such as route optimization proposed. But these approaches add additional signalling to support MN`s mobility, which incurs extra network overhead and still has difficult to apply to multiple-LMA networks. In this paper, we propose a improved route optimization in PMIPv6-based multiple-LMA networks. All LMA connected to the proxy internetworking gateway (PIG), which performs inter-domain distributed mobility control. And, each MAG keeps the information of all LMA in PMIPv6 domain, so it is possible to perform fast route optimization. Therefore, it supports route optimization without any additional signalling because the LMA receives the state information of route optimization from PIG.

Abstract: This paper reinforced security under the network evaluation of wire/wireless integration of NEMO (NEwork MObility) supporting mobility and network-based PMIPv6 (Proxy Mobile IPv6). It also proposes SK-L2AM (Symmetric Key-Based Local-Lighted Authentication Mechanism) based on simple key which reduces code calculation and authentication delay costs. Moreover, fast handoff technique was also adopted to reduce handoff delay time in PMIPv6 and X-FPMIPv6 (eXtension of Fast Handoff for PMIPv6) was used to support global mobility. In addition, AX-FPMIPv6 (Authentication eXtension of Fast Handoff for PMIPv6) is proposed which integrated SK-L2AM and X-FPMIPv6 by applying Piggybacks method to reduce the overhead of authentication and signaling. The AX-FPMIPv6 technique suggested in this paper shows that this technique is better than the existing schemes in authentication and handoff delay according to the performance analysis.

TL;DR: An enhanced PMIPv6 route optimization, which considers the multi-6LoWPAN network environment and the host-based mobility management scheme in IP-WSN is proposed.
Abstract: Due to limited resources, the slow progressive development of wireless sensor networks (Wireless Sensor Network) through the development of hardware and power management technology is currently in progress for the development of the latest IP-based IP-WSN. Those with low-power devices on IPv6 can mount the 6LoWPAN (IPv6 over Low power WPAN) this is getting attention. In these IP-based sensor networks, existing IP-based schemes, which were impossible in wireless sensor networks, become possible. 6LoWPAN is based on the IEEE 802.15.4 sensor network and is a technology developed for IPv6 support. The host-based mobility management scheme in IP-WSN is not suitable due to the additional signaling; the network-based mobility management scheme is suitable. In this paper, we propose an enhanced PMIPv6 route optimization, which considers the multi-6LoWPAN network environment. All SLMA (Sensor Local Mobility Anchor) of the domain 6LoWPAN is connected to the SPIG (Sensor Proxy Internetworking Gateway) and perform cross-domain distributed mobility control. All information of SLMA in the 6LoWPAN domain is maintained by SMAG (Sensor Mobile Access Gateway) and route optimization is performed quickly and the route optimization status information from SPIG is stored to SLMA and is supported without additional signaling.

TL;DR: Analytical results show that different users with vastly different mobility and service patterns should adopt different integrated location and service management methods to optimize system performance, and show that the centralized scheme performs the best when the mobile user`s SMR is low and the session to mobility ratio is high.
Abstract: In this paper, we propose a cost-effective location and service management scheme in LTE (Long Term Evolution) networks, which a per-user service proxy is created to serve as a gateway between the mobile user and all client-server applications engaged by the mobile user. The service proxy is always co-located with the mobile user`s location database such that whenever the MU`s location database moves during a location hand-off, a service hand-off also ensues to co-locate the service proxy with the location database. This allows the proxy to know the location of the mobile user all the time to reduce the network communication cost for service delivery. We analyze four integrated location and service management schemes. Our results show that the centralized scheme performs the best when the mobile user`s SMR (service to mobility ratio) is low and (session to mobility ratio) is high, while the fully distributed scheme performs the best when both SMR and are high. In all other conditions, the dynamic anchor scheme is the best except when the service context transfer cost is high under which the static anchor scheme performs the best. Through analytical results, we demonstrate that different users with vastly different mobility and service patterns should adopt different integrated location and service management methods to optimize system performance.

Abstract: The Internet is becoming increasingly diverse and complex, the needs of user`s convenience is also various and increased. The task forces have been working on how to design the future Internet in satisfaction of user`s require and mobility management is one of the key issues to be considered. mobility management in the future Internet is still being designed in an "all-in-one" way where all management functions are tightly kept at a single location and this results in cost inefficiency that can be an obstruction to constructing flexible systems. In this paper, we propose a cost-effective function-distributed mobility management scheme that can enable more flexible future Internet construction. Furthermore, we show the effectiveness of our proposed system via a cost analysis and computer simulation with a random walk mobility model.

TL;DR: The proposed technique dMMS in terms of reducing the cost of the entire signaling were found to be excellent performance, and the signaling cost function in order to propose a new discrete analytical model is proposed, MN`s mobility and packet arrival patterns.
Abstract: Mobile IP is a simple and scalable global mobility solution. However, it may cause excessive signaling traffic and long signaling delay. So MN (Mobile Node) to the home network in order to reduce the number of location update signaling is necessary to reduce the delay. In this paper, the signaling overhead to be distributed evenly on the boundary of the regional network, each MN`s dynamic mobility and traffic load is adjusted according to the PMIPv6 (Proxy Mobile IPv6) networks in the proposed dynamic regional mobility management scheme (dMMS). Each user in a distributed network system that offers the least amount of signaling traffic is tailored to the optimized system configuration. Signaling cost function in order to propose a new discrete analytical model is proposed, MN`s mobility and packet arrival patterns. Location update and packet delivery costs to calculate the total average, the optimized area to determine the size of the network is proposed. The results of mathematical analysis, the proposed technique dMMS in terms of reducing the cost of the entire signaling were found to be excellent performance.

TL;DR: This paper proposes a cost-effective mobility management scheme which provides fast handover with multicasting support, efficient inter-LMA domain mobility management, and packet delivery methods in NEMO environments, and is compared with N-PMIPv6, rNemO, and PR-NEMO.
Abstract: Presently, there are many data and multimedia services available that are supported by Wi-Fi enabled mobile devices. As a result, demand for the ability to connect to the Internet anywhere is rapidly increasing, and network infrastructure becomes increasingly important. In response, there has been focus in the fields of industry and academics on cost-effective network mobility (NEMO) technologies. The cost-efficient protocol design of NEMO is intended to reduce demand for limited wired/wireless network bandwidth at the mobility signaling and packet delivery operations levels. In this paper, we propose a cost-effective mobility management scheme which provides fast handover with multicasting support, efficient inter-LMA domain mobility management, and packet delivery methods in NEMO environments. Our mathematical analysis, the Fast PR-NEMO scheme, is compared with N-PMIPv6, rNEMO, and PR-NEMO. In conclusion, our proposed scheme exhibits the best performance in terms of location, updating cost, and packet tunneling cost.

TL;DR: The proposed model removes the tunnel convergence issue and reduces router processing costs, and makes possible the performance of fast handover operations with adaptive transmission mechanisms in the inter-LMA domain.
Abstract: The development of multimedia applications followed by development of high-speed networks has improved the performance of mobile devices with high transfer speed broadband. Mobile internet access has made possible seamless indoor and outdoor mobile multicast services. Multicasting services are used to support efficient group communications. However, mobile multicasting services have two constraints: tunnel convergence and handover latency. Many protocols and handover methods have been proposed to address these problems. The inter-LMA optimized handover model for multicasting services has previously been proposed for PMIPv6-based networks. The proposed model removes the tunnel convergence issue and reduces router processing costs. It also makes possible the performance of fast handover operations with adaptive transmission mechanisms. In addition, the proposed scheme exhibits low packet delivery costs and handover latency in comparison with existing schemes, and ensures fast handover when moving the inter-LMA domain
TL;DR: An enhanced PMIPv6-based route optimization scheme which consider multi-6LoWPAN network environments and is based on the IEEE 802.15.4 sensor networks and is a IPv6-supported technology.
Abstract: The development of wireless sensor networks (WSNs) is progressed slowly due to limited resources, but it is in progress to the development of the latest IP-based IP-WSN by the development of hardware and power management technology. IPv6 over Low power WPAN (6LoWPAN) is capable of IPv6-built low-power devices. In these IP-based WSNs, existing IP-based techniques which was impossible in WSNs becomes possible. 6LoWPAN is based on the IEEE 802.15.4 sensor networks and is a IPv6-supported technology. Host-based mobility management scheme in IP-WSNs are not suitable due to the additional signaling, network-based mobility management scheme is more suitable. In this paper, we propose an enhanced PMIPv6-based route optimization scheme which consider multi-6LoWPAN network environments. All SLMA (Sensor Local Mobility Anchor) of the 6LoWPAN domain are connected with the SPIG (Sensor Proxy Internetworking Gateway) and performs distributed mobility control for the 6LoWPAN-based inter-domain operations. All information of SLMA in 6LoWPAN domain is maintained by SMAG (Sensor Mobile Access Gateway), and then is performed the route optimization quickly. The status information of the route optimization from SPIG is stored to SLMA and it is supported without additional signaling.
TL;DR: It is demonstrated that there exists an optimal threshold of the forwarding chain length, given a set of parameters characterizing the specific mobility and service patterns of a mobile user, that minimizes the overall network traffic.
Abstract: We propose efficient mobility management schemes based on pointer forwarding for Proxy Mobile IPv6 Networks(PMIPv6) with the objective to reduce the overall network traffic incurred by mobility management and packet delivery. The proposed schemes are per-user-based, i.e., the optimal threshold of the forwarding chain length that minimizes the overall network traffic is dynamically determined for each individual mobile user, based on the user`s specific mobility and service patterns. We demonstrate that there exists an optimal threshold of the forwarding chain length, given a set of parameters characterizing the specific mobility and service patterns of a mobile user. We also demonstrate that our schemes yield significantly better performance than schemes that apply a static threshold to all mobile users. A comparative analysis shows that our pointer forwarding schemes outperform routing-based mobility management protocols for PMIPv6.

TL;DR: In this paper, a low-cost global mobility management architecture and protocol procedure called LC-, which is based on Proxy Mobile IPv6, is proposed to eliminate the wireless link data delivery tunnel overhead between a mobile node and the access router.
Abstract: This paper specifies a low-cost global mobility management architecture and protocol procedure called LC-, which is based on Proxy Mobile IPv6. In LC-, mobility management is performed by the network entity. The benefit is the elimination of the wireless link data delivery tunnel overhead between a mobile node and the access router. To compare with the well-known Hierarchical Mobile IPv6 mobility management protocol and GPMIP, the location update, packet delivery, and total cost functions generated by a mobile node during its average domain residence time are formulated for each protocol based on Fluid-flow mobility model. Then, the impacts of various system parameters on the cost functions are analyzed. The analytical results indicate that the proposed global mobility management protocol can guarantee lower total costs.

Abstract: Mobile IPv6 (MIPv6) is a host-based protocol supporting global mobility while Proxy Mobile IPv6 (PMIPv6) is a network-based protocol supporting localized mobility. This paper makes its focus on how to reduce the longer delay and extra cost arising from the combination of authentication, authorization and accounting (AAA) and PMIPv6 further. Firstly, a novel authentication scheme (Proxy-AAA) is proposed, which supports fast handover mode and forwarding mode between different local mobility anchors (LMAs). Secondly, a cost analysis model is established based on Proxy-AAA. From the theoretical analysis, it could be noted that the cost is affected by average arrival rate and residence time.
