( Moneeb Gohar ),( Seok Joo Koh ) 한국정보처리학회 2016 Journal of information processing systems Vol.12 No.2

System Architecture Evolution (SAE) with Long Term Evolution (LTE) has been used as the key technology for the next generation mobile networks. To support mobility in the LTE/SAE-based mobile networks, the Proxy Mobile IPv6 (PMIP), in which the Mobile Access Gateway (MAG) of the PMIP is deployed at the Serving Gateway (S-GW) of LTE/SAE and the Local Mobility Anchor (LMA) of PMIP is employed at the PDN Gateway (P-GW) of LTE/SAE, is being considered. In the meantime, the Host Identity Protocol (HIP) and the Locator Identifier Separation Protocol (LISP) have recently been proposed with the identifier-locator separation principle, and they can be used for mobility management over the global-scale networks. In this paper, we discuss how to provide the inter-domain mobility management over PMIP-based LTE/SAE networks by investigating three possible scenarios: mobile IP with PMIP (denoted by MIP-PMIP-LTE/SAE), HIP with PMIP (denoted by HIP-PMIP-LTE/SAE), and LISP with PMIP (denoted by LISP-PMIP-LTE/SAE). For performance analysis of the candidate inter-domain mobility management schemes, we analyzed the traffic overhead at a central agent and the total transmission delay required for control and data packet delivery. From the numerical results, we can see that HIP-PMIP-LTE/SAE and LISP-PMIP-LTE/SAE are preferred to MIP-PMIP-LTE/SAE in terms of traffic overhead; whereas, LISP-PMIP-LTE/SAE is preferred to HIP-PMIP-LTE/SAE and MIP-PMIP-LTE/SAE in the viewpoint of total transmission delay.

MPLS 네트워크에서 PMIP 기반의 이동성 지원 방안

임태형,이성근,박진우,Lim, Tae-Hyong,Lee, Sung-Kuen,Park, Jin-Woo 한국전기전자학회 2009 전기전자학회논문지 Vol.13 No.4

IETF에서 제안된 네트워크 기반의 이동성 지원 방식인 Proxy Mobile IP는 이동 단말이 아닌 LMA(Local Mobility Anchor)와 MAG(Mobile Access Gateway)등의 네트워크 요소가 이동성 지원 기능을 수행하기 때문에 단말 기반의 이동성 지원 방식인 MIP의 문제점을 해결하고 MIP보다 향상된 핸드오버 성능을 보인다. 그러나 여전히 PMIP은 MIP와 마찬가지로 IP의 Best Effort Service를 기반으로 하기 때문에 다양한 실시간 멀티미디어 서비스에 대한 QoS를 보장하지 못한다. 이러한 문제를 해결하기 위해 본 논문에서는 MPLS 네트워크에서 PMIP기반의 이동성 지원 기술을 적용하여 이동성과 QoS의 보장을 모두 제공하는 네트워크 구조 및 핸드오버 절차를 제안한다. Proxy Mobile IP in IETF is a network-based mobility management scheme to solve the problem of host-based mobility management scheme, Mobile IP. PMIP shows the better performance in the aspect of mobility, but PMIP, as a legacy of Mobile IP based on "best effort service", lacks of consideration of QoS. In this thesis, a novel mobility support scheme is proposed for mobility and QoS support based on PMIP in MPLS networks.

Last Glacial Maximum climate over Korean Peninsula in PMIP3 simulations

Kim, S.J.,Kim, J.W.,Kim, B.M. Pergamon Press 2015 QUATERNARY INTERNATIONAL Vol.384 No.-

The Last Glacial Maximum (LGM) at 21,000 years before present is a marked climate event with thick ice sheets over North America and Europe and associated sea level drop of about 120 m. We used the most updated coupled climate model results to analyze the climate change over Korea for the LGM. Eight coupled models (CCSM, CNRM, COSMOS, FGOALS, IPSL, MIROC, MPI, and MRI) were used to analyze the LGM climate. With LGM boundary conditions, surface air temperature decreases almost everywhere in all seasons with the largest cooling in winter and least cooling in summer. Overall, in the LGM, the multi-model annual-mean cooling over Korea is 5.85 C<SUP>o</SUP>, which is consistent with proxy evidence using pollen reconstructions. Associated with the surface cooling, precipitation decreases in general, with the largest reduction in winter by 56%, but in summer precipitation increases by 12% in the LGM over Korea. Overall, precipitation decreases by about 14% in the LGM over Korea. The surface cooling tends to increase surface pressure almost everywhere over Asia. The sea level pressure increase is especially larger in high latitudes and this leads to the easterly wind anomaly in northern part of Korea. On the other hand, in South Korea, the increase in surface pressure leads to the westerly wind anomaly. The increase in surface pressure associated with surface cooling leads to the anticlockwise wind anomalies in the LGM over Korea.

본 논문에서는 IETF NetLMM WG에서 표준화되고 있는 Proxy-MIPv6을 기반으로, 빠르고 효율적인 핸드오프를 지원하는 망 기반의 이동성 지원 방안을 제안하였다. 제안된 방식은 Mobile Access Gateway (MAG)간의 dynamic virtual hierarchy 망 구조를 활용함으로써 망의 확장성과 안정성을 제공하고, Policy Store(PS) 기반의 빠른 인증 및 프로파일 획득 기법을 활용함으로써 빠르고 효율적인 핸드오프를 제공할 수 있다. 또한, 제안된 방식과 기존의 PMIPv6의 성능 분석 및 토의를 통하여 제안된 방식의 우수성을 알 수 있다. In this paper, we propose an enhanced handoff support scheme based on network-based mobility management protocol, Proxy Mobile IPv6 (PMIPv6), which is actively standardized by the IETF NETLMM working group. By utilizing the dynamic virtual hierarchy network architecture between mobile access gateways (MAGs), the proposed scheme can support network scalability and reliability to wireless access network. In addition, we propose pre-authentication process based on the policy store (PS) to support a fast and seamless handoff. We evaluate the performance of the proposed scheme in terms of handoff delay and end-to-end delay thru computer simulation. Thru various computer simulation results, we verified the superior performance of the proposed scheme by comparing with the results of other schemes.
