The newly emerging 5G mobile communication system requires an effective design of core network to cope with the mobile data traffic explosions. In this paper, we propose a new architecture for 5G mobile core network, RB-Core, to efficiently deal with such the data traffic explosion problem. The proposed RB-Core network is designed by adopting a distributed architecture and by using the Routing Bridge...
In Locator-Identifier Separation Protocol (LISP), the existing mobility control scheme is based on a centralized approach, in which the Map Server is used as a mobility anchor. However, such a centralized scheme has some limitations, including traffic overhead at central server, service degradation by a single point of failure, and larger handover delay. In this Letter, we propose a network-based...
The Locator Identifier Separation Protocol (LISP) has been made as an identifier-locator separation scheme for scalable Internet routing. The identifier-locator separation is also helpful for mobility support. The issue of mobility is a serious challenge in LISP. However, the existing LISP-based handover schemes tend to induce larger handover latency and packet loss. To overcome this problem, we propose...
This paper proposes an extension of Proxy Mobile IPv6 (PMIPv6) with bicasting for multi-homing and mobility support. In the proposed scheme, the Local Mobility Anchor (LMA) extends its Binding Cache Entry (BCE) for support of multiple bindings, and a mobile node (MN) performs the binding update to LMA. To support the handover, the LMA begins the bicasting of data packets to the New-Mobile Access Gateway...
This paper proposes an enhanced handover scheme of the Proxy Mobile IPv6 (PMIPv6) with partial bicasting in wireless networks. In the proposed PMIPv6 handover scheme, when a mobile node (MN) moves into a new network and thus its Mobile Access Gateway (MAG) performs the binding update to the Local Mobility Anchor (LMA), the LMA begins the `partial' bicasting of data packets to the new MAG as well as...
This paper addresses the multicast handover in the wireless networks based on the Proxy Mobile IPv6 (PMIP). The existing PMIP-based multicast schemes tend to induce severe packet losses, large handover delays and unnecessary data transmissions during handover. To overcome these problems, we propose the use of Multicast Handover Agent (MHA) for fast handover. In the proposed scheme, called PMIP-MHA,...
This paper proposes the two extensive data delivery schemes of Query-based PMIPv6 (Q-PMIPv6) and Signalling Query-based PMIPv6 (SQ-PMIPv6) in wireless networks. In the proposed Q-PMIPv6 scheme, when a correspond node (CN) sends the data packet to mobile node (MN), the Mobile Access Gateway (MAG), which CN is attached to, will send the binding query messages to Local Mobility Anchor (LMA) to get the...
Mobile IP (MIP) suffers from the so-called triangular routing problem. Moreover, MIP Home Agent (HA) tends to undergo server data traffic load, since it should deliver all the data packets toward mobile nodes. This Paper proposes a simple extension of MIP, called Query-based MIP (QMIP), in which the binding query to HA will be used to get the care-of address of a mobile node and to deliver the subsequent...
In this paper we propose the three schemes to support seamless multicast handover in the Proxy Mobile IPv6 (PMIPv6) based wireless networks. In the existing scheme, there is a problem of packet loss and larger handover latency, in which Mobile Node (MN) cannot receive the multicast data packets until the new Mobile Access Gateway (MAG) completes the Proxy Binding Update with Local Mobility Anchor...
This paper proposes an extension of proxy mobile IPv6 (PMIPv6) with bicasting for soft handover, named B-PMIPv6. The proposed scheme is compared with the existing PMIPv6 handover scheme by the theoretical analysis and the network simulator. From the experimental results, we can see that the proposed B-PMIPv6 scheme can provide smaller handover latency and reduce packet loss than the existing schemes.
The Proxy Mobile IPv6 (PMIPv6) was proposed to provide the Internet mobility for a host that is not equipped with any mobility software. However, the PMIPv6-based handover is still for further study. In this paper we propose a handover scheme of PMIPv6 with bicasting for IP handover. The handover performance of PMIPv6 can be enhanced with the help of bicasting in the network.
