In this paper, we propose a new micromobility management scheme, called Micro Mobile MPLS, that supports both mobility and quality-of-service (QoS) management in wireless networks. Our proposal includes two protocol variants. In the first variant, called FHMicroMobile MPLS, we consider the fast handoff (FH) mechanism, which anticipates the LSP (Label Switched Path) procedure setup with an adjacent neighbor subnet that an MN is likely to visit. This mechanism is proposed to reduce service disruption by using the link-layer (L2) functionalities. In the second variant, called FC-Micro Mobile MPLS, the forwarding chain (FC) concept is providedto track efficiently the host mobility within a domain. This concept is more suitable for MNs with high mobility rate. In order to assess the efficiency of our proposals, all underlying protocols are compared. To achieve this, we develop analytical models to evaluate the link usage cost, the registration updates cost, the handoff latency and the packet loss rate. Numerical and simulation results show that the proposed mechanisms can significantly reduce the registration updates cost and provide low handoff latency and packet loss rate under various scenarios.</span></span><span style="font-family: ";Arial";,";sans-serif";; font-size: 9pt;"></span></p&gt

Mechanisms of quality of service and mobility in 4G networks

“…In this case the results of the handoff are the same as using only the MIP. In Although the results are good as seen in [4], this is a solution that shows the functionality of Micro Mobile MPLS without utilizing a MIP, in other words, without changing the FEC for the CoA when roaming as described in [1][2] [3],replacing this situations for the establishment or lack there of in the links. A better option is integrating the MIP with the MPLS, but this implementation is focused towards macromobility as shown in [5].…”

“…To simulate Micro Mobile MPLS [1] [2] [3], its necessary extend the LDP agent of the MPLS nodes to be able to unpack the packets sent using MIP, obtain the CoA, and then use it as a FEC. This process is made possible by accessing the headers of MIP and MPLS through pointers.…”

“…Lastly there is an option to use CIMS which supports HMIP, and extend the nodes used in CIMS and the MPLS nodes similar to the way done in MIP and MPLS, with the additional advantage of a HMIP at a Micro mobility level, decreasing the quantity of signalization, contrary to a MIP. This is the best way to reach the Micro Mobile MPLS proposed in [1] [2] [3], due to the use of a HMIP and its similitude's at a regional register level with MIP-RR.…”

“…Mobile MPLS in [1] [2] [3]. On the level of Micro mobility, Mobile MPLS greatly reduces the handoff while roaming between one base station and another.…”

Handoff mechanism in MPLS enabled wireless network

“…Several MIP-MPLS based solutions [10][11] have been proposed for micro level to handle intra domain mobility. Reference [12] describes the performance of MIP based network on hierarchical MPLS (H-MPLS) platform.…”
