Design and Implementation of Micro Mobile MPLS for NS-2

In this paper, the authors extend NS-2 to simulate Micro-Mobile MPLS frameworks. The extension supports most of important mechanisms used in the literature. The simulator is based on IEEE 802.11. The important mechanisms are multi-channel support used in IEEE 802.11, directional antennas, multiple interfaces, L2-handoff, L2-trigger, bicasting, pre-established LSP, and buffering mechanism. MPLS modules used in this simulator is based MNS. This simulator could be configured to assess performance of Mobile MPLS protocols such as micro mobility-enabled multiprotocol label switching (M-MPLS), Fast Handoff (FH) and master forwarding chain (MFC)-Micro Mobile MPLS, [23] and MiM-MPLS.
