Implementation of a HMIPv6 extension in the INET and xMIPv6 simulation framework with dynamic MAP discovery for OMNeT 4.x
In order to perform a simulative evaluation of the Hierarchical Mobile IPv6 protocol (HMIPv6) OMNeT++ simulation environment was used. OMNeT++ simulation package - INET framework and xMIPv6 was enhanced with an extension for HMIPv6, which includes Neighbor Discovery protocol, IPv6 router and the implementation of a Mobility Anchor Point (MAP). The simulation model was implemented as defined in RFC 5380 Hierarchical Mobile IPv6 - HMIPv6 Mobility Management. Enhancements are recognized in terms of an upgraded Router advertisement (RA) packet with option data about the MAP. We used dynamic MAP discovery, based on MAP option propagation in Router Advertisements from the MAP to the Mobile Node through certain (configured) router interfaces, within the routers in a network.
